Dear Speex codec community:
I am working on conversion of voice files. I could not figure out how to use speexdec.exe 1.2.3 in piped mode in order to avoid the creation of the potentially large intermediate *.wav or *.pcm files. Any pointer to web or file of instruction is appreciated.
Attempt (one long command line, failed):
type d:\test.spx | "d:\speex 1.2.3\bin\speexdec.exe" - - | "d:\lame 3.97\bin\lame.exe" --preset voice - - > d:\test.mp3
Undesirable (working, 2 steps, create intermediate *.wav):
type d:\test.spx | "d:\speex 1.2.3\bin\speexdec.exe" - d:\test.wav
type d:\test.wav | "d:\lame 3.97\bin\lame.exe" --preset voice - - > d:\test.mp3
In contrast, conversion from mp3 to spx using speexenc.exe 1.2.3 and lame.exe 3.97 in piped mode works fine.
