What this tool does
Keep a short portion of a WAV recording without re-encoding its sample values. Enter a start and end time in seconds. Boundaries are aligned to complete sample frames, so stereo channels remain synchronized. The output keeps the original sample rate, channel count and integer bit depth while writing a clean WAV container around the selected samples.
Supported formats and limits
Input must be classic RIFF/WAVE integer PCM with one or two channels and 8, 16, 24 or 32 bits per sample. Compressed WAV, RF64, extensible format and IEEE float are unsupported in this tool. An empty end field selects the file’s end. The interval must fit inside the recording and contain at least one frame. Input and output are capped at 4 MiB; original non-audio metadata chunks are omitted.
What should I check before using the result?
Input must be classic RIFF/WAVE integer PCM with one or two channels and 8, 16, 24 or 32 bits per sample.
Is input uploaded?
This tool sends input to this site’s conversion API after you select Convert on server. Files use bounded workers and, when needed, private temporary folders deleted after processing or cancellation. No conversion history is saved. The converter does not upload files to a third-party conversion service.
