Hi, Tank you for your reply. I have tried the sample programs given the manual and done encoding and decoding a wave file. That is working fine. I have already read the manual and API reference. But this problem did not occured with the wave file encoding/decoding. While capturing the data from MIC and encoding/decoding is giving this problem. Thanks and Regards, Vijender Reddy, -----

Look, how about you start from the testresample.c file? Oh, and you seem to be reading 320 samples at a time and processing 640, so that can't be good (and even beyond that your code is wrong for other reasons).

In R's sprintf() if any of the arguments has length 0 the function aborts. E.g., > sprintf("%d", integer(0)) Error in sprintf("%d", integer(0)) : zero-length argument > sprintf(character(), integer(0)) Error in sprintf(character(), integer(0)) : 'fmt' is not a non-empty character vector This comes up in code like x[nchar(x)==0] <-

...n and sample code's. I am facing audio glitches when encoding - decoding PCM data. The encoder and decoder procedures are copied below. What about the lookahead size ? how shouw we apply it in encoding stage ? thanks in advance bool SpeexEncoder::EncodeData(char * inBuffer, int inSize, char * outBuffer, int outMAXSize, int* outSize) { if(!m_Initialized) return false; // Copy data into the local buffer memcpy(m_pBuffer + m_BufferSize, inBuffer, inSize); m_BufferSize += inSize; // check if we have enougth data for the encoder, if(m_BufferSize < m_FrameSizeInBytes )...

Be aware that inlen is an in/out parameter. It tells you how many samples the resampler read. That number can be smaller than what you passed -- in which case it means you need to buffer them and give them to the resampler again in the next call.

Hi Randy, thanks for the reply. So, suppose I encode an audio buffer (8000 kHz, MONO, float) of 640 PCM frames. In output I have 4 speex frame of 20 byte

...ext, I tried a bitcode file whose first line was "target triple = "i686-pc-linux"". llc gave me the following error: FIXME: This code needs to be updated for changes in the CodeEmitter interfaces. In particular, this should set BufferBegin/BufferEnd/CurBufferPtr, not deal with OutBuffer! This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Any help would be appreciated. Thanks, Jon

Hi, in a VoIP application, the endpoint A send speex payload to B. B doesn't know how A acquire audio, it only know that the channel is narrowband so, how can B know the size of the output buffer to pass to the speex_decode()? Thanks, Daniele.
