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.

Sorry for the delay. I was able to get my tools purchase restored. Appreciated!
Hello! We stopped selling the Hokusai 1 Tools Pack a couple of years ago, but if you previously purchased it, you can still use all of its features in Hokusai 2.
I ran a search of our email archives and didn't find any queries about the Tools Pack since 2016, so I don't know what the issue is that you've run into, but if you need to restore a previous purchase, you can go into the Upgrade panel and tap "Restore Purchases". You need to be signed in to the App Store with the same account that you originally purchased with, so that the App Store can find the purchase and restore it for you. If you aren't sure which account you purchased from, you can check your purchase history — see https://support.apple.com/HT204088 for details.
