Description

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.

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.

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.

Efficient but buggy

This is an amazing app! I’ve been using it to cut my music and it works miracles (most of the time). There are some times when I would select a region to begin cutting, and then it would just automatically slide to some other spot. Or I would slide the cutter to cover the region I want to delete, and then it would just shrink to where I selected it. Over and over again. This is probably the only complaint I have regarding this and it is rather frustrating to deal with. Please take this into consideration and hopefully make changes to fix this bug. Thank you for reading

Hello! Hokusai automatically adjusts your selection to the nearest "zero crossing" to ensure a clean, glitch-free edit, but you can switch this off if you don't want it to. Go to the Tools menu > Settings > Snap to Zero Crossings and set it to "Never" to switch this behaviour off. If you need more information about zero crossings and why they're important to editing audio, please get in touch via the Contact Customer Support link in the Tools menu. Thanks!
