Ableton/Live/UG/29 Audio Effect Reference/26 Multiband Dynamics/02 Interface and Controls
- High and Low switch those bands on; with both off it works as a single-band device using only the Mid controls. The sliders below them set the crossovers: at 500 Hz and 2000 Hz the bands are 0–500 Hz, 500–2000 Hz and above 2000 Hz.
- Each band has an activator (off bypasses its processing and gain) and a solo button. Input knobs set each band's level before processing, Output knobs after.
- In the display, large bars show each band's output and small bars its input; with no processing the input meters line up with the tops of the output meters. The scale is in dB.
- Thresholds: the blocks at the left and right of each band are the levels below the Below threshold and above the Above threshold. Drag their edges sideways to move the thresholds.
Cmd (Mac) / Ctrl (Windows) — same threshold on all bandsOption (Mac) / Alt (Windows) — Above and Below together for one bandShift — finer steps
- Ratios: drag up or down in the middle of a block to make that level range louder or quieter; the same modifier keys apply, and double-click resets.
- Above the Above threshold: down is downward compression, up is upward expansion.
- Below the Below threshold: down is downward expansion, up is upward compression.
- The column to the right of the display also shows the values. Buttons T, B and A switch it between Time (attack and release), Below (threshold and ratio) and Above (threshold and ratio).
- Attack and release:
- Above thresholds — Attack is the time to full effect once the signal rises past the threshold; Release the time to recover after it falls back
- Below thresholds — Attack is the time to full effect once the signal drops below; Release the time to recover after it rises again
- Soft Knee — processing starts gradually near the threshold
- RMS/Peak — Peak reacts to short peaks; RMS waits until the level has stayed past the threshold a little longer
- Output — overall output gain
- Time — scales all attack and release times together
- Amount — scales the strength of all processing; at 0% every ratio is effectively 1
