- PEQ audio and import fixes. Band and preamp changes no longer click: filters keep their state across updates and the preamp is applied after them as a smooth ramp.
- Near-silent audio no longer drives the filters into slow denormal math.
- On low sample-rate files, a band above the file's frequency range is skipped instead of switching the whole EQ off.
- Imports match Equalizer APO more closely: LS/HS with a Q use APO's corner frequency, shelves without a Q use APO's default slope, comma decimals such as
-3,5are accepted, emptyNonefilter slots are skipped, and a shelf whose APO corner shift leaves 20–20000 Hz is clamped to the range instead of failing the import.
