OGA is the audio-only Ogg container — same Vorbis/Opus audio as OGG with a different extension.
Typical use: Converting OGA to MP3 sidesteps the device-support gaps of the Ogg family.
About the OGA format
OGA is the Ogg container's audio-only extension: the same Vorbis (or Opus/FLAC) stream as an OGG file, renamed to signal "this is music, not video". Wikipedia's audio files and old game rips commonly use it.
Functionally it is an OGG — and it inherits the same hardware-support lottery. Converting OGA to MP3 ends the guessing game on phones, car stereos and anything without an Ogg decoder.
