- An OPUS file is an audio file created in the Opus format (also called "Ogg Opus"), a lossy audio format developed for Internet streaming. It uses both SILK (used by Skype) and CELT (from Xiph.Org) codecs and supports variable bit rates from 6 kb/s to 510 kb/s.
- A CDDA (CD Digital Audio File) is a type of audio file extracted directly from an audio CD. This format is also known as CD-DA, which stands for Compact Disc Digital Audio. It is a standard format for audio CDs established by Philips and Sony in the Red Book specification. CDDA files represent uncompressed digital audio data in a linear PCM (Pulse Code Modulation) format.
