When you select track, the app is going to prepare sound data for enabling reverse playing (It usually takes few seconds for normal-length track on new & fast devices). It does NOT change your original files.
Tracks that can fit into memory do not require free storage to work. However bigger tracks may require temporary space for uncompressed tracks on your device. Usually you don't have to worry about this.
If you want to have more fun you can change tempo or pitch of your music track.
"Tempo" describes how fast sound will be played, 100% is original/non-changed tempo, 50% is 2x slower, 200% is 2x faster. Range is: 25% - 400% .
"Pitch" describes how pitch will be changed with difference represented as -24.0 .. +24.0 semitones, 0.00 is original/non-changed pitch.
These values may be adjusted by slider or by clicking button near them and setting accurate value.
You may also save your reverse music into file.
Supported formats for export / saving: wav/acc/mp4 (various BPS).
Please note that most of operations are cpu-intensive and for good results you need a performant device. Usage of multiple features at once (like tempo change + reverse play) increase hardware requirements.
