general question about audio processing
I'm working on a project were a noise canceller solution is required to improve the audio catched by a microphone.
On the BM62 Bluetooth module, the built in noise canceller and acoustic echo canceller is performing well and I'm wondering how can I do a similar job with a DSPic, or a dedicated IC... I found echo cancellation library but harder to find something about noise cancelling.
Does anyone of you got some experience of noise cancelling anc echo cancelling with a DSP?
I've tried a TLV320AIC3254 wich is a codec with programmable DSP on it, but the performance are not very good...
thanks for your help
