Audioforge is the Swiss army knife for audio files on iPhone and iPod Touch. Edit the wave form directly just by touching it. Set selections to copy and paste within files or even paste from another file. Dynamically change volume for fade in effects or the remove unwanted clicks. Adjust stereo balance and set it to the far left channel for the beginning of the track continuously transferring over to the right channel for the end. Add stereo widening effects or bring it all to together to make is sound mono. Add high pass and low pass effects to start an intro, simulate a telephone conversation or just distort your sound.
To improve your experience with the markers, touch and hold the marker for about 0.5 seconds before dragging it. This will ensure you are not scrolling the wave form but actually moving the marker.
Upload your audio via wifi (mp3, im4, wav, aif format), or use Audiocopy and paste. If you own AudioView, you will also be able to exchange audio with Beatmaker. On iOS4 you can also import files directly from the iPod library.
Real time effects include:
