Speex encoding in Java

Question

I have a .wav file and I am using JSpeex (latest version, i.e., 0.9.7) to encode it, but the encoding is not happening properly if anybody has worked on the file.

Answer 1

From here

You can find the following snippet:

When I used a different output-file format, specifically the .spx suffix, the encoding worked, and so did the subsequent decoding. The final decoded PCM WAV file then played successfully in QuickTime Player.

The original PCM WAV file I started with was "1-welcome.wav" from Sun's JavaSound demo program. If you installed Developer Tools, it's at: /Developer/Examples/Java/Sound/JavaSoundDemo/audio/

The encoding command-line:

java -cp jspeex.jar JSpeexEnc -w --verbose 1-welcome.wav welcome.spx

Because it's 11 KHz, you have to encode using '-w' (wideband), or it will fail with an obscure exception.

The decoding command-line:

java -cp jspeex.jar JSpeexDec --verbose welcome.spx welcome-pcm.wav

Hope this solves your problem.
