Note: 
- Extreme pitch and tempo changes (for instance 24 semi-tones, which is quite a lot!) can lead to noise.
- Voice reduction quality depends on the input. It works best with little compressed music and assumes that voice was recorded in mono and later mixed into the stereo channels (which is the case for a lot of music recordings)

## Key features

- Change pitch and tempo independently
- Loop and select audio regions
- Import various audio formats
- Export to WAV and MP3
- Volume amplification
- Voice reduction

### 5/5 — Extrem nützlich für Chorstimmenübung

*2021-10-26*

Um Chorstimmen zu üben bastele ich mir mp3-Dateien in Musescore und nutze MSC um bestimmte Stellen zu wiederholen, das Stück tiefer zu setzen um die Stimmbänder zu schönen und mal langsamer zu üben. Die App hilft enorm.

### 2/5 — No timer

*2018-08-31*

The app doesn’t have a consistent time are following the actual time that your audio is playing at. When I stick a long file in this thing, and then I hit stop, I can’t just hit play and make it play from where it last stopped... it just starts from the marker. Also, I can’t start something over all the way from the very beginning. Unless I close out and re-load the audio as a new track, it will not start from the very beginning because I can’t get the red marker to slide all the way over to that side of the screen for some reason. Can you just have a “play from the beginning of the track“ button or something? Also, can you have a consistent time running so that I can see exactly where I’m at in the track and don’t have to guess? It is really annoying especially when I have longer tracks on here like a couple hours long or something…
