Ecasound is a software package designed for multitrack audio processing.
It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording, signal recycling, and automating audio processing tasks.
Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. As most functionality is located in shared libraries, creating alternative user-interfaces is easy.
A versatile console mode interface is included in the package.
Key Features
- Multitrack audio recording, playback, mixing and format conversion.
- Console interface supporting interactive operation and scripted processing.
- Real-time audio processing with automatic adjustment of buffering parameters.
- Support for ALSA, JACK and LADSPA effect plugins.
- Apply effects including amplification, panning, equalisation, compression, noise gating, delay, reverb and pitch shifting.
- Route and mix audio channels, with support for signal recycling.
- Control effect parameters using oscillators, linear envelopes and MIDI continuous controllers.
- Use ecaconvert for batch audio conversion, ecanormalize for volume normalisation, ecafixdc for DC offset correction and ecalength for audio file information.
- Use ecaplay for playback and ecasignalview for monitoring audio signal levels.
- Control the processing engine programmatically through the Ecasound Control Interface.
