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 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%.

👍 Highly recommend this app if you like to experiment & alter the sound of the music you listen to. A lot of great features & settings like preamp, limiter & compressor. Great sounding reverb, echo & flanger effects. I really love the ability to change the music speed & pitch separately or synced. You can also make a new mp3 copy with all the settings & effects that you applied to a song. I wish it had a Crossfade feature to make the ends & beginnings of songs overlap & blend into each other.

This app is truly amazing. I'm so happy I found it. Not only does it serve as a wonderful normal music player, it adds SO many useful features for modifying or changing audio, to adding effects, changing speeds, amplifying, to changing metadata and being able to export your changes, all for free! there are a couple of ads once in a while, but they are so short and I absolutely don't mind due to how great this app is.

I am astounded by how awesome this app is! I wished we had this type of technology back in the day. Especially from such splendid apps as yours. The greatest feature is the capability to adjust pitch and/or tempo both fowards & reverse. Much easier than reversing with open reel to reel. Really inspired work I find here! 5 stars is simply not high enough value. It should be billions of stars. 🎸🎸🎸🎸🎸
