Developer Woojijuice has announced Hokusai – a new multi-track audio editor for the iOS.

Here’s what they have to say about Hokusai:

Hokusai is a multi-track audio editor — like a word-processor for sound. It’s for iPad, iPhone and iPod touch, subtly adjusting its interface to fit the different devices.

You can grab audio from a bunch of different sources — recording in to it, importing from various file types via USB or Dropbox, transferring recordings from Sylo Synth or other apps, using the built-in synth tools, and so on.

Then, you can chop and change to your heart’s content: select bits, cut and paste them around, apply all sorts of different filters, mix down tracks… the full version of Hokusai includes over 35 tools for munging audio.

When you’re happy with it, export to wave or AAC/M4A (MPEG4) format, again via USB or Dropbox or by sending it to other apps.

It’s still currently in development, but Woojijuice has shared this sneak preview:

A quick preview of our Hokusai audio tool in action on the iPad.

First we import a field recording (made earlier using Hokusai on iPhone, and transferred to the iPad via Dropbox).

I trim out my favourite takes, then combine them together using multiple tracks and the “hand-on editing” feature, where, instead of cutting and pasting, you simply “lift” your audio up off the track and slide it into place.

Mixing the tracks back down, I apply a series of special effects, then export the result as an MPEG 4 Audio file to Dropbox, and it appears automatically on my desktop computer a few seconds later.
