Ableton/Live/UG/29 Audio Effect Reference/11 Delay

- Delay has a separate delay line for each stereo channel, a band-pass filter, and LFO modulation.
- Delay Time Mode — Sync (beat divisions) or Time (1 ms to 5 s)
- In Sync, numbered buttons set the delay in sixteenths; 4 is one beat. Offset sliders move each delay slightly early (negative) or late (positive), for swing.
- Stereo Link — one delay time for both channels; Offset stays separate
- Feedback — output fed back into each channel's own delay line; left and right do not cross
- Freeze — loops whatever is in the buffer at that moment and ignores new input until released
- Filter — band-pass before the delay. Drag in the display: horizontal for frequency, vertical for width; or use Freq and Width.
- An LFO can modulate delay time and filter frequency, from chorus to chopped glitches. The LFO Controls toggle expands the full LFO section; its LED flashes at the LFO rate.


- Delay — LFO amount on delay time; Filter — on filter frequency
- Rate mode — Rate, Time, Synced, Triplet, Dotted, Sixteenth
- Wave — Sine, Triangle, Ramp Up, Ramp Down, Square, S&H, Wander; Morph reshapes it
- Smoothing, for when the delay time changes during playback:
- Repitch (default) — pitch bends like an old tape delay
- Fade — crossfades old and new times; gradual changes can sound granular
- Jump — switches at once, possibly clicking
- LFO modulation sounds different in each mode.
- Ping Pong — bounces the delay between left and right
- Dry/Wet — set to 100% on a return track
- In the context menu or the title bar's Show Options menu:
- Hi-Quality — better interpolation in Repitch and Fade, and tape-style smoothing of time changes in Repitch
- Dry/Wet - Equal-Loudness — keeps perceived loudness steady across the Dry/Wet range, so 50/50 sounds as loud as either end
- Two starting points from the manual.
- Stereo Link on, Sync time 6, Feedback 50%
- Filter on at 2.86 kHz, Width 2.50
- LFO S&H at 0.93 Hz; Delay 66%, Filter 19%
- Fade smoothing, Ping Pong off, Dry/Wet 50–80%
- Stereo Link off; left 12.0 ms, right 30.0 ms; Feedback 0%
- Filter on at 2.56 kHz, Width 8.50
- LFO Triangle at 0.65 Hz; Delay 58%, Filter 0%
- Repitch smoothing, Ping Pong on, Dry/Wet 45–65%
