Constant noise in the background in realtime data
Hi everyone,
Our team is working on a realtime voice communication application. We are using openAL 1.1 to capture the samples and then encode them using speex. On the remote machine we decode the samples and play them using openAL again. Capture and play formats for the samples is AL_FORMAT_MONO16 and frequency is 22050. we are using wide band encoding/decoding.
The encoding sample frame buffer size is returned by speex as 320, on both ends ( speex_encoder_ctl(m_poSpeexState, SPEEX_GET_FRAME_SIZE, &nFrameSize) ).
Coming to the problem, when I play the sound I get a high pict...

problem with compression and decompression
...ce, I am attempting to
read a frame, and compress, then uncompress, and then playback that frame
before I move on to the next frame.
While initializing the device for reading the sound information, I give it
the following parameters:
22050 (which is the frequency with which to take sound samples)
AL_FORMAT_MONO16 (which is the OpenAL format in use)
BUFFERSIZE (which is 1024, the size of the frames which I read)
As for the arguments for "Compress()", pData is the ALchar pointer which
contains the data. iFrameSize is the integer which will store the number of
bytes actually written to the compresse...

compression/decompression functions.
