Audio manipulation like MIDI
On Habré, there were mentions about new interesting photo or video processing capabilities , but the same thing happens in the audio environment. Not noticed that our "stars" in recent years have become better to fall into the notes? :)
The essence of the technology: even polyphonic audio can already be edited as MIDI - to change the pitch, duration, start time, volume. Watch the video.

The video shows the program Celemony Melodyne . It exists quite a long time ago, but if it used to allow only monophonic parts to be played, now it can put whole chords into parts (the technology is called direct note access).
A version with these features will appear at the end of the first quarter of 2009 and will cost 400 bucks.
Update:
The beauty of this thing is two things.
1) In general, everyone knows a simple algorithm for changing the pitch - if you turn the record or film faster, the pitch rises. If slower, it goes down. Yes, you know these funny sounds.
The problem is that this also changes the playback time. In this case, this is unacceptable, so the algorithm is much more complicated. Its high-quality implementations appeared not so long ago (for example, in Cubase only from SX 3.01 version).
But much more interesting than the other ...
2) An audio file is information about a single large wave made up of smaller waves. And the notes are not represented by any one frequency - they have harmonics that are layered on each other. This thing allows you to select specific notes from one big wave and edit them independently in a convenient and intuitive interface.
As Reey comments: “damn, it’s also as cool as breaking a movie into 3d objects with animation - I never thought it was possible.”
Well, yes, you can still draw an analogy with Photoshop - it's like to restore the original layers from the final image.
