How to split MP3 audiobooks easily


A large-sized audiobook can make great annoyance to us. Most of times, we wish to get back to re-enjoy our favorite parts of an audiobook, but only to find that it is really hard to find those parts. The harder you try, if unluckily you cannot retrieve the part, the more annoyed you get. The best solution is to chapter the audiobooks to our personal preference, which also means we determine the time interval of a chapter for the audiobooks. Sounds cool, isn't it?

Macsome Audio Book Converter boasts its function of splitting audiobooks. No matter .AA audiobooks form, or M4B, M4A audiobooks from iTunes Store, all can be converted and splitted by this excellent audio book converter.

Actually, prior to splitting audiobooks, the software converts .AA, M4B and M4A audiobooks to MP3, WAV or AAC format first (If you don't wish to change their format, you can set the output format as Same as source, and then what we get is one large-sized audiobook with its original format which is waiting for us to chapter). After the conversion can we start to split the audiobooks. The whole process will not take much time, and just wait a minute, we can get audiobooks with new chapters by ourselves. Thus, we make it possible to split .AA audiobooks, M4B audiobooks and M4A audiobooks.
