I'm wondering how can I crop some part of voice and audio and make them together in single file using Objective-C code.
Should I use C++ library?
Want to convert avaudiorecorder to data and choose some parts.

Open the files, extract the data, find what you want, combine, construct new file header, write file. Simple. – Hot Licks Nov 28 '12 at 13:29

The file formats are on the web, if you Google for them. It's a SMOP. – Hot Licks Dec 01 '12 at 13:40
