About this build v0.2.18

What changed

Every track and the master bus now have real high-pass, low-pass, and parametric mid-band EQ.
The clean compressor provides threshold, ratio, attack, release, knee, input trim, output trim, and live gain-reduction display.
Neutral, vocal, guitar, drum, bass, and mix-glue presets remain conservative and bypassed until explicitly selected.
Approximate level matching offsets expected compressor reduction for fairer bypass comparisons.
All processors remain independently bypassable and persist per song without changing older saved mixes.

Known limitations

Level matching is an estimate based on a reference level, not loudness analysis of the song. Web Audio compressor behavior can vary slightly by browser. The Color slot remains reserved for the analog-style models planned for 0.2.19.

Keyboard

Space plays or pauses. Home stops and returns to the beginning. Shortcuts are ignored while a control or text field has focus.

License notice
