Add delay in 4 steps:
- Select audio (voice, guitar, drum, or full mix)
- Open Effect → Delay and Reverb → Delay
- Set delay type, delay time, and number of echoes
- Click Apply
What Is Delay?
Delay records your signal and replays it after a time gap to create audible repeats. Short values create thickening or slapback, while longer values create rhythmic echo trails. Audacity's Delay effect adds multi-echo control over timing, decay, pitch behavior, repeat count, and whether the track duration extends to contain the full tail.
How to Add Delay in Audacity
Step 1: Select Your Audio
Select the clip or region to process, or press Ctrl A ⌘A to target the whole track.
Step 2: Open Effect > Delay and Reverb > Delay
Open Audacity's built-in Delay effect from the effects menu.
Step 3: Choose Delay Type, Time and Number of Echoes
Pick the timing pattern and tune the repeat spacing, level behavior, and count to fit your rhythm and style.
Step 4: Apply
Preview if needed, then apply. For long tails, enable duration extension so echoes are not truncated.
Delay Settings Explained
Delay Type (Regular / Bouncing Ball / Reverse Bouncing Ball)
Regular keeps spacing constant, Bouncing ball compresses gaps over time, and Reverse bouncing ball expands them.
Delay Level per Echo (dB)
Negative values fade each repeat, zero holds level, and positive values can quickly clip. Start around -6 dB for natural decay.
Delay Time (seconds)
Controls the main repeat interval: around 0.08–0.12 s for slapback, 0.25–0.5 s for rhythmic echo, and 1 s+ for ambient trails.
Pitch Change Effect
Choose whether repeats shift pitch with tempo, low-quality pitch shift, or high-quality pitch shift.
Pitch Change per Echo (semitones)
Set transposition between repeats. Negative values create descending dub-style tails; positive values create rising repeats.
Number of Echoes
Low values (2–4) stay clear and tight; higher values create dense, reverb-like cascades.
Allow Duration to Change
Enable this to keep the full tail. Disable it only if you intentionally want echoes cut at the current selection end.
Delay Time Reference Table
| Delay Time | Character | Typical Use |
|---|---|---|
| 0.05–0.12 s | Slapback | Vocals, guitars |
| 0.25–0.50 s | Rhythmic echo | Dub, electronic patterns |
| 1.0 s+ | Long ambient repeats | Sound design, transitions |
Delay vs Echo vs Reverb
- Delay: Flexible repeat engine with timing modes and per-echo pitch options.
- Echo: Simpler fixed-interval repeats with delay time + decay factor.
- Reverb: Dense reflections for room/hall ambience, not distinct repeats.
Common Use Cases
- Vocal throws and ad-libs
- Guitar slapback and rhythmic repeats
- Dub-style descending echoes
- Build-ups and transition effects
Tips for Best Results
- Keep repeat level decaying to avoid clipping and clutter.
- Sync delay time to track tempo for musical repeats.
- Use fewer echoes in dense arrangements.
- Enable duration change when long tails are important.
Frequently Asked Questions
Can I make echoes rise or fall in pitch?
Yes, use
pitch-change settings per echo.
Why is my delay tail cut off?
Selection length may be
too short or duration extension disabled.
Delay or Echo for beginners?
Echo is simpler; Delay
offers more creative control.
