...d I have a rough idea how to decode a raw stream. (I'm assuming the sampledec source works with raw speex audio samples and doesn't handle ogg containers.) I've also managed to compress a wave file and output a .spx file using JSpeex and the following Groovy code: AudioInputStream ais = AudioSystem.getAudioInputStream(new File("16Bitprompt.wav")); AudioFormat wavFormat = ais.getFormat(); AudioFormat speexFormat = new AudioFormat(SpeexEncoding.SPEEX_Q5, wavFormat.getSampleRate(), -1, // sample size in bits wavFormat.getChannels(),...

Is There any intension to deal with mixing two or more streams encoded with "speex". Most voice wise applications (such as conference) need this feature.
