Dear all,
Wav files usually contain PCM data, but they can also work as containers of other formats, such as compressed audio, for instance A-Law, Mu-Law, ADPCM or even MP3 or FLAC. There are over 200 registered format tags, however Scilab only accepts 2, integer PCM and 32 bit float PCM.
It would be useful to have sample files to test, analyze and experiment with, particularly if someone would like to expand the support of Scilab's wadread. However, most audio software, including the open source Audacity, only creates PCM wav files. Other formats such as MP3 are exported under their own non-RIFF extension.
I can export to ADPCM, A_Law and Mu-Law wav files using an old (non free) application calledCool Edit 2000
Is anybody aware of a free software capable of exporting more formats to the wav container?
Regards, Federico Miyara
