The Pro version has formant correction for pitch shifts with natural sounding voice. Try it free for a week now!

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 tempo and pitch may be adjusted together with a single control. The player is a music looper as well - you can slow down song speed and loop sections of the music for easy practice.

The simple to use audio editor is integrated into a music player with playlists, playing queue, preamp, blance, equalizer, and effects. You can use Music Speed Changer to create new tracks or use it as a real time audio manipulation tool, on-the-go correction tool, and as a music learning aide. It is a musician's and music lovers' complete all in one pocket tool and music player.

As a learning tool, the app helps you slow down and loop difficult parts and raise or lower the pitch of any music to suit your range. Alterations can be saved to a new audio track. The editor features A/B repeat looping, key and BPM detection, and the ability to bookmark parts of tracks by setting markers. These learning tools make the app useful for students and teachers of music, dance, language, and academic subjects.

The app's real-time editor is fully integrated into the music player with the ability to affect its playlists and queue. This means you can play your entire music collection with an upbeat tempo for working out and running or slow down and reverb a selection of your music collection for relaxing. The included audio effects help you create new and interesting soundscapes for taking nightcore and slowed + reverb to the next level.

The Pro version of the app comes with automatic formant shift for natural voice tone correction and independent formant shift controls for creating audio effects.

Music speed changer

Is it possible to update the app to be compatible with iOS 17? I love the app, but it would be cool if there was an equalizer option as well as more speed options. this app is so cool and fun and amazing and awesome and super and phenomenal. it would also be cool if you could set the pitch to +3,600 semitones and -3,600 semitones. it would also be cool if you could set the speed to 0%. please don’t ever get rid of this app because I love it so much and it’s so nice and handy and convenient. Thanks. I give this app a 10-star rating. please keep the updates coming if possible. is it possible to update the app to be compatible with iOS 17.4.1? There’s nothing wrong with the app, but I was just wondering.

Developer Response ,

Thank you. The latest version of the app is compatible with iOS 17. Please make sure you have the latest from the app store here:

The app has an equalizer. Tap the gear at the top of the editor to access the additional audio editing components. Here, you can switch between the default editor layouts or create a custom editor layout with the equalizer and other components that you like to use. Here is more info on the available components:

Almost perfect

The app has amazing features such as VERY realistic reverb settings, a very good equalizer, pitch and speed settings that dont ruin the music quality and a wide range of themes. My only problem with this app is that every single time you leave the app and then come back, it greets you with an Ad. It doesn’t matter if you only switched tabs for one second, you will always get an Ad. I even tested switching back and forth between apps just for a second and every signal time i went back to Music Speed it gave me an Ad. As if that wasn’t annoying enough, you dont have the Ad volume disabled, it clashes with the music you already have playing on the app. This app never use to show Ads this frequently which makes this even more annoying. Especially for users who never had to deal with this prior to whichever update has caused this. It use to show an Ad every now and then but now the app just feels flooded with them. Other than that the app is perfect and runs very smoothly.

Developer Response ,

The ad that shows when reentering the app is currently set to once every 2 hours per user. I can't find any confirmation, but I'm assuming if you opted out of allowing the app to track across other apps, the frequency capping has no way of working.

Never thought I could make my personal composed songs better after finishing them. This app is like icing on the cake. Perfect touch of reverb combined with a lowering of the far right 3 sliders in the equalizer to minimize background noise as well as correct the overly treble sounds. My voice is also naturally lower, so raising the song to be a half-step higher, or even a quarter-step higher (+.50), makes my voice have more of a tone that is easier to listen to. Again, it’s the cherry on top to all of my own creations. I couldn’t go without it, and I can’t believe it’s free. Best app ever
