Music Speed Changer Lite is an Android application that allows you to change the tempo (speed) and pitch of an audio file in real time. Developed by M-Apps, this multimedia tool is perfect for practicing musical instruments, transcriptions, and language learning.

With this app, you can select an audio file, and change the tempo and pitch on the fly. You can also change the pitch and tempo (speed, time-stretch) independently, loop regions, and select regions. The app supports various formats, including mp3, wav, m4a, ogg, and aac.

The full version of Music Speed Changer, available on the Google Play Store, offers additional features such as HQ audio output, support for arbitrary pitch (even deviating from semi-tones), filtering, export to wav and mp3, volume amplification, channel selection, and an ad-free experience.
