Damien, Your WAV file probably isn't in standard PCM format. Did you know that WAV files can contain all kinds of formats, including MP3 and even Speex (IIRC)? But most software that reads WAV files only handles plain PCM format, so WAV files using other formats are of limited use. Typically an app will need to use the Windows ACM to decode them, and have a suitable codec installed on the system. Here's an example WAV file that will work with speexenc: http://www.speex.org/samples/audio/wb_male.wav Tom "Damien Guiserix" <damienguiserix@gmail.com> wrote:> > Hello, > > I'w trying to encode a wave file using speex beta1.2 and cygwin > > i installed speex following the manual instructions > but when i want to encode the file using > > speexenc -w francais.wav test.spx > > the software answer that only PCM encoding is supported > > Is somebody can explain me what's wrong? > > Thanks > > Damien
