A System-on-a-Chip for Audio Encoding
https://web.cecs.pdx.edu/~mperkows/CLASS_573/573_2007/JacobBower.pdf
completely self-contained digital audio encoder, based around a high-quality general purpose audio compression algorithm called Ogg Vorbis. The resulting audio encoder is able to operate 33% faster than the original software only algorithm, and when running at 25MHz on FPGA hardware is able to achieve compression of 8KHz, mono, audio data in real-time.

A system-on-a-chip for audio encoding Abstract: This project covers the development of a self-contained 'system-on-a-chip' (SoC) design which allows the lossy compression of digital audio data. Primarily, this is achieved by the creation of a general purpose extensible SoC framework, based around an off-the-shelf central processing unit (CPU) core.

MPEG-2 encoder, the SAA6752HS, is a highly integrated single-chip audio and video encoding solution with flexible multiplexing functionality. With our expertise in two critical areas for consumer video encoding, noise filtering and motion estimation, we have pushed the boundaries for video quality even further, providing enhanced quality for
Audio codec - Wikipedia
https://en.wikipedia.org/wiki/Audio_codec
An audio codec is a device or computer program capable of encoding or decoding a digital data stream (a codec) that encodes or decodes audio. In software, an audio codec is a computer program implementing an algorithm that compresses and decompresses digital audio data according to a given audio file or streaming media audio coding format. The objective of the …
