Published by PitchChanger · How these guides are made
Hear the difference
Listen to the gaps after each note and the ending. The source is identical in every version; only the listed effect changes. Start at a comfortable listening volume.
Pause your workspace preview before comparing these clips.

How to use this workflow
Load and preview the source
Choose a supported mono or stereo file and listen to a passage with gaps. Those gaps make it easier to hear the decay and repeats.
Choose a room and adjust the mix
Start with Small Room, Medium Room, Large Hall, Cathedral, Plate or Spring. Adjust the reverb controls and, if needed, enable delay and set its time, feedback and mix.
Render the complete tail
Generate the effect after your final changes. Compare source and result, including the ending, then download WAV or MP3. A new setting requires a new generated result.
Choose settings for clarity
Wet mix determines how much effect is blended with the dry signal. A longer decay leaves more sound after each note. Pre-delay creates a short gap before the reverb begins, which can help separate the initial attack from the reflections.
Delay time controls the interval between repeats; feedback controls how much repeats again. For a quarter-note starting point, divide 60 by BPM to get seconds: at 120 BPM, one beat is 0.5 seconds. Enter settings manually; this example is arithmetic, not automatic tempo synchronization.
Why the output may be longer or quieter
The renderer includes additional time for reverb and delay tails. Long decay or high feedback settings increase output duration and memory use. If a render exceeds the browser’s memory budget, shorten the source or reduce the effect.
When summed samples would overload, the renderer can reduce the output gain. This protects the generated samples but can make the whole result quieter. The room presets use synthesized impulse responses; their names are sound-design descriptions, not recordings of specific physical venues or hardware.
Starting settings for voice, guitar and spacious effects
Choose a preset first, then make the listed adjustments. These are listening starting points, not automatic enhancement settings. A dry spoken phrase and a dense song will need different amounts of effect.
Swipe or scroll sideways to read all columns.
| Goal | Try these settings | Listen for |
|---|---|---|
| Keep a voice close | Small Room; reverb mix 0.15; delay off | Words stay clear; a short tail fills the gaps |
| Give a guitar phrase an echo | Reverb off; delay 0.50 s; feedback 25%; delay mix 25% | Distinct repeats one beat apart at 120 BPM |
| Create a longer sense of space | Large Hall; reverb mix 0.25; delay off | Notes trail into the gaps without covering the next attack |
When the result sounds muddy or the tail seems missing
Lower Reverb mix first, then shorten Decay if notes still overlap. Listen with Feedback delay disabled to separate the two effects. If the source already contains room sound, adding more reverb can make it harder to understand.
Use Generate effect and compare Rendered result through the ending before downloading. The export preserves the effect tail; trimming it afterward or stopping playback at the original duration can hide that tail.
Common questions
Can reverb repair a noisy recording?
No. It can also spread the noise into the tail. Begin with a cleaner source when possible and compare at a similar listening level.
Can I add reverb without slowing the recording?
Yes. This page adds reverb and delay without a speed control. Use Slowed + Reverb when you want a linked pitch and speed change as well.
Can I export MP3 and use this on my phone?
After Generate effect completes, download WAV or use Export MP3 320k and then Download MP3. Processing runs in the browser; mobile codec support and memory vary. Try a short clip first if a long recording fails.
