If you need to create an audio recording, e.g., to record a lecture, etc., you can do so on a Mac OS X system using the QuickTime Player application that you should be able to find in the
/Applicationsdirectory on the system. When you have completed recording, you can save the file in the MPEG-4 Part 14 multimedia container format as a .ma4 file. If you wish to convert the file to another format, you can convert it with iTunes or the afconvert utility that comes with the OS X operating system.
