Originally posted by tubenut The problem isn't the sines so much as some nearly-imperceptible clicks that occur in the sample, due to slightly innacurate tape editing or something. You have to look at a spectrogram to tell they're even there. Run the sample through Vorbis at 160, and blips occur at the places where the clicks were.
Originally posted by Garf Hmm, is this normal Vorbis or my tuned mode?
The tuned modes should handle postecho, and produce no more postecho than they produce preecho, which would make the postecho inaudible because the preecho should then be way worse because of the way the hearing works.
If it still happens with my tuned mode, my best guess is that the small block trigger for postecho is not set sensitive enough.
Originally posted by niktheblak Dibrom's --alt-preset standard actually sounded rather good. I don't think I could ABX it. As usual, MPC was annoyingly transparent.
And Dibrom, I think you may be right about that ClearVoice thing. The sound of harpsichord (and speech) is based solely on very special harmonic beaviour and since human hear is extremely trained to detect harmonics, increase in bitrate might be in order.
ClearVoiceDetection CVD(still German): During activity of vocals (especially vowels) or similar harmonic signals higher resolution of quantization is assigned to the belonging spectral bins. This procedure will fix some problems of the psychoacoustic models during changes of the base frequency of harmonic signals.
