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.

Ratings and Reviews
Doesn’t do what I need, due to copy write
Wanted this to slow songs down and analyse them for learning to play them on my guitar! Every song from my library won’t upload due to them being protected!
I understand it to an extent, but is useless for anyone else trying to do the same thing.
Developer Response ,
Hello! I understand your frustration, but unfortunately this isn't something we can help with — if the songs in your Apple Music Library are Copy Protected, we're not allowed to import them. It's against Apple rules and (in some places) may be against the law. Hokusai can import non-Copy Protected songs from your Music Library and many other places such as iCloud Drive, Dropbox, Google Drive, or by copying songs into the app, but we can't help you break Copy Protection.
I have been a working voice actor for about six years now. In that time I have created numerous home studios with expensive processors, computers, microphones and acoustic treatment.
One thing I have always found to be near impossible is to put together a portable at a reasonable price. I’ve used my old Zoom H2 and a laptop at times and the results have been good but the laptop has always been a pain in the neck to cart about.
I’ve had Hokusai for a year or two and it was clear from the start that there was potential to use this app to make money from my voice no matter where I was in the world. The limitations though were that the iPads I had previously were difficult to connect to microphone and didn’t really have the grunt to cope with the intensive audio editing required in my work.
All this changed with the iPad Pro 2017. Now I can hook up my H2 via the usb 3 connection kit and it will record directly into Hokusai. The sound quality is good enough for professional purposes.
The processing power of the iPad Pro turns Hokusai into as good a tool as the Adobe Audition software I use at home and the cherry on the cake is IOS 11 which allows me to deliver, store and archive the audio I record and edit with Hokusai.
The effects such as noise removal are superb. I would go so far as to say better than Adobe.
If you are looking for the best in IOS audio recording and editing, don’t waste your time elsewhere, Hokusai is everything you need and more.
I briefly tried the freebie version on a test file and finding it workable, went for the paid version. All my previous years of editing audio files have been done on a desktop box, so this interface needed a little familiarisation but eventually got there. Second file was a recently unearthed 48 year old vinyl recording of my late mother, so this software got a decent workout. A lot of useful features and I think it will take some time to use/try them all, some certainly need careful thought. This is not software for those that need instant gratification but for those who are happy to work for good results.
Only improvement I’d like to see is knowing what will be undone/redone at the point of hitting the icon.
As I really prefer a desktop app, it would be great to see this ported by Catalyst to macOS.
Excellent app, if you need to edit audio files.
