Author	Topic: spectrum analyser logic for accurate results
rafe Member	posted 05 February 2007 23:04 hello i am currious about why the spectrum analyser tool gives infinetly more accurate results if during the remove transient/ clicks/ inharmonic stage i leave the fader at its lowest possible setting, allowing all of the sound to pass through even though the sounds that i am processing are definetely pitched in nature. sitar samples - tuned percussion - tabla etc sorry i intended to post but i cannot upload until i get new compression software. thanks rafe IP: Logged
SSC Administrator	posted 06 February 2007 09:52 Perhaps you would be better off saving the first spectral analysis rather than proceeding to the step of tracing the fundamental and doing the quasi harmonic analysis. If you are setting the unvoiced fader to the lowest value, you are saying, effectively, that the entire file is "unvoiced" and that Kyma should not try to track the fundamental frequency. You could get the same results by saving the first spectral analysis and skipping the quasi-harmonic step. IP: Logged

SSC Administrator	posted 09 February 2007 09:56 It's not that it is more accurate or less accurate but that the quasi harmonic analysis is a harder task than the straight spectral analysis. The regular spectral analysis is essentially a bank of filters centered at fixed frequencies. When you do a quasi harmonic analysis, Kyma is trying to identify harmonics, even when they change frequency drastically. For your percussive sounds, it is probably best to stick with the regular spectral analysis. IP: Logged
