Hi everybody, I need clarification about speex_bits_write function usage. There is an example usage of it. nbBytes = speex_bits_write(&bits, cbits, MAX_FRAME_BYTES); I examine the content of this function and which value should I set to MAX_FRAME_BYTE. In speexenc project, it is 2000 and in manual it is 200. For example, I set it to 200 but the length of bits->chars is 250 (bits->nbBits is 2000), is this right? If so, max_nchars gets 200 value becaus...

Thanks a lot for your explanations. Is it right I understand? if I've set SPEEX_SET_BITRATE to 16000(bps) this means that output is 16000/8=2000 bytes and I should set MAX_FRAME_BYTES and the length of cbits to 2000. Is it right? Maybe it is simple question but your answer is important for me, actually thanks a lot for your helps. Yasemin The last argument should simply be the size of your own buffer, i.e. it's there to make sure there's no buffer overflow and that...

Hello! I was using Speex all the time, and I am now moving to Opus. I had encapsulated the decoder a bit, I had the following cpp file: #include "StdAfx.h" #include "spxcodec.h" #define MAX_FRAME_SIZE 2000 #define MAX_FRAME_BYTES 2000 CSpxCodec::CSpxCodec() : enh(1), rate(8000) { } CSpxCodec::~CSpxCodec() { } void CSpxCodec::Init() { speex_bits_init(&bits); decstate = speex_decoder_init(&speex_nb_mode); speex_decoder_ctl(decstate, SPEEX_SET_SAMPLING_RATE, &rate); speex_decoder_ctl(decs...

Hi. I trying to encode PCM16 8000Hz stereo data to speex and put it into the .flv file format. But at the output I can hear only noise. What I doing wrong?

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
