Format Details
AAC
AAC (Advanced Audio Coding) is a lossy audio compression format standardized by ISO/IEC and designed as a higher-quality successor to MP3. It achieves better audio fidelity than MP3 at the same bit rate by using more advanced psychoacoustic models and encoding techniques. AAC is the default audio format for iTunes, Apple Music, YouTube, and all iOS devices, and is supported natively across virtually every modern platform.
OPUS
Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype's SILK codec and Xiph.Org's CELT codec.
