5.1 channel analog audio processor

In this project, we developed a 5.1-channel analog audio processor using PT2322 IC. PT2322 is an inexpensive analog audio processor introduced by Princeton Technology Corporation. It contains 6-channel individual channel attenuators, a 3-way tone control system for front-end speakers, and a 3D audio simulation system. 

In this design, we combine PT2322 with Arduino Nano and interface it with PC/embedded computing boards through a USB port. Native GTK UI application provides to control all functions of the PT2322 IC.

The Arduino Nano can directly plugin to the PT2322 module. There are three push buttons on the panel itself to control the volume and mute the audio.

To reduce the cost and minimize the PCB size, we use both SMD and through-hole-type components in this PCB. The dimension of the PCB is 59mm × 60mm. The PCB of this module can directly order from the PCBWay project page. Using the PCBWay service, you can order high-quality PCBs at low prices. Use the PCBWay online quote tool for pricing and more details.

The Arduino firmware in this project is developed using PlatformIO. The host-side control application is written using GCC C. This UI application can be compiled and run on any Linux/GTK compatible board like PCs, Raspberry Pi, Orange Pi, BeagleBone Black, etc. All communication between the host and the module is performed through the USB UART interface provided by the Arduino Nano board.

At the prototyping stage, we test this board using an ASUS Xonar SE 5.1 channel soundcard and Creative Inspire T6300 - 5.1 analog speaker system. The above setup delivers clean audio output without any noticeable distortion. 

In PT2322, the tone control system applies to front-end channels only. The remaining channels work independently from the tone control system. This is a design limitation of the IC. From our experience, this can sometimes adversely affect the surrounding listening experience.

The PT2322 has a 3-way tone control system that allows bass, mid-range, and treble control over a range of -14dB to +14dB. A 6-channel attenuation system provides up to 15dB attenuation per channel. All these controls divide into 15 steps. The master volume control can use to adjust attenuation from 79dB to 0dB in 80 steps.

This audio processing module is an open-source hardware project. All the design files, source codes, and compiled binaries are in the project repository at github.com.

"Czar" Lisp keyboard & "Marilith" SBC? ideas

Some retro-heavy inspirations for my own Lisp Keyboard for the 21st century. Less leaning for the cooler colors and more towards getting hints for the specific keys, their styling & their placement.

As for the "Marilith" computer build I envision the above keyboard accompanying, I would focus towards using either a existing RISC-V SBC, a BeagleBone Black Wireless pack or some custom mini-kit that uses RISC-V as its processor basis. And yes, I am heavily inspired by the eighties soviet mockup for the Sphinx box and I/O devices, kinda like how the Pentagon felt cool and quirky for a ZX Spectrum clone.

I do not need much in processing specs (RAM & on-board storage should reach 4+GB-48GB respectively), as it is a mostly experimentation & research-driven home computer build project to dive into low-range computation whilst staying both aesthetically-pleasing and transparent computation-wise. I could use something Apple M1-ish or whatever lightweight Microdot Linux-like bindings for my command-line interface-heavy uses for it but it should mostly be a testing and development bench for tinkering and educational purposes on my end. Running minuscule operating systems like ZealOS, XXIIVV's Parade, MINIX3... and indeed develop some of my own derived from history and into the imagination beyond.

So yeah, I expect getting there financially by my 25th birthday, on August 1st this year, but I will get you some more information onto those "Servitor"-like baby steps project in due time.
