OPUS (Opus Interactive Audio Codec) is best for real-time voice communication, live streaming, and low-latency audio where quality at low bitrates is critical. MP3 (MPEG-1 Audio Layer 3) is best for distributing music and podcasts with the widest possible device compatibility and reasonable file sizes. Key tradeoff: OPUS's advantage is best-in-class quality at every bitrate from 6 kbps voice to 510 kbps music, with only 2.5 ms codec latency — unmatched by any other codec, while MP3's advantage is absolute universal compatibility — every audio player, phone, car stereo, and bluetooth device ever made supports mp3.
