Note:
- Extreme pitch and tempo changes (for instance 24 semi-tones, which is quite a lot!) can lead to noise.
- Voice reduction quality depends on the input. It works best with little compressed music and assumes that voice was recorded in mono and later mixed into the stereo channels (which is the case for a lot of music recordings)

### 5/5 — 😤😤😤😤

*2026-03-28, version 1.89*

DONT EVER DISCONTINUE THIS APP!!! Keep this on here forever

### 5/5 — I’ve had this app all my life practically

*2025-12-08, version 1.89*

This keeps me going in life, couldn’t imagine my life without it. I love music, use this app just about everyday, it’s excellent.

### 5/5 — I love this app.

*2024-11-25*

I VERY rarely make reviews - but this app deserves it. I have had this app for so many years and I absolutely love it. Linking my iTunes downloaded songs to this app has never been a bother. I love being able to change the pitch of every song I love, even now like 7 years after I bought the app to begin with. Some people have complaints about the music stopping when closing their phone- I do have the same issue, but it continues playing through earphones. I understand the frustration, but having AirPods has made that issue completely nullified. This app is so simplistic, yet has helped me with so manny audio adjustments when I’ve needed it. I sincerely hope ASC doesn’t shut down. This app has almost completely changed my view on all Apple devices. I’ll always remember being on my iPhone 6 series vibing with the adjustments ASC made. I know it’s pricey downloading every song you love, but this app makes it worth the cost. I really hope this app doesn’t shut down in the newer iOS, otherwise I’ll use it forever.

### 3/5 — ↘️↘️

*2023-11-08, version 1.89*

Uygulama açınca atıyor

### 1/5 — ITunes library only

*2023-10-10*

I paid and clicked "save" then a message popped up, " file available via ITunes share".
It didn't save to the folder on my phone and I can't access it unless I have iTunes, which I hate.

### 2/5 — Cant add music

*2023-04-28, version 1.89*

Adding music from Dropbox is broken.

The inly other option is adding from the music gallery bu who uses that?

Fix adding from dropbox and implement adding from files on the phone.

### 1/5 — Doesn’t import mp3 files from files

*2022-08-13*

Doesn’t import mp3 files from files

### 2/5 — App collapses in iOS 15.5

*2022-06-16, version 1.89*

Very useful app but frustrating too as lately it started collapsing and sound becomes staticky 
Please fix this issue.
Thx

### 5/5 — Great for Group X Instructors!

*2022-04-22*

Needed something simple to use for Pitch Control (speed control) in my Group X classes. This works great! Just add the Playlist you need from your music library and adjust the Tempo (speed) as needed. The next time you need it, it will be there ready to go. I added all of my Aerobics Playlists and the correct Tempo is saved in the app where you last left it. Now I can hook up my phone to the Stereo at the Gym and play my music at whatever speed I need. This is a game changer! Thank you!

### 4/5 — Pretty good

*2022-02-26*

I don’t know if the developer is left handed but I’m right handed and when I go walking and listen to music my thumb doesn’t reach the pause button on the bottom left so if there was an option to switch around the buttons that would be great. It’s just easier.
