About 444 Hz Tuner
444 Hz Tuner is a free browser pitch changer for audio files. Drop in an MP3, WAV, AAC, M4A or FLAC, and it detects the song's A4 tuning and retunes it to 444 Hz or 432 Hz without changing the tempo. Nothing is uploaded to a server — the processing happens on your own machine — and you download the retuned file when it's done.
