Audio Reverse Effect Maker
Reverses the sample order separately in every decoded channel. The final sample becomes the first, while duration and channel order are retained in the 48 kHz PCM16 WAV.

Limits and verification
Reversing twice restores the decoded order, but source decoding, resampling and 16-bit quantization can prevent byte-identical round trips. Container metadata is not retained; this is not phase inversion.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
How does Audio Reverse Effect Maker process the signal or file?+
Reverses the sample order separately in every decoded channel. The final sample becomes the first, while duration and channel order are retained in the 48 kHz PCM16 WAV.
How can I reproduce the Audio Reverse Effect Maker example?+
Example file: /examples/audio-stereo.wav; Download the example file and select it in the file input. Click “Process locally”. Download the result and inspect: czoa-audio-reverser.wav — PCM16; 48000 Hz; 2 channels; 72000 frames
What limits apply to Audio Reverse Effect Maker?+
Reversing twice restores decoded sample order, but decoding, resampling and 16-bit quantization can prevent byte-identical results. Truncated declared RIFF/WAVE data is rejected before reversal; container metadata is not retained and sample reversal is not phase inversion.
What does browser-isolation evidence establish for audio reversal?+
Network requests observed during the example contained no selected-audio payload while the fixture reversed decoded WAV channels and independently compared samples. This establishes the tested browser value path only; decoding, page resources, extensions and other networks remain outside scope.
