In the resampling preferences, is your sinc function set to best quality?When you change the pitch, the audio quality gets notably worse.
Yes I did. It was utmost easy to set the +/- values on the self explanatory Audacity.Did you installed Audacity to check the difference?
My ears are probably not as selective as yours... To get a well documented advice I will do two things:My method for what? /.../simply notice the quality difference, I have not compared the audio wave or signal visually at all.
Looking at analog waveforms will tell you nothing about distortion, intermodulation and granularity ; the only way to evaluate a pitch shifter is to analyse its digital output with a spectrum analyser. I guess VLC can store the pitch-modified stream sent to the pc's D->A converter, something Audacity allows.I'll try to record the VLC playback with the effect included, losslessly
Hi, thanks for passing by. It's just that the new pitch shifter feature in VLC, when it changes the pitch, it "messes up" the track, because I can clearly hear that the sound quality gets notably worse. I don't know what it can be, may be the process is lossy. I think it should use a better plug-in or whatever it is that adds this feature. I know it's lossy because when I change the exact amount of pitch using Audacity, the sound quality is just as good as the original track, but of course with the modified pitch.
I spent some hours doing the research to write my last message up there, where I compare the sound waves of the resulting modified track using Audacity and VLC. By the way, when you change the pitch in Audacity, it takes like 1-2 seconds (well, since this is a CPU process, it depends on the power of your CPU) of processing, it's not a on-the-go feature, like VLC.
May be that's the problem?
May be you should use a process that is more CPU demanding but the result is almost lossless?
