What is Opus?
Opus is a lossy audio format created in 2012 by the Xiph.Org Foundation and then standardized by the IETS (Internet Engineering Task Force). The Opus format is usually used by music streaming services and messaging apps with voice-recording features. We’ve provided specifications below for the Opus file type and a list of programs that can play Opus files.
In Opus files, audio data is stored in an OGG container. Opus files are encoded with SILK (codec developed by Skype) or CELT (codec created by Xiph.Org) and support variable bit rates (6-510 kb/s). We’ve listed below some of the programs that support the playback of Opus files. Refer to this list if you’re not sure how to open this type of audio file.
VLC, Winamp, SMplayer, and AIMP
What is AAC?
Advanced Audio Coding
Fraunhofer, Dolby, Sony, and others
AAC, which stands for Advanced Audio Coding, is a widely used format for audio compression and the most common audio format for Apple devices. The AAC file type was created as a substitute for MP3. Generally, AAC provides better sound quality than MP3 at similar bitrates. Many devices, including Apple and Android, support AAC. But if you want to play your audio collection on another device without iTunes, your best option is to change the format of your files to MP3, which is still used almost everywhere. Check the list below if you’re not sure how to open AAC audio files and which programs support playback of these files.
.aac, .m4a, .m4p, .m4b, .mp4, .3gp
Files with the AAC specifications enable temporal noise shaping, non-uniform sampling, and bitstream reformatting for 16 stereo, 16 mono, 16 low-frequency channels, and 16 annotation channels in a single bitstream. In 1999, the AAC format was included in the MPEG-4 Part 3 format, after which AAC added support for audio object types and permanent noise replacement technology. AAC is currently described in the ISO / IEC 14496-3 standard.
