The options panel controls a number of parameters affecting the analysis-re-synthesis engine. The default settings should prove adequate as a a starting basis.
Computed automatically in Voice and Instrument mode, the window size is set manually in Music mode. The window size determines the time frame base used to extract time-localized data in time from the incoming material. As general guidance, window size should be small for fast tempos and larger for slow music.
This determines how much extraction windows overlap during a given time-frame, in other terms, the update rate of the analysis for a given window size. Increasing this setting usually gives better results but also leads to more CPU resources being used, as more data has to be analyzed. The default setting of 4 is a good trade-off, but you can increase provided you have a reasonably fast machine and hear a noticeable difference.
Oversampling effects the sampling of the spectral representation of the source material. The quality difference achieved with oversampling is mostly noticeable with complex material with a broad frequency spectrum such as a full mix or a instrument such as the piano, but as the performance hit is quite high, you should only enable it if necessary, and if your hardware is sufficiently fast to handle the extra processing demands.
Sets the internal analysis/re-synthesis engine type to use.
Toggles transient processing on (default setting) and off. You can disable transient processing if you don’t need to treat transient separately, which will allow you to gain a little CPU. In this case however you will naturally not be able to control the transient level independently of other content.
