Designed for musicians, Speedshifter Lite is a demo of Speedshifter, a practice tool that enables you to adjust the speed of any audio track without altering the pitch. It is perfect for musical, slow practice to a recorded accompaniment. Developed by ABRSM (the exam board of the Royal Schools of Music), it can be used with any compatible track in your music library* to help you learn new pieces.

This free lite version has all the functions of Speedshifter, but playback stops and has to be restarted after 60 seconds. It is useful for working on short passages of music, or to evaluate Speedshifter before downloading the full version.

Speedshifter Lite can also be used to:
- listen closely to tricky pieces you’re finding particularly hard to learn by slowing them down
- focus on specific sections using the loop function
- transpose a track up or down in semitones to fit with a preferred key or range
- set a reference tempo (BPM) by tapping in time with a track
- store tapped BPM and loop points automatically (once you’ve registered)
- sync BPM and loop settings seamlessly across devices once you’ve downloaded the free desktop version (
- sound a tuning note – simply shake for an A!

* Important info
- Speedshifter Lite supports playback of MP3, M4A, AIFF and WAV files stored directly on your device in the music library. It cannot play files downloaded or streamed via Apple Music, Spotify, Deezer, etc; or files stored online in iTunes Match.

- Speedshifter Lite allows repeated playback of any track from any starting point for up to 60 seconds. It is a free demo version of Speedshifter. The full version of Speedshifter does not feature this restriction on playback time.

SpeedShifter/Aural Trainer

These are good apps but having purchased full versions of both apps I have been unable to upgrade them. Numerous communications have had no response. It is disappointing to have to use a public forum to “hopefully” draw attention to this problem.

Poor app and customer experience

Bought this for my daughter’s violin practice and paid for the £4.99 upgrade. Even though the money was taken, I still get the Lite version.

Writing to the developers hasn’t helped. Almost a week after my email, there is no acknowledgment or solution to my problem.

Very disappointed with ABRSM for this sub-par app and customer experience!!

Better evaluation required

Having used this app on my PC I was looking forward to the release on iPhone / iPad. Having downloaded the lite version to evaluate the sound quality I am disappointed that the time allowed to listen to the track is so short. It's very hard to make a decision to purchase based on a 10 second trial. Poor judgement ABRSM.
