432 Player: the 432Hz music player for Android and iPhone

432 Player is a music player app for Android and iPhone that retunes the songs on your phone to 432Hz as they play, without touching the original files. On Android it shifts only the pitch, so the tempo stays exact. First released in April 2013; free on Android with optional Pro, a one-time purchase on iPhone.

Free vs ProWhat is free in 432 Player and what Pro adds

What makes it different

  1. Called the first smartphone app made for 432Hz music

    432 Player came out on iPhone on 15 April 2013 and on Android on 30 November 2014. A peer-reviewed article in the Journal of Popular Music Studies (2021) calls it the first smartphone app developed for 432Hz music.

  2. Pitch moves, tempo stays

    On Android, a dedicated time-stretch engine lowers only the pitch, so a four-minute song still lasts four minutes. Speed-based retuning, which some tools use (and our extension offers as a light option), slows the track by about 1.8%.

  3. Your files stay exactly as they are

    Retuning happens live during playback, in 32-bit floating point. Nothing is converted or written back to your library, so switching between 432Hz and 440Hz is instant.

  4. Plays lossless and hi-res files

    FLAC, ALAC, WAV, AIFF, APE, Opus, M4A, MP3, WavPack, DSD and more play natively on Android. Output runs at 44.1 kHz, with a 48 kHz option in settings.

  5. 432Hz beyond the phone speaker

    Cast to Chromecast or DLNA speakers and TVs and they receive the retuned sound, not the original. Android Auto is supported in the car.

How it works

  1. Step 1

    Install 432 Player

    Free on Google Play, or a one-time purchase on the App Store.

    Open your music

    Browse the songs on your phone by folder, album, artist, genre or playlist.

  3. Step 3

Features

  • 432Hz free, more tunings with Pro

    432Hz is free on Android. Pro adds 528Hz (applied as A=444), Solfeggio 396 to 963Hz and any custom frequency, and lets you preview them first.

  • Per-song source tuning

    Tell the app a track was recorded at 444Hz or another reference, and the shift to 432Hz is calculated from there (Pro).

  • 10-band equalizer

    Ten bands from 32Hz to 16kHz with presets (Pro), plus free bass boost and reverb.

  • Synced lyrics

    Lyrics scroll with the song when timed lyrics exist. Free.

    Browse and play your 432Hz library from the car screen.

  • Cast in 432Hz

    Send retuned audio to Chromecast and DLNA devices, including many smart TVs.

    Skins, themes, colours from the album art, a visualizer, widgets, lock-screen controls and a sleep timer.

  • Radio inside the app

    A radio tab with 30,000+ stations, retuned live. Every station and station search are free; free keeps 3 favorite stations and Pro has no limit.

  • Eight languages

    English, Russian, Hebrew, Spanish, Persian, Bulgarian, Polish and Italian, with a per-app language picker on Android 13 and newer.

Who it is for

  • You keep your own music files and want to hear them in 432Hz without converting anything.
  • You care about tempo: you want 432Hz without the song slowing down.
  • You listen in the car or on a speaker and want 432Hz there too, through Android Auto or casting.
