5. Adjusting playback-speed with a customized app on your phone or tablet:
Music Speed Changer
Music Speed Changer is an audio speed changer and pitch shifter tool for audio files on your device, where the tempo change is in real time without affecting the pitch (time stretch), and the pitch change occurs without changing the audio speed (pitch shift). This type of audio speed changing has many uses including practising instruments.
The app’s superior sound quality and usability make Music Speed Changer the favourite musician’s music player of its kind.
This app really has superior sound quality, even when the music is slowed down or speeded up, you will not notice this in the sound quality. The loop function is useful when practicing a difficult passage. And the Pitch change is useful when transposing (when a piece starts on a different note). Works on iOS and Android. Highly recommended !
Tip: Connect your phone or tablet to a powerful Bluetooth speaker to hear everything clearly while playing together or use a headset!
