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.

Noise Reduction Feature ACTUALLY WORKS!
This app is super intuitive and very easy to learn. The basic version is pretty solid by itself, but upgrading to premium was worth it just for the noise reduction feature alone (the main reason why I downloaded this app). I tried it twice, the first time it took away all the background noise but my voice sounded like it was in a cave, and the second time it took away all the background noise and my voice was left sounding exactly the same. So there was some trial and error involved, but not much. The AI is not perfect, but that’s OK. It has worked for me once for so far, and that is more than I can say for any other voice recording app!
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!
