3GP & 3GPP-2
Multimedia containers designed for 3G mobile networks.
Pro Audio Converter can convert audio files to and from 3GP (.3gp) and 3GPP-2 (.3g2) containers.
3GP and 3G2 are containers, not codecs — they hold compressed audio (and video) payloads such as AAC or Qualcomm PureVoice inside an ISO base media file.
3GP (3GPP file format) is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS multimedia services. It is used on 3G mobile phones but can also be played on some 2G and 4G phones.
3G2 (3GPP2 file format) is a multimedia container format defined by 3GPP2 for 3G CDMA2000 multimedia services. It is very similar to the 3GP file format but has some extensions and limitations relative to 3GP.
Pro Audio Converter can store the following audio formats in a 3GP or 3G2 container:
