Hokusai Audio Editor

By Wooji Juice Ltd

Open iTunes to buy and download apps.


Hokusai is a multitrack audio editor for iPhone, iPad or iPod touch. Record or import a track, and make it sound the way you want it to: not just trimming the ends, but full cut, copy, paste and delete, and a suite of filters and special effects available.

"Beautiful clutter-free interface" —

"Hokusai will convince you that audio was meant to be edited with a touch screen — it's just so natural within this app that you’ll find yourself consistently coming back to it." — iOS Music And You

Edit many tracks side-by-side, mix them together, and export to Wave or MP4 format — then transfer them to your computer, send them to another app on your device, or upload to cloud services.

Hokusai is streamlined to give you a clean, clear view of your tracks. Use the familiar pinch and swipe gestures to zoom right in and fiddle with fine detail, or step back to see the big picture. Select pieces of audio. Live "scrubbing" means you can hear the sound under your fingertip as you make your adjustments. And you needn't fear a bad edit with our full undo/redo support — even after closing your project.

Hokusai comes free with a set of useful tools such as fade in/out, normalise volume levels, reverse time, and basic synthesis. If you need more power, you can upgrade from inside the app to add new tools and effects, including: Per-track volume/mute/panning, selecting across multiple tracks at once, presets and favourites, grain synthesis, noise gating, time-stretching, pitch-bending, echo, reverb, modulation (AM & FM), resonance, distortion, grunge, vocal levelling, monster voice, high/low/band-pass/notch-cut filter and more — many of which can be previewed live.

What's New in Version 2.0.9

The last update had a problem that could prevent folks from importing tracks from their Music Library. Sorry about that! This update fixes the issue.

Customer Reviews

Powerful and full-featured

I had assumed that serious audio editing would require a pricey app on my Mac, but Hokusai is quite sophisticated, exploits the advantages of a touch interface, and actually has REAL documentation. It works well with Dropbox and recognizes external microphones.

For those giving it a low rating because they think the free version doesn't do much: what do you expect for nothing? The free version offers enough to confirm it will work with your environment. For less than $10 you get the rest: a fraction of the cost you would pay for many full-featured apps on a Mac.

This Is Perfect

This app is amazing. I love how it's accessible, and very easy to use. I just created a wonderful track that I am extremely proud of, and I can do many more right from my phone. This is so convenient, and I don't know why this app is rated 3 1/2 stars, because it clearly deserves more than that.


I have never been so please with an app that wrote a review. I literally just uploaded the app, my song, and got the job done in less than two minutes. I love that it connects with google drive. That was a huge selling point for me and what I do at school with my students.
