About this app

Music Speed Changer allows you to change the speed of audio files on your device in real time without affecting the pitch (time stretch), or change the pitch without changing the speed (pitch shift). Alternatively, both speed and pitch may be adjusted together with a single control. The app is a music looper as well - you can slow down song speed and loop sections of the music for easy practice.

You can also save the adjusted audio to an MP3, FLAC, or WAV audio file for sharing with friends or listening in another player.

Music Speed Changer is great for musicians practicing an instrument needing to slow down the tempo or practice in a different tuning, speeding up audio books for faster listening, making nightcore or just rocking out to your favorite song at 130%.

Features:

-Pitch shifting - change song pitch up or down 24 semi-tones, with fractional semi-tones allowed. Range of modification may be adjusted in the app's Settings.
-Time stretching - change audio speed from 15% to 500% of original speed (change BPM of music). Range of modification may be adjusted in the app's Settings.
-Utilizes professional quality time stretching and pitch shift engine.
-Formant correction for more natural sounding vocals while pitch shifting (Pro feature, requires in-app purchase or subscription).
-Rate adjustment - change the pitch and tempo of the audio together.

It does what it says it does and a little more, quite cleanly delivering a very user-friendly and satisfying experience. It's a very useful tool as a musician who listens to very technical music and needs to hear it slowed down. I can make slow recordings and speed them up. I can change the pitch so I don't have to retune my guitar and it shows the key before and after, you get the idea. The ads are very unintrusive in my opinion.

Been using this app for years, simple, clean, and ads are minimally intrusive with only a small recurring charge or a $10 lifetime charge, with an option to remove ads for an hour. Plenty of available features in the base version as well. Rip google music.
