Hello, I am a newbie and wanted to know if a speex preprocessor, such as a DENOISE, can be used with other encoders such as AAC. We are developing video cameras using speex codec for encoding and decoding audio when placing calls. We also stream live audio/video files out of the camera and use AAC encoder for that as the server that we stream to supports only AAC. But, the noise level is high even when the environment is quiet. Hence, would want to implement a de-noise preprocessor from speex to do the same. Will speex pre-processor work when using different encoders? Please do let me know. Thank you, Ankhit -------------- next part -------------- An HTML attachment was scrubbed...

Hello Tristan, Thank you. But I am using libspeex library. Does the speexdsp library be included in it? Or it needs to be installed separate. Appreciate the help.
