免费在线 3GP 转 CDDA 转换器

3GP is a multimedia container developed by Third Generation Partnership Project in 1998 for GSM-based (Global System for Mobile Communications) phones. The container requires little bandwidth, storage space and data usage that is why it is ideal for cell phones. It is a standard container for the files sent using MMS (Multimedia Messaging Service).

A file with the CDDA file extension is a CD Digital Audio file that stores audio in the AIFF format. CDDA files are normally seen only when audio files have been ripped from an audio CD that uses the CD Digital Audio specification. This is most often done through the Apple iTunes program with the Audio CD burn option.
