About OPUS and MP3
OPUS: Opus is a modern, highly efficient codec used by WhatsApp voice notes, Discord, Zoom and WebRTC calls. It sounds excellent even at very low bitrates.
MP3: MP3 is the most widely supported audio format in the world. It uses lossy compression to make music and voice files small enough to share, while keeping quality good enough for everyday listening.
