About the OPUS format
Opus (IETF RFC 6716, 2012) is the codec that ended the argument: it merges Skype's CELT and Xiph's SILK into one royalty-free format that is simultaneously the best low-latency speech codec and a superb music codec. WebRTC calls, Discord, WhatsApp, WhatsApp calls, YouTube's low-bitrate streams and Zoom all run on it.
At 6 kbps it keeps speech intelligible; at 128 kbps it is transparent for music; latency can dip below 5 ms for live conversation. Its weakness is hardware: dedicated chips and some car/hi-fi devices still lack it, and standalone .opus files are less recognized than MP3 on random devices.
+ Strengths
- ✓Best quality-per-bit across speech and music
- ✓Ultra-low latency — built for live calls
- ✓Royalty-free IETF standard
! Limitations
- −Hardware support still incomplete
- −Not a mastering or archival format
About the AC3 format
AC3 (Dolby Digital) is the surround format of the DVD era and still the standard audio track on Blu-rays and broadcast TV. It carries 5.1 channels at 384–640 kbps — built to make home theatre rumble. Extracted from discs or remuxed downloads, .ac3 files are common on everyone's drive.
Phones and most editors do not decode it. The practical move is conversion: MP3 for listening, WAV when the audio is destined for editing. Both keep the mix you know — just in a format every device handles.
+ Strengths
- ✓True 5.1 surround from disc sources
- ✓The DVD/Blu-ray audio standard
! Limitations
- −Almost no mobile or web support
- −Lossy — downmixing loses the surround image
