mp3TrueEdit touch

With mp3TrueEdit you can easily record, edit, play and create MP3 and AAC audio projects that allow you to save your work at any time. Then, you can then ‘export’ your edits without any quality loss at all! During playback you can also change the pitch or tempo to suit your needs.
You can cut, copy, paste, delete and crop audio, and now change volume, all quickly and easily and all for free. You can also purchase an upgrade to enable extra functions too, such as fade-in and out, inserting silence and other silencing effects. There is even an automatic normalize function to maximize volume levels without any distortion. The upgrade also includes the ability to split audio into tracks and tag and export them as separate files as well as a new 'convert' feature that allows you to change the audio file format and settings and also to save changes to the pitch and tempo.
As well as this the 'Pro' version of mp3TrueEdit allows you to join audio files of the same type (by appending audio) or split audio into separate files by creating and tagging tracks and exporting them or by exporting selected audio regions in the free version.
