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%.

Features:
-Pitch shifting- change song pitch up or down 24 semi-tones, with fractional semi-tones allowed.
-Time stretching - change audio speed from 15% to 500% of original speed (change BPM of music).
-Utilizes professional quality time stretching and pitch shift engine.
-Rate adjustment - change the pitch and tempo of the audio together.
-Opens most audio file formats.
-Music looper - seamlessly loop audio sections and practice over and over (AB repeat play).
-Advanced looping feature - move the loop to the next or previous measure or set of measures with the touch of a button after the perfect loop is captured.
-Reverse music (play backwards). Decode the secret message or learn a passage backwards and forwards.
-Playing queue - add folder or album to the playing queue and add/remove individual tracks.
-Waveform view showing contours of the audio for precise seeking.
-Equalizer - 8-band graphic equalizer, and preamp and balance control.
-Analyze the audio to display the BPM and musical key of each track.
-Markers - bookmark positions in your audio.
-Audio effects - apply effects such as echo, flanger and reverb, or reduce the vocal levels in the music for a karaoke effect.
-Great for making Nightcore or Fast Music creations.

Why did you move the tempo to the top and pitch to the bottom?! I'm more used to the tempo being at the bottom and pitch at the top! And if I set the second loop point, it takes me to the beginning, causing me to get the message, "Can't set loop point here." And the ads are A LOT worse that the older versions in 2023. Those versions were significantly better.

I originally gave this app a 5 star rating but in the last 6 months it's been crashing on my S22 phone. Otherwise it's the perfect tool for learning tunes by ear and for transposing into different keys. Sound quality is amazingly good! I hope they improve the stability so I don’t have to find another app. The response from support about battery saver is incorrect. The following message appears: Something went wrong with Music Speed Changer Music Speed Changer closed because this app has a bug.

The music stopping when the app is in the background is the device battery optimizer. To fix, go to your device settings and tell the battery optimizer not to stop the app. More info: https://dontkillmyapp.com If you are experiencing a different issues, please contact support@musicspeedchanger.com with more information for help.

This app has a lot of features that I soon realized that I could admire amongst other apps. However as a recently it closes and crashes every 5 seconds once I've started to play a song, so I can't even use it anymore. Unfortunately if it's not fixed then I'll be finding a different app to enjoy my music

Restart the device. The music stopping when the app is in the background is the device battery optimizer. To fix, go to your device settings and tell the battery optimizer not to stop the app. There is also a link in the app settings to take you to the device battery optimizer.
