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.

Pipewire ~ Linux Multimedia Processing
PipeWire is a project that aims to greatly improve handling of audio and video under Linux. It provides a low-latency, graph-based processing engine on top of audio and video devices that can be used to support the use cases currently handled by both PulseAudio and JACK. PipeWire was designed with a powerful security model that makes interacting with audio and video devices from containerized applications easy, with support for Flatpak applications being the primary goal. Alongside Wayland and Flatpak, we expect PipeWire to provide a core building block for the future of Linux application development.

AGS ~ Advanced Gtk+ Sequencer
Advanced GTK+ Sequencer is intended to use for music composition. It features a piano roll, as well a synth, matrix editor, drum machine, soundfont2 player, mixer and an output panel.
It’s designed to be highly configurable, you may add effects to its effect chain, add or remove audio channels/pads.
You may set up a fully functional network of engines, therefore exists a link editor for linking audio lines.
In conjunction with ags you need a realtime kernel and alsa support. `ags` uses conditional locks to keep several threads in sync that’s why you need at least a preemptible kernel.
Features:
- save or open Advanced Gtk+ Sequencer XML files with XPath support
- add or remove audio engines with adjustable audio channels and pads
- link channels with property dialog
- output panel, mixer, drum and matrix sequencer, soft synth and audio file player
- piano roll with basic notation editing supporting copy & paste
- adjustable BPM
- LADSPA, DSSI and Lv2 support
- export to WAV, FLAC, OGG and others
- multiple sinks like Pulseaudio, JACK, ALSA and OSS
- automation editor
- waveform editor with copy & paste
- capture sound with AgsAudiorec machine
- MIDI instrument input
- import/export to Standard MIDI Files
- OSC content format support
- OSC server for remote control and monitoring

ANMP ~ Another Nameless Music Player
ANMP aims to be a versatile but lightweight audio player, just as the other hundred thousands out there. It is written in C++11. As being only a frontend, ANMP itself doesn’t know anything about audio formats and how to decode them. That’s why it uses 3rd party libraries to decode them. By using VgmStream, GameMusicEmu, LazyUSF and supporting looped songs natively, ANMP is esp. suited to play various audio formats from video games. Moreover it supports Looped Midi Tracks.
Main Features:
- muting multichannel audio files
- gapless playback (for most streamed audio formats)
- arbitrary (forward) looping of songs (i.e. even nested loops)
- synthesizing MIDI files using fluidsynth
- multi-channel audio rendering
- overlapping notes do not kill each other
- unrolling looped MIDI tracks
- volume response compatible to N64’s software synth
- supports an IIR lowpass filter compatible to Rareware‘s N64 games (Conkers Bad Fur Day, Jet Force Gemini)
- support for cue sheets
- support for audio normalization based on EBU R 128
- exposes basic commands via D-Bus

Pulseaudio ~ Linux Crossover Rack
Pulseaudio Crossover Rack is a program to design and implement multi-way speaker crossovers using any linux powered computer with a multi-channel sound card and a running desktop environment which uses Pulseaudio as it’s sound backend. It also uses a set of LADSPA plugins, namely ladspa-t5-plugins for the heavy lifting of DSP/audio processing. It’s written in python3 and uses QT as the windowing toolkit.
