Synthetic Convolution Reverb WAV Processor

About this synthetic convolution reverb wav processor

Apply synthetic convolution reverb or a six-reflection room model locally with wet/dry control, then export 48 kHz PCM16 WAV. Input must be smaller than 50 MB Processes streaming audio and video buffers directly in the browser using HTML5 Media and Web Audio APIs with zero server uploads.

Audio and video decoding pipeline

The execution engine processes input tokens and applies transformations in the browser sandbox. Specifically, Decode locally at 48 kHz and mix (1 − wet) × original + wet × convolved audio. The default remains a random synthetic impulse with squared decay, native convolution normalization, 3 seconds and wet only. Room mode instead uses deterministic early reflections with normalization off. Output length is input plus impulse length minus one frame. No audio is uploaded. Room mode uses six first-order wall-image reflections. Dimensions are L×W×H; the source is at (L/4, W/2, 1.2) m and receiver at (3L/4, W/2, 1.2) m. Sound speed is 343 m/s; each reflection has gain 0.6/distance and delay rounded to the nearest sample. Coincident taps add. Both channels use the same impulse without mixing channels. The wet path contains no direct sound; convolution normalization is off.

Buffer duration & codec support limits

Operational constraints and validation boundaries: Input must be nonempty and smaller than 50 MB (50,000,000 bytes), checked before reading or decoding. Impulse buffer duration is 0.2–5 seconds; wet mix is 0–1. Output is 48 kHz PCM16 WAV with the full buffer tail, even for dry-only mix. Only the synthetic mode changes its random impulse between renders. Mixing does not guarantee constant loudness or prevent clipping. Metadata is not preserved. Only six early reflections are modeled: no higher-order reflections, diffuse tail, material or frequency-dependent absorption, or HRTF. The 0.2–5-second control sets the impulse buffer length; samples after the last reflection are silent. This is not a measured or physically validated room-acoustics simulation.

Audio and video rendering in Synthetic Convolution Reverb WAV Processor depends on browser hardware and supported media codecs. Verify playback compatibility on your target platforms.

In-memory audio-video processing boundary

File buffers and document assets in Synthetic Convolution Reverb WAV Processor are processed in-memory via local browser APIs with zero file uploads to CZOA servers.

HTML5 Media & Web Audio standards

W3C Web Audio API specifications and HTML5 media container standards:

• Web Audio API ConvolverNode: generated random squared-decay impulse; native normalization retained
• Linear dry/wet mix: (1-wet) original + wet convolution; 0–1 wet range
• OfflineAudioContext:48 kHz PCM16 WAV with N+M-1 frames; not a physically validated room model
