Liljeryd was born in 1951 in
Stockholm, Sweden. He began his career as a recording engineer. His break came after a
North Sea oil exploration team sought his help to clarify divers’ communication underwater.
New audio compression technology In 1988, Liljeryd also invented a method that clarified sound and picture information electronically, including the approach that carry out the process. This technology eliminated undesirable intermodulation products, providing a linear amplitude ratio. The technique improved on the previous technology of compressing audio formats using “perceptual audio coding”, which eliminated parts of the original file that are missed by the human ear. Liljeryd was a finalist in the
European Inventor Award 2017 for developing a new method of compressing digital audio files called Spectral Band Replication (SBR). This concept, which was produced into a real-world application by a team of engineers, improved existing coding formats such as
MP3 and the Advanced Audio Coding (AAC). This technology allowed better and more affordable digital audio compression, addressing the challenges that came with limited bandwidth and storage space.
Music career Liljeryd also played drums. In 1980, he participated as engineer and percussionist on the
Hans Edler album
Jukebox Graffiti Vol. 4 on the Europe Record label. == References ==
