Crop and trim audio, paste in or join files, or just rapidly split one long file into many. Fission is streamlined for fast editing. Plus, it works without the quality loss caused by other editors, so you can get perfect quality audio even when editing MP3 and AAC files.
If you need to convert formats, Fission can do that too, with simple export or batch conversion to the MP3, AAC, Apple Lossless, FLAC, AIFF, and WAV formats.
Don't forget ringtones! Use Fission to make great custom ringtones for all your contacts.
