Sonoma Wire Works has launched the AudioCopy & AudioPaste Software
Development Kit and will be offering it to select iPhone app
developers. The SDK is designed to “take the new copy/paste features
available in the iPhone software to a new level.”

Sonoma Wire Works has developed AudioCopy and AudioPaste
functionality for the iPhone. Software Developers who wish to receive
this SDK may request to join the Mobile Audio Product Interaction
(MAPI) Program. For more info go here:

FourTrack (http://fourtrack.com) has the ability to paste audio
information from a growing list of AudioCopy enabled apps including
Sonoma Wire Works’ InstantDrummer, Retronyms’ DopplerPad, and VOX
3000.

The FourTrack multitrack audio recorder is a songwriting and practice
tool for singers, guitar players, piano players and other musicians
who want to capture musical ideas and record songs on their iPhone
and second generation iPod touch.
