ESP8266Audio
Arduino library to play MOD, WAV, FLAC, MIDI, RTTTL, MP3
Arduino library for parsing and decoding MOD, WAV, MP3, FLAC, MIDI, AAC, and RTTL files and playing them on an I2S DAC or even using a software-simulated delta-sigma DAC with dynamic 32x-128x oversampling. ESP8266 is fully supported and most mature, but ESP32 is also mostly there with built-in DAC as well as external ones. For real-time, autonomous speech synthesis, check out ESP8266SAM, a library that uses this one and a port of an ancient format-based synthesis program to allow your ESP8266 to talk with low memory and no network required. ... -

Audiogen Codec
48khz stereo neural audio codec for general audio
AGC (Audiogen Codec) is a convolutional autoencoder based on the DAC architecture, which holds SOTA. We found that training with EMA and adding a perceptual loss term with CLAP features improved performance. These codecs, being low compression, outperform Meta's EnCodec and DAC on general audio as validated from internal blind ELO games. We trained (relatively) very low compression codecs in the pursuit of solving a core issue regarding general music and audio generation, low acoustic quality, and audible artifacts, which hinder industry use for these models. ... -

LMS plugins
Various plugins for Logitech Media Server
...Although Logitech has ended development of hardware devices, the project is still very active with lots of plugin released regularly. New hardware players can be added using PI devices and DAC board to build high-quality multi-room. I've created some extra plugins, especially to include new standard hardware/players to the LMS ecosystem: UPnP/DLNA (Sonos), ChromeCast and AirPlay. -

Minimal-GPSDO
A GPSDO with superior performance using a few cheap components
** To download everything, MinGPSDO.zip ** The design criteria for this GPSDO (GPS disciplined oscillator) were: ● Output 10MHz accurate to better than ±0.01Hz (1 part per billion) ● Use low cost components (cheapest GPS module, etc.) ● Be self monitoring so the accuracy can be guaranteed without reference to a better standard ● Require no tuning by the user ● Give feedback to the user of the current status ● If it can be done in software, do it in software The initial design... -

FabGL
ESP32 Display Controller (VGA, PAL/NTSC Color Composite, SSD1306, ST77
...It implements several display drivers (VGA output, PAL/NTSC Color Composite, I2C and SPI displays). FabGL can also get input from a PS/2 Keyboard and a Mouse. FabGL implements also: an Audio Engine (DAC and Sigma-Delta), a Graphical User Interface (GUI), a Game Engine and an ANSI/VT Terminal. VGA output requires an external digital-to-analog converter (DAC): it can be done by three 270 Ohm resistors to have 8 colors, or by 6 resistors to have 64 colors. Composite output doesn't require external components (maybe a 5Mhz low pass filter). ... -

...To use VitOS on your Raspberry Pi 4 Model B (1/2/4/8GB version), just download the image file and write to the micro SD card with dd or other applications. Then plug in the micro SD card to your Raspberry Pi4. You can use iOS app and Android app named "VitOS Manager" to manage the VitOS. VitOS V1.0 supports USB DAC as audio output device. You can connect your USB DAC to the USB port on your RPi4 board. With VitOS Manager, you are able to install Roon Bridge to the VitOS. Then you can discover the RPi4 board with Roon apps and play music.

The plugin is a combination of two libraries - SSRC and SOX, the first one is fixed, and the other is floating point. The main purpose is to "override" the LPF(s) inside of the DAC by upsampling (relatively) low sampling rate frequencies (44.1k, 48k), assuming the software can do it much more accurate. It should be noted that the component, allows to compare two main resampling techniques with the same parameters. The user interface is built to be intuitive and to allow to maximize the control and ability to adjust the parameters to the user's personal taste.

CASMR CSS
Source Code content for Open Source packages used by the CASMR CSS
Source code content for Open Source packages used by the CASMR Stream Server (CSS). The code download portion of the Digicipher II system has been extended outside of the DAC 6000 and is now provided by CASMR 100. The code download functionality can be delivered simultaneously by both the DAC 6000 and CASMR 100. This is made possible by the introduction of the CASMR Stream Server, which is comprised of the RADD 6000 and data stream server functionality. The CSS multiplexes the DAC 6000 and CASMR 100 control streams and code object streams into a single combined out-of-band transport multiplex so the terminal can acquire them. -

CASMR CDL
Source Code content for Open Source packages used by the CASMR CDL
Source code content for Open Source packages used by the CASMR Code Download (CDL). The code download portion of the Digicipher II system has been extended outside of the DAC 6000 and is now provided by CASMR 100. Code Download signaling or provisioning instructions are delivered through the out-of band control channel for DCII terminals. Code objects are carouseled either on the out-of-band control channel, on a specified in-band stream, or defined IP Multicast. The provisioning commands provide enough information for the terminal to acquire the code download data stream, load, and then activate the code object.
