GUIDE / add reverb to audio online
What does reverb do?
An online reverb effect surrounds dry audio with many delayed reflections that suggest an acoustic space. SoundTools generates a stereo impulse response, renders it through an OfflineAudioContext with adjustable wet mix, decay, and pre-delay, and creates a WAV inside your browser without uploading the source recording.

FIELD NOTES / 01
A real local processor, not a decorative upload box
OfflineAudioContext + generated convolution impulse runs after you choose a source and explicitly start the operation. The audio samples remain in browser memory; SoundTools does not send the selected media to an application endpoint.
Choose Room, Hall, Plate, or Cathedral, then adjust wet mix, decay time, and pre-delay before rendering the complete local file. Results remain available for preview and download only in the current tab. Closing or refreshing the page releases those temporary objects.
PROCESS / THREE STEPS
How to use reverb
- 01
Choose the local source
Open a compatible file in the dedicated workbench at the top of this page. The browser validates and decodes it without an upload step.
- 02
Set the useful controls
Choose Room, Hall, Plate, or Cathedral, then adjust wet mix, decay time, and pre-delay before rendering the complete local file.
- 03
Process, check, and export
Run the local processor, inspect the status and preview, then save Reverberated WAV when the result is ready.

What this tool actually does
Clear limits are part of a useful tool. These values describe the processor currently running in this page.
Runtime and model assets may be downloaded, but the selected file is not attached to those requests.
The dedicated workbench exposes only formats it can actually produce in the current browser.
USE CASES / 02
Useful reasons to open reverb
- Vocal space
Add a controlled room or hall tail to a dry authorized vocal.
- Piano and instrument depth
Move an isolated instrument away from the front of the mix.
- Sound-design atmosphere
Create exaggerated plate or cathedral tails for transitions and effects.
QUESTIONS / PRACTICAL ANSWERS
Questions about this tool
Answers based on the current browser processor—not promises about a future version.
01Is my audio uploaded for processing?
No. Audio samples stay in browser memory. The page may download a codec or model asset, but it does not send the selected file with that request.
02Why can the first run take longer?
This tool uses OfflineAudioContext + generated convolution impulse. A browser may need to download and initialize that runtime before the first operation; later runs can reuse cached assets.
03Can I preview the result before saving?
Yes. Audio-producing tools expose local result players, while analysis and transcription tools show their detected data before download.
04What happens when the browser is unsupported?
The workbench reports the missing capability instead of uploading the media or pretending that processing is still running.
05Can I add a hall effect to a voice?
Yes. Start with the Hall preset, then adjust wet mix and decay while comparing the rendered WAV with the dry source.
06Does reverb processing happen in real time?
No. SoundTools renders the complete file with OfflineAudioContext, then provides a separate preview and WAV download.
