Hello, I need to convert some AAC files into M4A files and import to iTunes. Is there a free program for a MAC that does this? I'm looking for a program to capture streaming audio from iTunes radio in .m4a format. I was using XStreamRipper which was perfect because it even separates the different tracks played into individual files and (if the radio station is transmitting it) track info like artist, title and duration. However, XStreamRipper is capturing in a format with an .aac extension and the only program I have that will play it (or even open it) is VLC player, but I want the files in iTunes. I have tried a load of audio converters, but none work with these. Can anybody help? Hello, I finally tracked down a program (Sound Converter)that converted the files to .m4a and they play in iTunes, but they play at a "slowed down" rate and the sound is distorted - voices are like watching a slow motion video.
