Reforge - Waveform Editor app for iPhone and iPad

Reforge for iPad is the Swiss army knife for audio files on iPad. Edit the wave form directly just by touching it. Set selections to cut, copy and paste within files or even paste from another file. Set the selection to trim unwanted parts of your audio off.

Record right in the app. Zoom-in down to sample level.

Automate volume changes for fade in effects or 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 enhance your sound.
 
Use control markers to automate the effect levels. Add as many markers as you need by double tapping on the waveform. Move them around to generate the changes to the effect you need.

*** To improve your experience with the control 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. ***
