A cross-platform toolbox for simultaneous recording, processing and playback of multichannel audio in Matlab. Main features:

• Optimised for multichannel audio recording and playback
• Support of 64 and 32 bit Matlab on Windows (Linux coming soon)
• MEX functions return control to Matlab immediately after starting recording/playback thread and could be terminated by the user at any time
• Supported audio interfaces: ASIO, WindowsAudio and DirectSound (on Windows) and ALSA/JACK (Linux)
• Audio device settings could be stored in *.xml files allowing flexible change of configurations
• Playback file formats: WAV, OGG and AIFF with 16, 24 and 32 bit resolution
• Recording file format: 32-bit floating point WAV (one file for each channel)
• Direct recording and playback to/from Matlab matrices
• Real-time fast convolution of input and output signals using partitioned convolution technique
• Real-time filtering of input and output signals using user-defined IIR filters
• Multithreaded disk read/write operations.

The software is written in C++ using open source JUCE and FFTW libraries.
