AudioGridder ~ Audio & MIDI Network Bridge

Posted by tom2tec on

AudioGridder is a network bridge for audio and MIDI that allows for offloading the DSP processing of audio plugins to remote computers. This can come in handy when mixing complex projects or running CPU intensive instruments.

AudioGridder Server runs on a computer hosting your effect and instrument plugins. On your workstation, on which you run your DAW, you use the AudioGridder FX or instrument plugin to access your plugin library over the network. The plugin is looking for available servers on your network and once connected allows you to create insert chains or load instruments. Midi and audio data from your DAW will be streamed over the network, processed on the server and streamed back.

CLAMPS ~ Common Lisp Aided Music Production System

Posted by tom2tec on

Clamps, short for “Common Lisp Aided Music Production System”, is a software system for realtime and non-realtime music production written in Common Lisp. It enables a seamless workflow between high-level structures to define musical processes all the way down to low level DSP definitions for sound creation including browser based interfaces for interactive work and control useable for live performances. In that respect it combines features of systems like OpenMusic, SuperCollider or the Pure Data/Max family of software.

SOF ~ DSP Firmware Infrastructure & SDK

Posted by tom2tec on

Sound Open Firmware (SOF) is an open source audio Digital Signal Processing (DSP) firmware infrastructure and SDK. SOF provides infrastructure, real-time control pieces, and audio drivers as a community project. The project is governed by the Sound Open Firmware Technical Steering Committee (TSC) that includes prominent and active developers from the community. SOF is developed in public and hosted on the GitHub platform.

The firmware and SDK are intended for developers who are interested in audio or signal processing on modern DSPs. SOF provides a framework where audio developers can create, test, and tune the following:

  • Audio processing pipelines and topologies.
  • Audio processing components.
  • DSP infrastructure and drivers.
  • Host OS infrastructure and drivers.

CamillaDSP ~ IIR & FIR Engine For Crossovers & Room Correction

Posted by tom2tec on

A tool to create audio processing pipelines for applications such as active crossovers or room correction. It is written in Rust to benefit from the safety and elegant handling of threading that this language provides. Supported platforms: Linux, macOS, Windows.

Audio data is captured from a capture device and sent to a playback device. Alsa, PulseAudio, Jack, Wasapi and CoreAudio are currently supported for both capture and playback.

The processing pipeline consists of any number of filters and mixers. Mixers are used to route audio between channels and to change the number of channels in the stream. Filters can be both IIR and FIR. IIR filters are implemented as biquads, while FIR use convolution via FFT/IFFT. A filter can be applied to any number of channels. All processing is done in chunks of a fixed number of samples. A small number of samples gives a small in-out latency while a larger number is required for long FIR filters. The full configuration is given in a YAML file.

Incudine ~ Lisp Music & DSP Programming

Posted by tom2tec on

Incudine is used to design software synthesizers or sound plugins from scratch, exploiting the expressive power of Common Lisp, without the constraints of using pre-built unit generators. It is also a compositional tool that produces high quality sounds, controllable at the sample level, while defining and redefining the digital signal processors and the musical structures on-the-fly.

foo_dsp_xgeq ~ Advanced Foobar2000 Equalization

Posted by tom2tec on

Foobar DSP based graphic equalizer.

Features:

  • 31 bands (1/3rd octave width)
  • boost / cut range of +-12 dB in 0.1 dB steps
  • master gain (can be set manually or automatically => prevents clipping for the most part)
  • minimum phase (=> no pre-echo)
  • approximates a smooth frequency response (=> no ‘steps’ between the bands)
  • import / export presets
  • mono and stereo mode
