Yes, it will be less than ideal for those sounds, but as long as it is not a majority of the file, it shouldn't be too bad. > In this experiment the intention is to retrieve the stream by http, > send PCM to stdout, pipe that to speexenc and save as a *.spx file. > > peter@dalton:~$ vlc --demuxdump-file=- \ > http://www.cbc.ca/quirks/media/2011-2012/qq-2012-01-21.mp3 \ > | speexenc qq-2012-01-21.spx > VLC media player 1.1.3 The Luggage (revision exported) > Warning: call to srand(1345820228) > Warning: call to rand() > Blocked: call to unsetenv("DBUS_ACTIVATION_ADDRESS") > Blocked: call to unsetenv("DBUS_ACTIVATION_BUS_TYPE") Those seem like odd errors, but I would dump the stream to a file (personally I always use mplayer, but VLC should work I suppose), then convert to wav (presuming mp3 is the native format of the stream in this case...) and then to speex. I am not sure it is worth it though, converting from one lossy format to another rarely works well. You tend to get really poor sound quality, and I doubt it would be worth it for the size savings you would get. If you really need it smaller, you may be able to convert it to a lower bitrate mp3, depending on what it is to start with.
