Return to Faith Ministries
Music Apps
Three free apps built for our own studio work — tuning, vertical edits and file compression. Every song and video on this site passes through them.
The workflow
Made to solve our own problems first
Each of these started as an obstacle in the middle of a release. Songs needed to be retuned to 444 Hz and verified. Music videos needed vertical cuts that didn’t crop the singer out of frame. Files needed to be small enough to load quickly without sounding thin.
All three run entirely in your browser — nothing is uploaded, nothing is stored, and none of them cost anything. If they save you the evening they saved us, take them.
444 Hz Tuner
444hz.app
Detect a song’s tuning and retune it to 444 Hz or 432 Hz — no tempo change.
A free browser pitch changer for MP3, WAV, AAC, M4A and FLAC. Drop a song in, and it measures where the recording’s A4 actually sits, then retunes the whole file to the reference you choose — 444 Hz, 432 Hz, or anything between 400 and 480 — without touching the tempo.
It is the tool every Return to Faith release is checked against. The 528 Hz checker on the same site reports where a track’s C5 truly lands, in hertz and in cents, so a file labelled 528 can be verified instead of trusted.
- Retune to 444 Hz or 432 Hz with no tempo change
- Reads MP3, WAV, AAC, M4A and FLAC
- Measures a song’s existing A4 before changing anything
- Runs in the browser — nothing is uploaded
My Shorts Studio
myshortsstudio.com
Turn a 16:9 music video into ready-to-post 9:16 Shorts.
Upload a widescreen music video and it returns three to five vertical clips, cut on the beat and reframed scene by scene so the subject stays in the frame instead of being centre-cropped off the edge of it.
Every clip can be trimmed, re-cropped, split or merged before export, and the whole thing runs in the browser — the video never leaves the machine it was made on.
- Beat-aware clipping into 3-5 Shorts
- Scene-by-scene reframing to 9:16
- Trim, split, merge and re-crop before export
- Runs entirely in your browser
Compress My Media
compressmymedia.com
Shrink audio, video and images locally in your browser.
Compress audio (MP3, WAV, M4A, AAC, FLAC), video (MP4, MOV, MKV, WEBM, AVI) and images without uploading anything. Pick a compression level, queue up a batch, preview the result, and download.
It is what every song and music video on this site is run through before it is posted — smaller files, faster pages, and no visible drop in what you hear or see.
- Audio, video and images in one place
- Batch queues with per-file compression levels
- Preview before you download
- Nothing is uploaded — it all happens locally

These three are only part of the workshop. The full collection of free browser tools lives on our apps site, and new ones join it as we build them.
