## What is PSLM Sound?

Loud, clean, release-ready masters — made right here on your device.

PSLM turns a rough mix into a finished master without uploading a thing. No account, no cloud, no waiting in a queue. It works with the network switched off.

YOUR MUSIC NEVER LEAVES YOUR DEVICE
Analysis, mastering and export all happen on your iPhone. There is no server, nothing listening in, and no sign-up between you and your song. Cloud mastering services need your file on their machines to work at all. PSLM doesn't.

PSLM LISTEN — THE BRAIN
It listens to your track and tells you what to fix — boom, harshness, mud, phase — in plain English, with a number. Then it sets the chain for you. Take the suggestion or overrule it.

LOUD, BUT CLEAN
A clip-before-limit engine, band-split and sub-protected, gets your record as loud as modern streaming asks for without the harsh, crunchy artifacts that usually come with it. Four loudness tiers: Low, Mid, High, or Smart, which picks for you based on the track. Everything stays true-peak safe and is never hard-clipped.

CHECKED BEFORE YOU GET IT
After every render PSLM verifies true peak, loudness, clipping, phase, dynamics, and whether the master introduced any mud or harshness that wasn't in your source — and quietly corrects the safe problems before the file lands.

SMART BASS LIMITER
Tames just the 808 that's clipping, so the low end stays huge without pumping the whole mix.

SONIC PROFILE
Point it at a reference you trust. PSLM builds a tonal and width profile from it and matches your master to that feel.

ALBUM MASTERING
Batch a whole project with coherent loudness across every track, so the record holds together instead of jumping between songs.

EXPORT
WAV 24-bit for lossless delivery, WAV 16-bit for CD, FLAC, and AAC.

BUILT FOR 808-HEAVY, VOCAL-FORWARD MUSIC
The voicing is tuned around trapsoul, trap and drill because that's what it was built for — but it works on any music, and Sonic Profile lets you aim it at a reference from any genre.

PSLM is made by Callo. No ads, no analytics, no tracking.
