Change your music's tempo and pitch in realtime quick and easy. Just select an audio file, mark the region you want to play (and loop/repeat) and change speed and pitch on the fly. It is also possible to export the changed audio file. Use cases of Audio Speed Changer are for instance: practicing guitar and other music instruments, transcriptions, change the speed of audiobooks... This version is optimized for the iPad. iPad 2 or newer are highly recommended due to low resources of the iPad 1st generation. Features: - Change pitch and tempo (speed, time-stretch) independently - Loop region - Select region - Filtering* - Import various formats including mp3, wav, m4a, ogg, aac, ... - Export to wav and mp3* - Volume amplification* - Voice reduction* - Separate playing of left/right channels * - Import from Dropbox *NEW* - Send files by email* *NEW* * Advanced version's features APS Player: 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)

    As a practicing guitarist this is valuable in slowing down tricky guitar parts enabling me to work out intricate passages . It does what it says and it works excellently
  • Restore/purchase doesn't work

    By DGRomanis
    I bought the advanced/pro version for £2.99 but it doesn't seem to want to remove ads or enable saving. What a con! I'll be reporting this to Apple as I've been done out of money for nothing!!

    Add a save button and problem solved
  • Other reviews are not accurate!

    By CD buyer advice
    The other reviews are wrong in saying that there is no save button, because there is no need for one. It saves automatically!
  • It's a decent app nevertheless..

  • Plagued with Adverts

    By I also don't have a nickname
    It was impossible to find out amid all the Adverts, how one actually uses this App for the purpose it was installed. There was no help. It was illogical.
  • Great app but a little dodgy

    By Icopternerd
    This app is awesome. It's great fun listening to your songs with a higher pitch and increased tempo. However, when I increase the pitch, I can hear some kind of faint static sort of sound when I'm playing the song. Sometimes the song stops playing altogether and I just hear loads of static. If you could fix these problems that would be great. Thanks.
