Welcome to Speedshifter
Speedshifter is a practice tool from ABRSM that allows you to vary the speed of audio without altering the pitch!
Simply load a track and turn the dial to slow it down or speed it up - the pitch remains the same. If you load an ABRSM minus one track Speedshifter will know the starting tempo of the track and position the dial automatically at the correct point on the tempo/BPM ring.
What is ABRSM’s Speedshifter?
Speedshifter is available as a free desktop application for Windows and Mac computers, or as an app for iOS and Android phone and tablet devices. Users of compatible mobile devices can download Speedshifter as a free, Lite installation for trial purposes (with a one minute playback restriction), or as the full paid version with comparable functionality to the desktop version.
Speedshifter can be used to slow down the playback speed of most common compatible audio file types. Follow the relevant download link to install the relevant desktop application or to read more information about the iOS and Android apps.
How might I use Speedshifter?
Speedshifter is designed to be used whenever a student might benefit from playing along with the accompaniment at a reduced tempo. It can be used in a lesson, or it can be used by the student in their own practice sessions.
Because Speedshifter varies the speed of the audio recording, any fluctuation of tempo is kept. This ensures that Speedshifter provides, in many cases, a more musical solution to slow practice than a metronome.
Speedshifter contains four further features that are useful tools in practice sessions and lessons:
Speedshifter now incorporates a loop feature that allows users to repeat a section of a track for practice purposes. Simply slide the left and right markers to the desired start and end points and Speedshifter will repeat through the selected section.
Speedshifter works with any CD or MP3, not just ABRSM recordings. However, when using non-ABRSM material, Speedshifter will ask you to tap along to the track for a few bars so it can work out the tempo. This will enable Speedshifter to position the track on the tempo ring. This function is also useful when you need to quickly establish the tempo of a piece of music.
Although Speedshifter varies the speed without changing the pitch, pitch adjustment is also possible. Pitch can be shifted in semitone steps to a range of a minor third up or down. This is particularly useful to singers, especially in conjunction with one of ABRSM's Songbook CDs.
Before you start using Speedshifter you can tune your instrument to an A (440hz) played on an instrument of your choice, a synthesized tone, clarinet, trumpet, cello or even the piano used in ABRSM's recordings.
