How the audio to wav converter works

The source is decoded to raw samples with the browser's built-in codecs and written out as a 16-bit PCM WAV at the original sample rate. WAV is the lowest-common-denominator format: uncompressed, patent-free, readable by every DAW, editor, court-transcription workflow and embedded system since the 1990s. Decoding a lossy source doesn't restore lost quality — it makes the already-decoded audio maximally compatible.

Know what conversion can and can't do: MP3 → WAV does not "upgrade" the audio — the MP3's losses are permanent; the WAV just stores them losslessly (in a much bigger file). The conversion is for compatibility: tools that demand WAV input, editing without generation loss, or archiving a decode. Expect ~10 MB per stereo minute.

Frequently asked questions

Does converting MP3 to WAV improve quality?

No — lossy compression discards audio permanently; conversion just re-packages what's left. The value is compatibility and editability: WAV re-saves without further generation loss, unlike re-encoding MP3 to MP3.

Why is the WAV so much bigger?

WAV is uncompressed PCM: 44.1 kHz stereo 16-bit is about 10 MB per minute, always. A 4 MB MP3 of a 4-minute song becomes roughly 40 MB of WAV.

What sample rate and bit depth does the output use?

Your file's original sample rate (commonly 44.1 or 48 kHz) at 16-bit — the CD-standard combination that every application accepts.

What input formats can I convert?

Anything the browser decodes: MP3, M4A/AAC, OGG, FLAC and WAV itself. If it plays in a browser tab, it converts here.

Is the audio sent to a server for conversion?

No — the browser's own decoder does the work locally. It runs offline, and no copy of your file exists anywhere but your device.
