Ahoj, zkouším FLStudio9 XXL Producer Edition a zkouším v nastavení-Audio Vybrat metodu interpolace.

Sice zkouším rozdíl mezi těmito interpolacemi(název a caption v programu)
Linear: fast-low quality
6-point hermite - fast,average quality
64point sinc - slow, good quality
128....-very slow, goood quality
256 ... very slow, very good quality
512 ... very slow ,best quality
u 128 a vyšší vyskakuje ještě popup, "že to more accurately hear song as will be rendered... It is also SLOW AS HELL)
V nápovědě jsem se dočetl

Interpolation - is the process of smoothly creating changes in sample data when the system is called to 'invent' intermediate volume levels between any two known sample points. This is necessary when samples are transposed from their original pitch to avoid 'quantizing' and/or 'aliasing' noise, so the benefits of higher quality interpolation will only be useful for transposed sounds.

There are two independent locations where interpolation method can be set. Here in the Audio Settings the interpolation method affects the 'live' audio quality (and CPU load). The other interpolation setting is found on the export dialog and affects audio file quality (and render time). The options are the same for both locations, they are:

Linear interpolation provides the lowest CPU hit with basic linear averaging between samples, however this may result in aliasing (high frequency noises) when samples are transposed far from their original pitch. We recommend linear settings for most live mixing situations.

6-point hermite is the fastest interpolation method and so is suitable for 'real-time' playback, providing superior quality to 'linear' interpolation. If you have a fast PC, use this method during critical mixing sessions.

64, 128, 256, 512-point sinc interpolation methods provide, increasingly, the highest quality interpolation, at the expense of CPU load. Anything above 6-point Hermite is not suitable for live-playback (perhaps one day when we have 32-core 10 GHz CPUs). So why are these methods available? So that if someone requires the highest quality live interpolation they can have it...don't believe us?, turn on 512-point sync and watch your PC grind to a stuttering halt next time you transpose a sample...don't say we didn't warn you!
