MP3 to WAV
Convert an MP3 file to WAV (PCM).
Upload an MP3 and download a WAV with 16-bit PCM. Sample rate and channels follow the source when possible. Expanding to WAV does not recover detail already lost in MP3 compression. One file up to 10 MB; temporary storage only.

FAQ
MP3 to WAV expands the stream to PCM; it does not restore detail lost during original MP3 compression.
Yes. Files are transferred over a secure connection, encrypted while stored on the server, and automatically deleted. Flimpa does not store documents permanently and does not use them to train models.
