Reverb & Impulse Response Studio
Convolve audio with a real impulse response. Shape the room, audition every change, and export a finished WAV — without uploading your recordings.

Shape the reverb
Levels and tone changes apply to the live preview.

Smooth the end of the impulse to reduce clicks
04 / LISTEN
Audition the result
Listen to the live convolution before exporting.
Live listening follows your current settings. Preview uses your browser's audio device. Export is rendered separately.
05 / RENDER
Make it yours
Export a processed WAV with cancellable encoding.
Rendering offline…
WAV is uncompressed. Changing any setting requires a fresh render. WAV encoding can be discarded between chunks. A render can use substantial memory; oversized jobs are blocked before processing.
HOW IT WORKS
From room impulse to finished sound.
Pick your space
Import an impulse response or start with a locally generated small room, hall or plate profile.
Listen, refine, export
Adjust reverb levels, pre-delay and tone, then render and download a WAV with optional full tail.
Questions before you start?
Does PixelOkay upload my audio or impulse response?
No. This standalone tool uses the Web Audio API entirely in your browser and makes no external processing requests. Your audio remains on your device unless you choose to save the result.
Can I use WAV, MP3, FLAC, or AAC?
The studio accepts files your browser can decode with the Web Audio API. Format and codec support vary across browsers and operating systems. Export is always WAV.
Does export include the entire decay?
When “Include complete reverb tail” is enabled, the studio renders the original audio duration plus the impulse response duration and pre-delay. Turn it off to render only the original duration.
Why is the rendered audio louder or quieter?
Wet/dry levels, IR normalization, and output gain affect amplitude. Use peak normalization for a file peaking at −1 dBFS. Integer PCM clips peaks exceeding full scale; 32-bit float preserves headroom above 0 dBFS.
Does this support true stereo impulse responses?
Mono, stereo and four-channel true-stereo impulse responses are supported by Web Audio's convolution node. Your browser may not decode every four-channel file format.
