Repair & master songs, louder
About

It then masters tracks to streaming loudness, offering detailed control and genre-specific profiles. Users can also match their audio to reference tracks and export high-quality files.

The results screen now lists the whole chain. Every EQ filter and every compression band is there with its numbers, along with the de-esser, the stereo moves and the limiter. The repair lines carry their numbers too. The 9 kHz shelf is listed now, and the widening shows its +2.5 dB. Before and After now play at the same loudness in both directions. If your track came in louder than the master, Before used to play louder. It no longer does. An album no longer gets stuck on one bad file. Take the track out, master the rest, and export what finished. When the record is done you can change the genre and master it again. Restore Purchase tells you what it found. A purchase that fails says why. One that is waiting for Ask to Buy says so, and the app unlocks by itself once it is approved. When a master, an export or a video fails, the app tells you what happened instead of going quiet. Settings scrolls on small screens, and the unlock sheet fits large text. Product page links for hip-hop, deep house, drum and bass and funk open on the right genre. First master is free. Pay once. No subscription. Nothing leaves your device.
