Miraculous, Indispensable, Reliable

I think I’ve had this app almost as long as it’s been around. I’m a singer with a low range for a female. I buy backing or karaoke tracks off iTunes, load them into AudioStretch, and I can lower the pitch without changing the speed. Or I can slow the song down or speed it up without changing the pitch. Then I can export them into another app to save my changes. Miraculous!! Our lead guitarist could only learn songs from listening to them over and over, therefore learning them in my key was difficult until I showed him how to use this app. I’ve told so many musicians and singers about it and they’re all excited to try it. Now I’m telling you: the best music app I’ve ever found. Ever. And tons of features I don’t even use, but you might. Works on my iPad and my phone, and it’s super reliable, never crashed or frozen or lost my work even once in probably 12 years or more. I’d give it 10 stars if I could, a hundred, a thousand.

I couldn’t upload long audio anymore

The app is great but I couldn’t upload long audio anymore since this new update. Please fix it, it was really useful for my work.

Response from developer

Hi Ulan24! It’s wonderful to hear you find the app useful for your work! We understand the recent update affecting long audio uploads has been a challenge. Your feedback is invaluable, and we’re looking into this. If you need immediate assistance, feel free to reach out at bnd.la/contact-us. We appreciate you!

Great app

This app is great ! Minimalist, very efficient and straightforward.
I wouldn’t really mention it like a downside but I feel like it kind of missed a big part of its potential by only targeting musicians trying to transcribe a song from an audio file.
Adding a few basic functions could make it become a nice sampler/granular tool and make it suitable for electronic music makers. Just saying 😇😉
