Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications. (source: http://opus-codec.org/)
Basically, it's an audio codec designed for encoding high-quality audio such as long podcasts and music streams into a small file size.
Pero hindi lang podcasts ang purpose nito! Due to it's high versatility, Opus can be used for most types of audio, especially music.
As you see, bumaba ang file size! This is very helpful for storing your music in your phone, which has limited space to make room for even more music!
"PERO PAANO ANG QUALITY? BAKA SIRA NA ANG SOUND, DAHIL 96 KBPS LANG EAN EH!"...
