Digimon and Appmon: Nature vs Domestication

So Digital World Archive posted an article How Appmon inherits Digimon's Legacy a while back and two paragraphs in particular caught my eye:

The biggest difference with Digimon, even when comparing just the original settings, is how the Appmon lack the focus in the “Law of the Jungle” that basically shaped the whole idea of fighting Digimon back in the day. I mean, Appmon have special moves and can fight, but it’s a lot less part of their identity as “Appmon” than it is for “Digimon”, which were basically built to fight (That is, you can’t really find a definition for Digimon in the early days that didn’t mention this nature, while Appmon’s definition only talks about how they “were made for the good of systems and humans”, which I see as a clear difference between Appmon and Digimon).

But at the same time, I can see this as an evolution from “Digimon” to “Appmon”. The late 1990s and early 2000s had the internet as a much more mysterious place that put fear in the minds of many people. So maybe if you were to understand “Digimon” as having the focus on “monsters” as symbolizing this chaotic nature of the early internet, then having the modern “Appmon” be first and foremost Apps that exist to help mankind could represent how nowadays our life is much more integrated to the internet than before (Even though I would say it’s much more dangerous nowadays exactly because of how integrated everything is).

To use an analogy: if Digimon are wolves (Canis lupus) then Appmon are domesticated dogs (Canis lupus familiaris)

This leads to my thoughts for how Digimon and Appmon can coexist:

Once upon a time there were the Wild Ones, the monsters that terrorized human myths and legends for centuries: These beings were known as the Kemonogami before they, along with their world, underwent the process of digitization due to humanity's development of digital technology, and specifically the Network, to become the first Digital Monsters: Digimon. Their home, now known as the Digital World, exists within the deepest depths of the Net Ocean: Beyond even the Dark Web and the reach of the most skilled hackers.

Eventually however, humanity discovered these Digital Monsters and became fascinated by them. And as is human nature, this fascination led to the desire to domesticate Digimon; just as Onmyōji purportedly tamed and controlled Kemonogami. After decades of research, programmers managed to reverse engineer the unique physiology of Digimon which was used to convert application programs into the second Digital Monsters: Appmon

And while humans can have partner Digimon, this is akin to bonding with a supernatural entity (think ghosts from Ghostbusters) that will battle to protect you hence why such people are called "Tamers," even when Digimon possess full sapience

Radio Tuning and Volume Controls, Part 1: The Rules

At the risk of too many technically dense posts in sequence, I’m following up my post on the minutiae of battery backups with two posts on the minutiae of radio tuning and volume controls! These “explainer” posts will likely be the most time-consuming for me to write, so I want to knock them out rather than turning them into Big Daunting Things in my head that I then procrastinate on.

In Part 2 of this post, we will explore the weirdnesses of radio tuning and volume controls. But first, we need to explore how they work in the first place. And before we explore that, we need to explore why alarm clocks have radios or other music-playing apparatuses in the first place. So let’s do it!

Why do so many alarm clocks have radios, CD players, or other music players?

There’s an obvious reason and a slightly less obvious reason! The obvious reason is that it saves space on a nightstand. I know my nightstand barely has enough space for everything on it, and I can imagine pretty much nobody wanted to cram a CD boombox and an alarm clock onto their bedside table. Combining these devices reduces their footprint!

The slightly less obvious reason is that these “combo” alarm clocks tried to give you a more pleasant sleeping and waking experience than alarm clocks of yore. Most people don’t enjoy waking up to bells ringing or obnoxious buzzing or beeping, though for some of us, it may be the only way to get us out of bed. But for others, it might be nicer to wake up to a favorite song, or the voice of your favorite anchor on NPR. That’s why alarm clocks with radios, CD players, or other audio sources typically let you set these sources as the alarm sound, which wouldn’t be possible if the radio or CD player was an entirely separate device.

Pretty much all of these alarm clocks also go a step further. They don’t just try to help you wake up peacefully, they also try to help you fall asleep peacefully too. Tons and tons of alarm clocks have a sleep timer, which shuts off the radio or CD player automatically after a set time. That way, you can put on soothing music or a boring news station to fall asleep to, and then have the sound shut off automatically once you’re asleep. I feel like sleep timers are something surprisingly few people use or even know about, though they’re included on practically every alarm clock with a radio or CD player ever made.

Now, here’s the tricky thing. The audio people want to fall asleep to is not the same as the audio they want to wake up to. (Or the audio they listen to during the day!) Maybe you’re the kind of person who puts on soothing classical at a low volume to lull you into slumber. But you’re a deep sleeper, so you need the guitars of heavy metal playing LOUD to get you out of bed. (If you’re that person, I applaud you for your rich and varied music tastes.)

I don’t think there are really that many people using their alarm clocks to the max in this way, setting the CD alarm, using the sleep timer, and letting their tastes meander across every genre and volume level of music. But when that rare human being comes along, alarm clocks have to be prepared. It’s helpful when they have the ability to play one thing at one volume (such as during the sleep timer), then switch themselves to a different thing at a different volume (such as for the alarm sound). And that leads nicely into our discussion today!

Analog vs. digital controls

If you’re young and sprightly like me, you may have no idea how radio works. (Well, I know a little about how radio works, but mostly because I’m an alarm clock nerd, not because I really listen to it. Though NPR slaps, I will say.) Both AM and FM radio stations broadcast at specific frequencies, measured in kilohertz (for AM) or megahertz (for FM). Using FM as an example, one station may be located at 91.1 MHz, then another at 91.3, then another at 91.5, etc. The important thing to know is that, unlike “stations” on an app like Spotify, real radio stations are arranged in a numeric sequence, and you change between them by changing the frequency the radio is set to receive. The process of changing this frequency to the number you want is called tuning.

If you’re an alarm clock designer, you might approach designing controls for radio tuning in a similar way as you might for volume. That’s because volume controls, like radio tuning controls, also need to move through a series of numbers in sequence. These numbers are more obvious. They are an arbitrary range the alarm clock designer chooses, from mute all the way up to super-super-loud.

Both radio tuning and volume controls (on alarm clocks or other devices) can be analog or digital. This is a surprisingly important distinction that I want to explain as carefully as I can.

Digital controls

I’m actually going to explain digital controls first, because they are more familiar to most people. With a digital control for radio tuning or volume, you press a button or turn a dial, and your action sends a command to the device’s motherboard, which changes the numeric value for radio frequency or volume by a preset amount. The resulting value is typically shown on a screen. You know when you press the volume-up button on your TV remote, and the screen shows that the volume changed from 29 to 30? That’s a digital control.

Below is a an alarm clock (a Sony ICF-CD853V) with a prototypical example of digital radio tuning. The radio frequency (87.5 MHz) is shown at the bottom of the screen. The “Tune / Time Set” buttons allow you to decrease or increase the radio frequency. And there are buttons numbered 1 through 5 on the top of the alarm clock for “Preset Tuning,” which is almost always a telltale sign of digital radio tuning. I’ll explain what those do in just a moment.

There are two crucial things to understand about digital controls. First, they change radio frequency or volume in discrete steps, rather than continuously. If volume is on a scale from 0 to 30, you can’t set the volume to 5.5, or 3.3333333, or 2.57684749249. You can set it to 2, or 3, or 4, or 5. This could be considered limiting for a volume control, because what if you want to listen to music at 5.5, and 5 is too quiet and 6 is too loud, gosh darn it? But alarm clock designers can usually resolve this problem by including enough volume options. And changing in discrete steps is actually really helpful for radio tuning, because radio stations are arranged in discrete steps. You want to move from 91.1 FM to 91.3 FM without ending up in between. If you end up at 91.2 FM, where no station exists, I believe you'll hear a little bit of both radio stations on either side simultaneously, which is what we call “not ideal.”

Second, you can use a digital control to change radio frequency or volume, or the electronics within the device can change the radio frequency or volume themselves. There are so, so many reasons why this is important. With radio frequency, it allows for preset stations, where you save the stations you listen to most, and at the touch of a button, the electronics within the device can leap from the old frequency to the one you selected, regardless of how far apart they are. (That’s what those 1 through 5 buttons do on the alarm clock pictured above! I could save NPR as preset 1 and jump to it whenever I want.) With alarm clocks specifically, digital controls also allow you to set a radio frequency or volume level for the alarm that is different from whatever you were last listening to. At the alarm time, the clock can change itself to the new radio frequency or volume level. Finally, digital controls also allow you to adjust the radio frequency or volume without physically interacting with the device, such as by using a remote control.

Analog controls

This is all in contrast to analog controls. With an analog control for radio tuning or volume, you turn a dial, and the dial physically interacts with the circuitry of the device in a way that I honestly don’t fully understand, and the radio frequency or volume changes along a continuum (not stepwise or discretely). The resulting radio frequency or volume is not shown on a screen, because (a) the device doesn’t know exactly what radio frequency or volume it’s set to (yes, really), and (b) the radio frequency or volume isn’t an exact, discrete number.

Below is an alarm clock (a Sony ICF-C630) with a prototypical example of analog radio tuning. An estimate of the radio frequency is shown on the dial scale, which looks like a ruler and is located below the display. The radio tuning dial is the small gray wheel on the lower-right side of the clock. As you rotate the dial, a mechanical linkage moves the red pointer on the dial scale, showing you roughly which station you are tuned to. (If you’re wondering why the frequencies on the dial scale are weird numbers, it’s because this isn’t a U.S.-market clock, and radio frequencies work differently in different countries.)

Analog controls will probably make more sense if we discuss the physical controls themselves. Both analog and digital controls can be dials. But a digital dial can make more than one full rotation, while an analog dial is restricted to one full rotation or less. An analog dial also never clicks from one “step” to the next, while some digital dials do. Using volume as an example, an analog volume control is usually a little dial or wheel on the side of a device that smoothly, freely rotates from one endpoint (mute) to another endpoint (the loudest volume possible). If you’ve ever had a Nintendo device (like a 3DS) with a volume slider on the side, that’s a perfect example of an analog volume control. (Though on alarm clocks, dials are much more common than sliders.)

As I said earlier, analog controls change radio frequency or volume continuously, not stepwise or discretely. They have an infinite amount of settings between their two endpoints. So you can dial in the perfect volume level for your listening (though you may get sucked into an obsessive loop doing it), but you can also find yourself tuned between two radio stations, which sucks. You’ll rarely, if ever, tune perfectly to 91.1 FM, so you better get comfortable with “good enough.” Devices with analog controls also can’t change these controls themselves. So if an alarm clock’s radio tuning dial or volume dial is set to a particular station or volume, that’s the station or volume the alarm clock will be using, until you physically rotate the dial. So no preset radio stations, no programming a unique radio station or volume level for the alarm, and no changing the station or volume using a remote control.

Analog volume controls don’t typically indicate the volume level, but it’s easy enough to hear if the music is already playing. Analog radio tuning controls do typically indicate the estimated radio frequency, because you don’t always know which station you’re on just by listening to it, unless the announcers tell you. Above, I showed you an example of a dial scale, which is the most common kind of radio frequency display for analog tuning. But there are others. Sometimes radio frequency numbers mechanically rotate through a little plastic window, like on the Sony ICF-CD815, shown below-left. And sometimes the radio frequency numbers are printed on the dial itself, like on the HoMedics SS-6000, shown below-right. (You might need to zoom in to see the radio tuning dial, which is on the lower-right side of the clock.)

Time for a break!

I know this is a pretty technically dense post, and I really appreciate you bearing with me. Here’s the good news: now that you’ve learned all this information, you will be better able to appreciate the weird and fun things I’m going to show you in Part 2! So go get hydrated, have a snack, touch grass, and then join me for Part 2!

The Role of Mixers in Live Sound: A Comprehensive Overview

Imagine standing in the middle of a concert, surrounded by the perfect blend of instruments and vocals, every sound complementing the other seamlessly. This magic doesn’t happen by accident—it’s the work of a mixer. Mixers, often referred to as the heart of live sound systems, play a pivotal role in ensuring every performance sounds flawless. Whether it’s a small gig at a local café or a massive stadium concert, mixers are an essential part of live sound setups.

Let's understand what  mixers do, why they’re important, and how they bring live performances to life. Whether you're an aspiring sound engineer, a musician, or simply curious, this comprehensive overview will break it all down in simple terms.

What is a Mixer?

At its core, a mixer is a device that takes multiple audio signals—like vocals, guitars, keyboards, and drums—and blends them into a cohesive output. Think of it as the control center for all the sounds in a live performance.

Mixers allow you to:

Adjust the volume of each input (like turning up the vocals or lowering the bass).

Shape the sound using equalizers (EQ) to balance frequencies.

Add effects like reverb or delay to enhance the audio.

Route signals to different outputs, such as speakers, monitors, or recording devices.

Whether you're using a compact analog mixer or a high-tech digital console, the principles remain the same: taking raw sound and refining it for the audience's ears.

Why Mixers Are Crucial for Live Sound

1. Balancing the Audio

Live performances often involve multiple sound sources—vocals, instruments, backing tracks, and sometimes even crowd noise. A mixer ensures that no single element overpowers the rest, creating a harmonious balance that’s pleasant to listen to. For instance, without a mixer, a loud drum kit could drown out a singer's voice, making the performance feel chaotic.

2. Customizing the Sound

Every venue has unique acoustics. What sounds great in a small indoor space might not work for an open-air festival. Mixers allow sound engineers to adapt the audio for different environments. By tweaking EQ settings, they can reduce echo in large halls or add warmth to a cold-sounding room.

3. Providing Real-Time Control

Live performances are unpredictable. A singer might step away from the mic, or a guitarist might accidentally play too loudly during a solo. With a mixer, sound engineers can make instant adjustments to keep everything running smoothly.

Key Features of Mixers

When exploring mixers, it’s important to understand their features. Here are some key components that make mixers so versatile:

1. Channels

Mixers have multiple channels, each dedicated to a specific input (e.g., a microphone or instrument). Small mixers might have 4-8 channels, while larger ones can have 32 or more. Each channel has its own controls for volume, EQ, and effects, giving you granular control over individual sound sources.

2. Equalization (EQ)

EQ lets you shape the tone of each input. For example:

Boost the treble for a brighter vocal sound.

Cut the bass to reduce rumbling noises.

Adjust midrange frequencies for clarity.

EQ is essential for ensuring that all elements in a mix complement each other without clashing.

3. Aux Sends and Effects

Auxiliary (aux) sends allow you to send specific audio signals to different destinations. For instance, you can send a mix of vocals and instruments to on-stage monitors so performers can hear themselves.

Many mixers also come with built-in effects like reverb, delay, and compression, which can add depth and polish to the sound.

4. Faders and Pan Controls

Faders control the volume of each channel, while pan controls adjust the stereo placement of a sound. For example, you can pan a guitar slightly to the left and a keyboard slightly to the right for a more immersive stereo effect.

5. Digital vs. Analog Mixers

Analog Mixers: Known for their simplicity and tactile controls, analog mixers are a great choice for beginners or smaller setups.

Digital Mixers: These offer advanced features like presets, wireless control via apps, and the ability to handle complex setups. They’re ideal for larger venues or tech-savvy users.

How Mixers Enhance the Audience Experience

A well-mixed performance can transform how the audience experiences live music. Here’s how mixers contribute to a great show:

Clarity: Mixers ensure that every instrument and vocal is heard clearly, even in a crowded or noisy environment.

Energy: By controlling dynamics, mixers can make the music feel more powerful and engaging.

Emotion: Effects like reverb and delay can add atmosphere and emotion to a performance, making it more memorable.

Tips for Using Mixers Effectively

If you’re new to mixers, here are some practical tips to get started:

Start Simple: Focus on getting the basics right—like balancing volume levels—before diving into advanced features.

Learn to Use EQ: Understanding how to use EQ can make a huge difference in the quality of your mix.

Practice in Real Settings: Mixing in a live environment is different from mixing in a studio. Practice in different venues to get a feel for how acoustics affect sound.

Invest in Quality Gear: A reliable mixer can make your life much easier, especially during live performances. Purchasing from reputable audio shops ensures you get equipment that’s durable and built to perform.

Conclusion

Mixers are more than just pieces of equipment—they’re the bridge between raw sound and a polished performance. By understanding their features and functions, you can unlock their full potential and deliver a live sound experience that captivates your audience.

Whether you’re a performer, a sound engineer, or just someone passionate about music, investing time in learning about mixers is well worth it. After all, great sound doesn’t happen by chance—it’s the result of careful planning, skilled mixing, and quality equipment.

So the next time you’re at a concert or gig, take a moment to appreciate the mixer and the person behind it. They’re the unsung heroes making the magic happen!

Arduino Due vs. Mega: A Comprehensive Comparison

What is Arduino Due and Mega?

The Arduino platform has revolutionized the world of DIY electronics, providing hobbyists and professionals alike with versatile and powerful microcontroller boards. Among the myriad of options, the Arduino Due and Arduino Mega stand out for their advanced features and robust performance. The Arduino Due, introduced in 2012, is the first Arduino board based on a 32-bit ARM core microcontroller, the Atmel SAM3X8E. In contrast, the Arduino Mega, built around the 8-bit ATmega2560 microcontroller, is known for its abundant I/O pins and memory. Understanding the differences between these two boards can help in selecting the right one for specific projects, enhancing both functionality and efficiency.

Processing Power and Performance

The processing capabilities of the Arduino Due and Mega are distinctly different, primarily due to their core microcontrollers. The Arduino Due, with its 32-bit ARM Cortex-M3 processor running at 84 MHz, offers significantly higher processing power compared to the Arduino Mega's 8-bit ATmega2560, which operates at 16 MHz. This difference in architecture and clock speed means that the Due can handle more complex calculations and tasks faster and more efficiently than the Mega. For projects requiring high computational power, such as real-time data processing or handling multiple sensors simultaneously, the Due is the superior choice. However, for simpler tasks, the Mega's processing power may suffice.

Memory and Storage Capabilities

Memory is another critical aspect where the Arduino Due and Mega diverge. The Arduino Due is equipped with 512 KB of flash memory for code storage and 96 KB of SRAM for data. On the other hand, the Arduino Mega has 256 KB of flash memory and 8 KB of SRAM. Additionally, the Due features a Direct Memory Access (DMA) controller, which allows for efficient memory operations, freeing up the CPU to handle other tasks. These memory enhancements make the Due more suitable for applications requiring large codebases and significant data handling, such as advanced robotics or sophisticated control systems. The Mega, with its more modest memory, is ideal for less demanding applications.

Input/Output Capabilities and Expansion

Both the Arduino Due and Mega are renowned for their extensive input/output (I/O) capabilities, yet they cater to different needs. The Mega boasts a whopping 54 digital I/O pins, 16 analog inputs, and 4 UARTs, making it ideal for projects that require multiple sensors, actuators, or communication interfaces. The Due, while offering fewer digital I/O pins at 54, includes 12 analog inputs and 4 UARTs, along with additional features like two DAC outputs for analog signal generation and enhanced PWM capabilities. These features provide the Due with superior analog output capabilities, making it suitable for applications like audio processing or advanced signal generation.

Power Consumption and Compatibility

Power consumption and compatibility are practical considerations when choosing between the Arduino Due and Mega. The Due operates at 3.3V logic levels, which makes it more power-efficient than the Mega, which uses 5V logic levels. This lower voltage operation is beneficial for battery-powered projects where energy efficiency is crucial. However, the 3.3V logic also means that the Due is not directly compatible with 5V components without level shifters. The Mega, with its 5V logic, offers broader compatibility with existing Arduino shields and components, making it a versatile choice for a wide range of projects. Understanding these power and compatibility nuances can help in making an informed decision based on the project's specific requirements.
