3GP Audio is a component of the 3GP multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G mobile phones. It typically uses AMR, AAC, or HE-AAC codecs for efficient audio compression, suitable for limited bandwidth and storage on mobile devices.
History
The 3GP audio format was introduced in 1998, and was designed to optimize multimedia storage and transmission over 3G networks. It uses codecs such as AMR-NB (Adaptive Multi-Rate Narrowband), AMR-WB (Adaptive Multi-Rate Wideband), and AAC (Advanced Audio Coding) to ensure clear audio quality at low bitrates. This format was crucial in the early 2000s for mobile multimedia services, enabling efficient audio streaming and storage on mobile devices. While its use has declined with technological advancements, it remains relevant for legacy applications.
