45 RPM

By Tim Mahony

This app is only available on the App Store for iOS devices.


With 45 RPM you can open any song from your music library and simulate the faster playback speed of a 33 rpm record at 45 rpm or the slower speed of a 45 rpm record at 33 rpm.

As most vinyl enthusiasts will have discovered, accidentally playing a record at the wrong speed can lead to some surprising results and quite exciting discoveries hidden within the records you thought you knew so well.
Why should people with turntables have all the fun though? Now you can load any song from the music library on your device and play it back like a 33 rpm record at 45 rpm (faster) or a 45 rpm record at 33 rpm (slower).
The shift in pitch isn't huge (a bit more than a 5th in musical terms) so sometimes the result is quite cool, especially with instrumental music. It also works really well when speeding up singers with low voices or slowing down singers with high voices.

NEW! Click the 'Share' button to let people know what you are listening to on major social networks such as Facebook, Twitter and Sina Weibo as well as text or email.

What's New in Version 1.61

- Updated music selection list to exclude songs in iTunes cloud. Only songs that have been loaded to the device will be displayed.
- Minor bug fix.

Needs update

I love this app, I use it all the time for musical exploration, and I was devistated after updating my phone and finding I can’t use it any longer. Please update it. I know it’s been three years since you have and probably forgot about it but I need this app, and I payed for it.

Functions Perfectly!

I enjoy speculating about what a song will sound like at a higher or lower RPM. This app lets me hear it with my ears.

The app functions exactly as stated by allowing you to adjust the playback speeds of songs stored on your device. It even simulates the effect of changing speeds on a record player by ramping the pitch up or down! (A nice touch.)

Suggestion 1: If possible, allow access to voice memo recordings for added fun.
Suggestion 2: Add support for 78 RPM
