Convert Speex (.spx) files made by Recorder to mp3
asked 2014-09-23 18:16:02 +0200
Hi,
I have sound file recorded by Sailfish os native app Recorder (earlier version than newest 23.9.2014). Format is Speex (.spx). I would like to convert that file to mp3. If You know good tool (and You know that it's working) for that for linux, osx or windows please share.
Looks like difficult one.. Is there some special parameters used in Recorder with Speex?
Tried:
http://jspeex.sourceforge.net (only tried http://sourceforge.net/projects/jspeex/files/player/2.2-0.9/)
Audacity 2.0.3 with FFmpeg-library (http://wiki.audacityteam.org/wiki/OGG)
Can't be so difficult.. x)
Does this question belong here? Not sure what the Sailfish/Jolla community can do about what formats osx can play.

Depending on how it is built, you could also convert it directly to an mp3, but at least with Debian, ffmpeg is compiled without mp3 support.
