Sam Petts-Davies's Setup for Thom's 'Everything' Tour

A photo of the setup, shared by Sam on his instagram account with the caption "tour begins tonight. i’ll be parked at front of house with this box of esoterics for the duration. it’s going to be something really special."

Thom's solo tour has just begun with a show in Christchurch, New Zealand, and Sam Petts-Davies is along for the ride!

Since Radiohead's earliest shows, there's always been at least a few effects added by an engineer at the FOH (front of house) mixing desk to keep the band's sound clear and coherent. With Radiohead, that role was filed by Jim Warren. Even after Thom started bringing pedalboard full of vocal effects on tour, Jim continued to apply additional effects including plugins such as the Waves C4 multiband compressor for vocals. You can find more info on Jim's work in these posts.

For The Smile, even fewer hardware effects were needed at the FOH desk, in part due to Thom's expanded vocal pedalboard. In 2022, the Smile's mix engineer mainly relied on plugins from an Avid VENUE S6L-32D digital desk, supplemented only by a TUBE-TECH CL 1B Tube Optical compressor (presumably for Thom's vocals).

It's clear that when Thom is performing totally solo, a different approach is needed. But it's hard to imagine that any past FOH setup has been so full of hardware effects! And not just effects, but also modulators and an usual mixer, as we'll see....

For those who don't know, Sam initially served as a engineer under Nigel during the recording of Junun in 2015. He subsequently did engineering work on Spectre, A Moon Shaped Pool, and on the strings for the OKNOTOK singles. In 2018, he co-produced the soundtrack to Suspiria with Thom, and apparently Thom was a fan because Sam received a full production credit for Thom's soundtrack to Confidenza. He also produced both of the Smile albums released this year: Wall of Eyes and Cutouts.

For comprehensibility, we've divided the setup into four sections: the core, the modular, the pedals, and the rack. We'll start with the core setup.

Core Setup

This section is the nexus: receiving input from Thom's stage setup, sending it through various effects, and mixing it all together. The Matrix Mixer is using to both mix together and feedback the various effects in Thom's eurorack setup. The Yamaha DM3-D appears to be the central mixing console for the entire setup. Despite its small size, the Yamaha boasts 22 channels and a huge range of built-in effects, and on top of that it can also run VST plugins.

Modular Setup

In the decade since Thom first used a Make Noise Shared System Plus to process his voice and piano, his eurorack effects setup has expanded quite a bit! The Shared System is designed to be both a sound generator and an effects processor, and since then Thom has created dedicated setups for each of those applications. This setup is the effects processor, with lots of delays, filters, and reverbs, plus some LFOs and CV sources to modulate those effects. The additional Doepfer case that Thom has on stage, might have some of his sound generators, but knowing Thom it could just as easily be even more Make Noise Echophon delays.

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.

This is cool: A new software startup, GPU Audio (gpu.audio) seems to have done what many said was impossible: Adapt audio DSP algorithms to run on graphics processors, with solutions and an SDK to let app and plugin developers tap into the power of Nvidia, AMD, and Apple M-series chips.

This means the capability to run multiple tracks with complex effects processing and audio/synth plugins in near-realtime, providing very low latency (ie roundtrip time) for monitoring while recording.

Normally, this is stuff your CPU would handle, but even high-end CPUs aren’t optimized to do that kind of digital signal processing. That’s why, for the last few decades, producers have relied on specialized audio DSP hardware to get that kind of power, like Avid’s HDX cards for ProTools, Universal Audio’s plugins powered by UAD2 cards, etc.

For Mac users, the multiple GPU cores in their M-series chips can now be tapped, with no extra hardware required.

Getting Started with Audio Design in Embedded Systems

Adding audio capabilities to embedded systems can make a big difference in the user experience, whether you are creating home automation, wearable, or industrial devices. Even just simple sound prompts or alerts can improve user interaction considerably.

This article takes you through the ways embedded devices process, store, and play back audio—without getting too involved in the subjective realm of "sound quality."

Audio Begins as Analog

In the real world, sound is analog. That is to say, any audio we wish to record and play back must first be converted from analog to digital—because embedded systems process digital data.

This conversion to digital involves two important parameters: sampling rate and bit depth.

Sampling rate is the number of times the sound signal is recorded per second. The Nyquist-Shannon Sampling Theorem states that your sampling rate needs to be a minimum of twice the highest frequency sound you'll be recording.

Bit depth is the degree of precision with which each of those sound samples is recorded—more bits = more detail, but also more memory consumption.

A real-world example: Telephone audio uses just 400–3400 Hz bandwidth, far lower than the full range of human hearing (20 Hz to 20 kHz), yet it’s good enough to understand speech and even recognize a person’s voice.

Choosing the Right Bit Depth

Bit depth specifies how much volume each audio sample can represent. For instance, an 8-bit sample can have 256 levels, and a 16-bit sample can have 65,536.

In embedded systems, ADCs (Analog-to-Digital Converters) accomplish this task. But the usable resolution in practice is usually a bit less than what's on the datasheet because of such imperfections as noise and signal distortion. A useful rule of thumb: deduct 2 bits from the advertised bit depth to arrive at a realistic expectation (e.g., use a 12-bit ADC as if it were really 10-bit).

Storing and Compressing Audio

Most embedded systems keep audio in PCM (Pulse Code Modulation) or WAV format. Both are straightforward and convenient but tend to use a lot of memory space. For example, CD-quality audio at 44.1 kHz with 16 bits of depth can occupy more than 700 KB for a single second of mono sound.

To conserve space, programmers usually:

Compact audio using MP3 (although this needs more processing power).

Pre-process the sound to restrict bandwidth and dynamic range through software such as Audacity.

Lower the sampling rate and bit depth to accommodate the hardware's capabilities better.

In the event of a limited processing power, external decoders can decode MP3 files in order to remove the workload from the primary processor.

Playing the Audio

Once the audio is ready, it has to be converted back to analog for playback. This is where DACs (Digital-to-Analog Converters) come in. PCM data goes directly to a DAC, while compressed formats need to be decoded first.

You’ll also need a low-pass filter after the DAC to remove high-frequency noise caused by sampling. If your system handles stereo output, you’ll need two DACs and filters.

Alternatively, many microcontrollers use I2S (Inter-IC Sound)—a digital audio protocol designed for efficient transmission of stereo sound using just three wires. I2S is flexible with sampling rates and bit depths, making it ideal for embedded applications.

Amplifying the Sound

Whether using DAC or I2S, the output signal is too weak to drive a speaker directly. That’s where audio amplifiers come in.

There are three main types:

Class-A: Great quality, but inefficient—rarely used in embedded systems.

Class-AB: More efficient, commonly used in chip form.

Class-D: Highly efficient, compact, and perfect for embedded devices.

Class-D amplifiers work by converting the signal to PWM (Pulse Width Modulation), then driving a transistor (like a MOSFET) on and off rapidly. This approach saves energy and reduces heat.

Just like with DACs, a low-pass filter is needed to clean up the output before it reaches the speaker.

Speaker Output

The sound is produced by converting the electrical signal into motion, and that motion is used to drive a coil that's suspended from a diaphragm. Depending on your application, you might require different kinds of speakers, such as woofers for low frequencies or tweeters for high frequencies. High-fidelity systems tend to use both for improved sound quality.

In Summary

Audio design in embedded systems involves a series of careful trade-offs—balancing storage, processing power, and playback quality. Whether you’re building simple voice alerts or adding rich audio playback, understanding how digital audio works from input to output is key to making smart design choices.

How Meta (Facebook) is Building Its Metaverse Infrastructure

Introduction

When Mark Zuckerberg announced Facebook's rebrand to Meta in late 2021, he wasn't just changing a company name he was signaling a massive shift in digital infrastructure investment. The tech giant's ambitious vision for the metaverse represents one of the largest infrastructure projects in tech history, requiring revolutionary advancements in hardware, networking, and computing power. Let's explore how Meta is creating the foundation for its virtual universe and what it means for the future of digital interaction.

The Backbone: Computing Power and Data Centers

Meta's metaverse dreams begin with raw computing muscle. The company has dramatically expanded its data center footprint, investing billions in specialized facilities designed specifically for the computational demands of immersive 3D worlds.

Unlike traditional web services, metaverse environments require real-time rendering, physics simulations, and support for thousands of simultaneous users—all while maintaining low latency. To meet these demands, Meta has been upgrading its data centers with specialized AI processors and graphics hardware optimized for spatial computing.

The company recently unveiled its AI Research SuperCluster (RSC), which it claims is among the world's fastest AI supercomputers. This computing powerhouse isn't just for current AI tasks—it's being positioned as critical infrastructure for metaverse development, capable of training the massive models that will power everything from realistic avatars to intelligent virtual assistants.

Solving the Latency Challenge: Edge Computing and Network Infrastructure

For the metaverse to feel real, interactions must be nearly instantaneous. Even small delays between user actions and visual feedback can break immersion and cause physical discomfort. This creates a massive technical challenge that Meta is addressing through strategic investments in edge computing and network architecture.

The company has been quietly building out edge computing nodes closer to users, reducing the physical distance data must travel. Additionally, Meta has invested in subsea cable projects like 2Africa and Echo, expanding global internet backbone capacity to support the massive data transfers the metaverse will require.

Perhaps most interesting is Meta's work on "Project Aria," which explores how distributed computing between devices and the cloud can reduce latency. By splitting computational tasks—performing some calculations on headsets while offloading more intensive processes to nearby servers—Meta aims to deliver responsive experiences even with limited on-device processing power.

Creating the Interface: Hardware Development

While software and servers form the metaverse's foundation, hardware is where users will actually experience it. Meta's acquisition of Oculus in 2014 (for $2 billion) now seems prescient, giving the company a significant head start in VR hardware development.

The Quest headset line has evolved to become increasingly powerful while remaining affordable and wireless—crucial factors for mass adoption. But Meta's hardware ambitions extend far beyond current VR headsets. The company's Reality Labs division is working on multiple next-generation interfaces:

Lightweight AR glasses that overlay digital information on the physical world

Haptic gloves that let users "feel" virtual objects

Neural interfaces that can detect subtle muscle movements for more natural control

Spatial audio systems that create convincing 3D soundscapes

Project Cambria (now released as the Quest Pro) represented Meta's push toward higher-end mixed reality, incorporating eye tracking, face tracking, and improved passthrough technology—all essential components for creating presence in virtual environments.

Building the Digital Foundation: Software Infrastructure

Underpinning Meta's metaverse is a complex software ecosystem designed to handle everything from avatar creation to virtual economies. The company has developed several key platform components:

Horizon Worlds serves as Meta's social VR platform where users can create and explore virtual spaces. While still developing, it represents the company's vision of user-generated content driving metaverse growth.

Presence Platform provides developers with tools to blend virtual and physical reality, including scene understanding, spatial anchors, and interaction SDKs.

Avatar system allows persistent digital identities across Meta's apps, with increasingly realistic appearances and expressions.

Meta has also been acquiring companies with specialized metaverse technology, such as Within (VR fitness), Supernatural (VR fitness), and BigBox VR (social VR gaming)—integrating their innovations into the broader infrastructure.

The Interoperability Challenge

Despite investing billions in proprietary technology, Meta has publicly committed to metaverse interoperability—the idea that virtual worlds should connect rather than exist as isolated islands. The company joined the Metaverse Standards Forum alongside competitors like Microsoft, helping establish protocols for identity, payments, and virtual assets.

This approach recognizes a crucial reality: no single company can build the entire metaverse alone. By establishing open standards while maintaining ownership of key infrastructure components, Meta aims to influence the metaverse's direction while ensuring its central role in its development.

Ethical Infrastructure and Trust & Safety

Building metaverse infrastructure isn't just about technology—it's also about creating systems to ensure safety, privacy, and responsible use. Meta has established a $50 million XR Programs and Research Fund partly focused on developing ethical guidelines and safety features.

The company is developing tools like personal boundaries to prevent harassment in virtual spaces and content moderation systems designed specifically for 3D environments. These "trust and safety" elements represent critical but often overlooked infrastructure components.

The Economic Foundation: Payments and Commerce

A self-sustaining metaverse requires robust economic systems. Meta has been building financial infrastructure through several initiatives:

Horizon Marketplace enables creators to sell virtual items

Meta Pay (formerly Facebook Pay) provides payment processing

Digital collectible support allows for NFT displays on Instagram and Facebook

While Meta's cryptocurrency efforts (formerly Libra/Diem) faced regulatory challenges and ultimately shut down, the company continues exploring digital payment solutions that could power metaverse economies.

Conclusion

Meta's metaverse infrastructure represents one of the most ambitious digital projects in history, spanning hardware, networking, computing, and platform development. While significant technical, ethical, and business challenges remain, the company has demonstrated its commitment through unprecedented investment—reportedly over $10 billion annually.

The success of this massive infrastructure project remains uncertain. Questions about user adoption, regulatory oversight, and competition from other tech giants loom large. However, what's clear is that Meta isn't just talking about the metaverse—it's building the foundations it believes will support the next generation of digital experiences.

Whether Meta's vision of the metaverse becomes reality or evolves into something different, the infrastructure investments being made today will likely shape digital interaction for decades to come.
