flacwrite - write out a FLAC-encoded audio file using flac

flacwrite writes FLAC-encoded audio files by piping data to the external flac binary

If you have a flac binary, and also the popenw mex extension, this routine allows you to write flac (free lossless audio coder)-format files as a drop-in replacement for wavwrite, accepting all the same syntax.

You can get popenw at http://www.mathworks.com/matlabcentral/fileexchange/13851
