14. The introduction of the 8 filters for KA17
There are 8 different filters built in the KA17 for your preference. Filters are the sound effects born with the chip, which only has slight adjustments for the sound. Here are some introductions to some filters. These are only for reference since actual listening also has something to do with the matched device.
MINI: Minimum phase (default)
Conventional minimum phase filter. No front ringing, but very large rear ringing.
FAST A: Linear phase fast roll-off apodizing
Linear phase filters incorporating special window functions to optimize transient response - Theoretical
FAST: Linear phase fast roll-off
Traditional linear phase filter. Symmetrical ringing, audio DACs from 20 years ago were mainstream defaults for this filter.
FAST R: Linear phase fast roll-off low ripple
Conventional linear phase filters that reduce some ripple.
SLOW: Linear phase slow roll-off
Conventional linear phase filters with almost no filtering
MINI F: Minimum phase fast roll-off
Approximates a "conventional minimum phase filter", trading ripple for faster roll-off.
MINI S: Minimum phase slow roll-off
This filter is recommended if the song is at a high sample rate, e.g. ≥ 176.4kHz.
MINI S D: Minimum phase slow roll-off low dispersion
The relatively most natural sound. Note: Natural does not necessarily sound good, especially with poor quality recordings.
