Press Release 23 November 2001: M-Pack 1 WAV file processing toolbox for MATLAB® now shipping

M-Pack 1, the first in our new M-Pack product line of audio-related MATLAB® toolboxes is now shipping. M-Pack 1 is a collection of MATLAB functions for processing (uncompressed PCM) WAV files of arbitrary size, significantly extending the in-built WAV handling capabilities of MATLAB. Key features include: support for arbitrary bit resolution (between 2 and 32, including a distinction between valid bits and container size); support for Microsoft's WAV_FORMAT_EXTENSIBLE file format for multichannel (and high bit-depth) WAV files; option to apply various forms of dithering when writing data to WAV files; chunk-by-chunk (disk-based) WAV file effects processing; WAV file sample rate conversion between all sample rates commonly used in digital audio; WAV file playback (via the Windows default soundcard) from within the MATLAB environment.

M-Pack 1 is a "conventional" MATLAB toolbox, in that it is designed to be used wholly within the MATLAB environment (by contrast, our WaveWarp Audio Toolbox for MATLAB provides a real-time audio streaming interface to MATLAB from the outside).
