Hi<br><br>I'd like to use the iirfilter in ffmpeg to filter out noise frequencies in my audio.<br><br>For this, I found the iirfilter.h in libavcodec<br><br>But i don't know how to use it properly, any tutorials / tips?<br><br>The first function seems a bit odd even.<br><br>ff_iir_filter_init_coeffs wants a void * avc which is something mysterious.<br><br>-mika<br> </div></body>
