Because the recommended audio data rate is rather low, some authorities recommend using High Efficiency AAC (HE-AAC), rather than the Low-Complexity profile (AAC-LC), because HE-AAC delivers superior quality at lower bitrates.
HE-AAC Multichannel is the only native surround audio codec in Android and enables the playback of high-quality 5.
