Audio Speed Changer Pro allows you to modify the playback speed or pitch of your audio files "on the fly" (realtime), fitting their audible characteristics to your needs. It can be used to help transcribing audio, to transpose songs, to save time listening to audiobooks/podcasts, to practice dance steps or just to have fun!

How it works: Choose a file, all songs from a folder or a whole album from your personal collection, limit the time frame you want to listen to, set the percentage of speed change you want to apply, set the number of semitones you want to transpose and just press play!

List of features:

- Audio formats supported: mp3, ogg, wav, vox, gsm, aac, m4a, mp4, aif, wma, flac, ac3, mp2, tta.
- Load songs, folders or whole albums (press and hold for options)
- Search songs using the music library or exploring folders and files
- Speed up or slow down audio up to 400% (0.25x - 4x in speed)
- Change pitch from -1 to +1 octave (in semitones or 0.05 semitone steps)
- Export audio as new MP3 or WAV files
- Start and End markers: limit the timeframe you want to listen to by drag&drop or precise setting.
- Song Position marker: set the position you want to start listening to at any time!
- A-B loop and repeat mode
- Plays in background
- Auto saves configuration for each song
- Auto saves song's position for a future session

    I have downloaded this app but can't seem to playback the file. Is there a trick to it? . I've rated it average just because I don't want to give a bad rating but I can't properly rate because I can't use it.
