how to fix high freq noise?
Hi Masakazu, I have reproduced the Speex high frequency noise issue on a Blackfin 537 by sending 'silence' into the Speex fixed point encoder. By recording the Speex decoder output and plotting the spectrum using Audacity the following two frequencies. 1596Hz at -31.3dB 3200Hz at -48dB These two frequencies are present in both Narrow Band and Wide Band modes. I've tried a number of different configurations and these two frequencies are always present (quality set to 10 or default, the complexity set to default, perceptual enhancement turned on or off). I have not determi...
