All this dev’s apps are top notch

It would be awesome to finally have something of this caliber but for a multi track editor/recorder.

I believe you can be the one to help podcasters who want to go full ipad only.

With a multi track editor/recorder.

Thank you for the feedback!
I’ll message you on Twitter to brainstorm about how to get this done!

Doesn't work as expected

Keeping it short.

1. Trying to cut out a tiny piece from a 2 hour audio file. Putting the crop handlebars precisely where I need the cut. The exported file is 5-10 seconds off. Tried several times, same result. Made sure I zoom in before cropping to visually check the crop marks are where I want them.

Worst part is once I export, my previous work in progress closes, so I can't easily go back and readjust, I have to open the file again (if it's a large file, wait for it to open), then seek again. I tried one more time, but I won't keep trying.

2. The UI is not as good as it could be. E.g. I move the left seek bracket at the bottom and I expect the playback position to move accordingly - this way I can easily confirm I'm happy with my crop start. In this app I have to manually move the playback. There are some other minor inconveniences. Refer to the Overcast app on a good crop UI.

This was a promising app, but it doesn't work as expected. If the above is not fixed, I'll be requesting a refund.

Basic but helpful!

Like the developer notes, I too was surprised that iOS doesn’t feature a native basic audio editor. This simple app fills the void nicely! Great job
