...ders to standart distribution packet (I'll send this to you if you wish). It will help for many developers. But... there was another problem. I think many pepople was ask you about that problem. Yes. It's DLL static variables named "speex_nb_mode", "speex_wb_mode", "speex_uwb_mode". There is no declaration of it in DLL file. Somebody give a solution: instead of this data use "speex_lib_get_mode". But there is NO declaration of this function in DLL file (I tryed to find it in latest available version for Win32 too). I was need to modificate speex source and re...

just to check that I've got everything right. the encoder allows as input - mono only - 8 or 16 bits as floating point numbers (without scaling to 1.0). floating-point wavs (IEEE) will also work, but it's better to scale them to something like 8000. - any sample rate (should be set with speex_encoder_ctl), but prefered are 8/16/32 kHz. but what modes should I use for a given rate? also -

hello, i switched to use the encoder.processData() and encoder.getProcessedData() of jspeex. however it looks to me like a memory leak ... memory usage is increasing very fast and there is no visible stop ... after about five minutes java.lang.OutOfMemory occurs. I think it must be the jspeex component, because before i added jspeex to my app usage was constant at about 5mb. is it possible
