Speex dev - Apr 2010 - Regarding problem with encoding / decoding

Hi,

I am new to speex library. I am doing project in VC++. My project details are,
I have to capture voice from mic and encode it  then decode  and play.
I am capturing the voice and storing in a buffer from there i am reading frame
by frame ( 160 bytes) . These bytes i am converting to short int then calling
speex_encode-int(). The output buffer i am passing to doder speex_decode_int()
function. with out encode and decoding the program working perfectly i am able
listen the voice.

After decoding if i play the data in the buffer. I am not able to listen the
voice , noise is dominating the voice.  I am hearing like the voice itself
merged with noise. I used denoising and ADC functions but no use. Please help
me..


Thanks and Regards,
Vijender Reddy,

Start from the sample encoder/decoder in the manual.

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,
