Where OGG and Opus Files Come From
Shared or exported voice notes are .opus files. On Android they also sit in the WhatsApp Voice Notes folder.
Telegram voice messages save as .ogg from the desktop app; Discord voice messages are OGG files too.
Audacity, OBS and Linux recorders often export Ogg Vorbis or Opus.
OGG and Opus at a Glance
Ogg is a container; Opus and the older Vorbis are the codecs inside. Opus was built for speech at low bitrates, which is why messengers use it.
