Features:
★ Play modified music / sound in audio formats: wav/mp3/ogg/flac.
★ Change Tempo of track in range 4x slower to 4x faster.
★ Set Pitch Octaves Change between -1 and +1.
★ Save / Export modified track to: wav/ogg/flac.

★ 2 modes of changing Tempo & Pitch - slider (fast) / pad (accurate).

Usage:
To play modified track just click "SELECT" button and choose track from music library or by browsing your device.

Supported formats: wav/mp3/ogg/flac.

If you select .wav file, then music may be instantly played. For other audio formats sound must be prepared for optimized playing (It usually takes few seconds for normal-length track on new & fast devices). It does NOT change your original files.

App requires temporary space for uncompressed tracks on your device. For normal 3 minutes long track is about 20MB, for longer more, for shorter less. 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.
"Relative Tempo" describes how fast sound will be played, 1.00 is original/non-changed tempo, 0.5 is 2x slower, 2.0 is 2x faster. Range is: 0.25 .. 4.0 .
"Pitch Octaves Change" describes how pitch will be changed with diffrence represented as -1.00 .. +1.00 octaves, 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 music into file.
Supported formats for export / saving: wav/ogg/flac.
For OGG format encoding may be long task.

Please note that most of operations are cpu-intensive and for good results you need a performat device.

Notes:
Tempo & Pitch values are auto-saved. When you select new track these values are set to default values.
