What is a Opus file?
Opus is the modern voice and streaming codec behind WhatsApp voice notes and Discord calls — excellent quality at tiny file sizes, but not widely supported by standalone music players or older devices.
First released in 2012 by Xiph.Org / IETF, it uses lossy compression and no transparency, which makes it best suited to voice messages from WhatsApp, Telegram and Discord, and low-latency streaming.

Opus: frequently asked questions
Why won't my WhatsApp voice message play in my music app?
WhatsApp saves voice notes as Opus, which most music players and older phones don't support. Converting to MP3 makes it playable everywhere.
Is the conversion private?
