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" — TouchProducer.com
"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.
Fixes a compatibility issue when run on iOS 13.
Ratings and Reviews
Great app with some bugs
I've been using this app for over a year or so and it has been great until the last update to version 2 where it won't resume play if some other app took control of the audio, or even if I get a call and try to play again, it won't and I have to restart the pp to get it to resume.
Another issue with it is when you copy and paste the entire audio of 3 minutes long or so on the same track a few times to get a loop effect and play the audio, if goes all static after an hour or so.
Besides the two issues, it has been an awesome tool for my editing needs so far , loaded with great features that would be under premium option on some other apps.

The only app I’ve ever paid money for!
I’ve been in the music business for 50 years and I have produced major label quality CDs and worked internationally. I’ve been told that I have good years and know how to create unique sounds. I especially love to record out of doors and capture the sounds of the city or the songs of birds etc. this app has become my go to, and other than my DAW, most of my projects will start with Hokusai 2.
It is absolutely intuitive, and with very few exceptions does pretty much everything that I wanted to. I do have big hands and sometimes I get frustrated with the size of my phone screen. But then I got an iPad and man oh man did I go to town. I started with a free app but then after about a week I was like “I must have more!” One of the more fascinating tools I use is the noise reduction where in you sample a tiny section of NOISE and then run it through the program and that noise is removed. It’s really fantastic and I’ve communicated with the developers and they’re really good about getting back to me. They’re very nice people and I’ve been sharing my ideas with them and one thing I would like to reiterate here is it be nice to have a return to zero (RTZ) function as well as a mute button on each track. With this app and the trio of aps from Amplify one almost doesn’t need a DAW to make great music.
Closest thing to Audacity in iOS
If you like the destructive editing of Audacity, Hokusai will fit the bill. Hard to believe this app is free. With a proper USB interface and connector, you can record and edit high quality audio on your phone. Also good support - my questions were answered promptly so the app is in active development as we speak unlike most other freeware. Editing is a breeze and feels particularly fluid on an ipad - you’ll be dragging to highlight and edit. Cloud uploads are painless allowing to have a truly mobile recording experience. What this is not: this is not a full DAW. There are other apps for that. But a competent sound recorder program it is - for more options, upgrade to the paid version.
