Audio Reverser
Reverse audio samples with optional linear fade-in and fade-out, then download 48 kHz PCM16 WAV; input must be smaller than 50 MB.
About this audio reverser
Reverse audio samples with optional linear fade-in and fade-out, then download 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, Each decoded channel is reversed independently, preserving channel order and duration. Optional linear fades reduce the start and end of the reversed signal. Fade lengths are rounded to sample frames; a one-frame fade sets that edge sample to zero. With both fades at zero, reversing twice restores the decoded sample order. Processing stays on this device.

Illustrative output:
Buffer duration & codec support limits
Operational constraints and validation boundaries: Input must be nonempty and smaller than 50 MB (50,000,000 bytes). Each fade must be a finite number of seconds from zero to the decoded audio duration. Fades apply after reversal; overlapping fades multiply. Output is 48 kHz PCM16 WAV. Decoding, resampling and quantization can prevent byte-identical round trips, and metadata is not preserved. Fades reduce abrupt edges but do not guarantee removal of all clicks.
Audio and video rendering in Audio Reverser 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 Audio Reverser 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:
- W3C Web Audio: channel-wise decoded PCM sample reversal
- Linear sample-index fade envelopes applied after reversal; overlapping gains multiply
- RIFF/WAVE PCM16 output at 48 kHz; metadata not retained
