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.

Customer Reviews

Sound Quality is Low

After finishing a project and once you export and hear your song, the audio plays except the sound is half as lower than before from editing in the app.

I tried switching the Sharing Formats in one of my project's settings and compared a Compressed .M4A File to an Uncompressed .WAV, and how High or Low the sounds were, and all of them were played with the same low volume.

I had even added more Gain to them, it had sounded much louder while editing than when I listened back to both the .M4A and the .WAV .

This makes listeners have to turn their volume almost all the way up in order to hear a project comfortably.

In other words, the rest of this app doesn't have any other issues as I have seen. All effects and features works perfectly.

This is the only thing I would like to have improved.

Undo Arrows

The undo arrows are too close to the projects button. You can easily make a mistake and undo when trying to go to projects. Other than that, perfect app.

I came here looking for one thing but I have to get a membership for it...
