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.

How to remove upload error

This upload error is not letting me upload the file anywhere. Please tell how to remove it

Developer Response ,

Hello! I'm sorry to hear that you have run into a problem uploading a file. If you're encountering an error during the upload itself, unfortunately this isn't something I can help you with, as the upload is performed by the app for the service you're uploading to, not by Hokusai. On the other hand, if the problem you're encountering is while preparing the audio file for upload, please let us know directly by using the "Contact Customer Support" link inside the app's Tools menu, and tell us what kind of error you're seeing, so we can investigate that for you. Thanks!
