What is a 3GPA file?
A 3GPA file is a multimedia file developed by the 3rd Generation Partnership Project (3GPP). It stores video and audio streams that are saved in an audio and video container format. 3GPA files are used for transmitting audio and video between 3G mobile phones and over the Internet.
The 3GPA format stores audio streams as AMR-WB, AMR-WB+, AMR-NB, HE-AAC v1, AAC-LC, or Enhanced aacPlus. 3GPA files are the same as .3GP files but not as common.
