An audio coding format [1] (or sometimes audio compression format) is a content representation format for storage or transmission of digital audio (such as in digital television, digital radio and in audio and video files). Examples of audio coding formats include MP3, AAC, Vorbis, FLAC, and Opus.
CD audio is 44100 samples per second. The number of bits per sample also depends on the number of audio channels. The CD is stereo and 16 bits per channel. So, multiplying 44100 by 32 gives 1411200—the bit rate of uncompressed CD digital audio. MP3 was designed to encode this 1411 kbit/s data at 320 kbit/s or less. If less complex passages ...
MPEG-1 Audio Layer II is the audio format used in Digital Audio Broadcast (DAB), a digital radio standard for broadcasting digital audio radio services in many countries around the world. The BBC Research & Development department states that at least 192 kbit/s is necessary for a high fidelity stereo broadcast:
The 'Music' category is merely a guideline on commercialized uses of a particular format, not a technical assessment of its capabilities. For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint.

The IC3 Digital Literacy certification (Internet Core Competency Certification) Digital Literacy certification is a global benchmark for basic computer literacy, including operating systems, hardware, software, and networks. [1] The IC3 certifications test concepts and skills that apply to almost any school or career pathway.
Digital audio formats such as WAV, mp3, and ogg are used when the audio itself is part of the analysis. Lossy formats such as mp3 and ogg work well with the human ear but may be missing crucial data for study. Additionally some encodings create artifacts which could be misleading to any automatic analyser.
A student can be a successful digital citizen with the help of educators, parents, and school counselors. [33] These 5 competencies will assist and support teachers in teaching about digital citizenship: Inclusive I am open to hearing and respectfully recognizing multiple viewpoints and I engage with others online with respect and empathy.
