What this audio tool does

Audio Sample Rate Converter performs its work directly on decoded audio samples. It creates a new result instead of renaming or returning the original file.

The page runs a purpose-built audio sample rate converter routine on an AudioBuffer and encodes the output as 16-bit PCM WAV.

Long or high-resolution files need more memory because browsers hold decoded samples in RAM. Codec support depends on the browser.

Supported formats and limits

Input support follows the codecs built into your browser. Output is a broadly compatible PCM WAV file.

Stage	Format
Input	Browser-decodable audio
Output	16-bit PCM WAV
Processing	Local AudioBuffer samples

Example and practical tips

Start with a short representative clip, use moderate settings, and compare the original and result players. For audio sample rate converter, small changes are usually easier to judge than extreme ones.
