I’ve seen plenty of tools that turn an iPhone or iPod touch into a high quality digital audio recorder. Some, like the Blue Mikey are simply external microphones that sound a heck of a lot better than that puny mic you talk into when making phone calls. Others, like the Alesis Pro Track give you high quality mics, XLR inputs, VU meters, and volume knobs.
But while these tools let you make high quality recordings on an iPhone, you still need decent software to store those recordings or edit them.
Of course, no iPhone app is going to replace a full featured desktop audio workstation like Pro Tools or Adobe Audition. But there’s a new audio editor for the iPhone that does a surprisingly decent job of giving you the basic tools you need to record, edit, and mix audio on the go.
Monle ($9.99, iTunes) is a 4 track non-linear audio editor. You can use it to record audio or import WAV files. But more importantly, you can arrange audio on a timeline, adjust volumes, split files, and create fades.
