Once all processing is done, the audio data is posted to the input queue of the playback device. Once a message arrives, it's passed through all the defined filters and mixers of the pipeline. The processing thread waits for audio chunk messages to arrive in the input queue. After this the capture thread returns to reading the next chunk of samples from the device. At the end, the chunk of samples is packed as a message that is then posted to the input queue of the processing thread. If resampling is enabled, the audio data is sent to the resampler. It then converts the samples to 64-bit floats (or optionally 32-bit). The capture thread reads a chunk samples from the audio device in the selected format. This chart shows the most important parts: There is also a supervisor thread for control. The processing queue waits for audio messages, processes them in the order they arrive, and passes the processed audio via another message queue to the playback thread. Each message consists of a chunk of audio with a configurable size. The capture thread passes audio to the processing thread via a message queue. One thread handles capturing audio, one handles the playback, and one does the processing in between. The audio pipeline in CamillaDSP runs in three separate threads. The IIR filtering is heavily inspired by biquad-rs:.

The goal of CamillaDSP is to provide both FIR and IIR filtering for Linux, Windows and macOS, to be stable, fast and flexible, and be easy to use and configure. For Linux the best known FIR filter engine is probably BruteFIR, which works very well but doesn't support IIR filters.

This functionality is available in EqualizerAPO, but for Windows only. The purpose of CamillaDSP is to enable audio processing with combinations of FIR and IIR filters.

Usage example: crossover for 2-way speakers.

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

The processing pipeline consists of any number of filters and mixers. Alsa, PulseAudio, Jack, Wasapi and CoreAudio are currently supported for both capture and playback.

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