Great Substitute for Audacity

I mostly downloaded this app because my laptop stopped working. Audacity was my main app for creating clean radio edits fast, which is something I need to do because I work in radio. This app was perfect, in fact, I’m more of an iPad guy anyway, and this paired with AirPods is just a heavenly combination. Yeah, you can pretty much do anything this app does in GarageBand, but this is perfect for when you need those quick and easy edits. For example, simply tapping and reversing bad words, or replacing it with an instrumental section, feels so much quicker. It makes me a couple minutes to do in this app. GarageBand, because it’s a bit more bloated despite how great it is, probably takes 10-15 minutes. Yeah, this is amazing for my workflow. Some suggestions: first of all, please fix the AI vocal remover. It works great, but it starts with a skip every single time. It seems to be some type of error written into the algorithm or something. Also, please add a TV censor bleep type effect like you can do on Audacity and other apps. Maybe you can already do that on this app, but I haven’t figured it out yet. Other than that, I love it.

Thank you for your trust and support! It's a great honor for professionals to choose our app. 
The first time failure when running the AI vocal remover is often due to system memory warnings. The AI computations require a significant amount of memory, and the first time incomplete processing actually helps release system memory, making the second attempt usually successful. I will explore automatic retry as a solution to this issue, but there are some risks that need detailed testing, as available memory varies on certain devices. 
CONFIRM: I got it, "TV censor bleep" is a sound mask for bad words, it can be supported by generator type effect, I will add this soon. 
Many thanks for your suggestion!

Have used Audacity Windows for many, many years. Yes, there’s a lot of things the PC version does this app doesn’t. I have used…or know about 90% Windows capabilities, so I’m not a novice. But I’ll be darned, on this app, I can’t figure out how to delete a “project”. Tried everything I could think of and can’t get rid of them! Has to be something simple, but I couldn’t figure it out in a half hour of trying. Maybe the IOS crew can explain? Other than that, this app works very well with the editing features as is. No need for me to buy the extras, because 3.1.3 does it all. In lieu of my PC, I use my iPad more, so this app is 5 stars despite my inability to figure out something so seemingly simple…

UPDATE: Thank You Liu Bei for replying. Upon opening the app, the screen displaying the large icons at the opened…instead of the editing screen. I found the the lower right option I hadn’t seen before. It worked as you said.

I’m unfamiliar if Sound Lab is part of Audacity or you license their brand, but your app is truly excellent. I don’t know what the pay features do, but it works fine for my limited audio editing.

I have to say I’ve reviewed apps in the past…maybe 10 or so…and no developer ever responded. As a user, I appreciate it.

I’ve tried almost every editing IOS app at the store and only one other works well, but the EQ is only 5 bands and exports as M4A. Your app is way better in the quality of the edited file as well.

Hi, please click the "Edit Mode" button at bottom right corner of track list, then in Edit Mode, the "Delete" button will shown at bottom left corner. You can select one or more files or projects, and click "Delete" button to remove them.
Thank you for your support, we are working on build app internal WIKI to help new users use the app. 
Hi, Dave. SoundLab is no relationship with Audacity, we have independent codebase. 
Thank you for your high praise, please keep in touch with us at

I wanted to use this App for my little like edits that I like to do of Celebrities on Funimate. I also wanted to use it for editing the songs I like to use it for cool transactions and stuff. But I didn’t expect for this app to have the separation vocals and accompaniment thing. I was so excited. Because I now am able to use it to do like cool mashups of songs that would be cool to put together. I’m happy to have this and thank you to the people who own this app. I appreciate your hard work in making this app. You guys did an amazing job on putting everything in this app (that doesn’t cost a single dime or penny!) to make sure to give those talented people a chance to make beautiful things!! You guys have so much of my support and love!! Keep up the good work!
