Neural Audio appointed James D. “JJ” Johnston chief scientist. He joins the company from Microsoft, where his title was audio architect.

The organization says Johnston has been called the “Father of Perceptual Audio Coding” for his contributions to digital audio. His accomplishments during a 26-year career at AT&T Bell Labs allowed for the distribution of digital music and audio over the Internet.

As a technology leader at AT&T Research Labs, Johnston invented several basic techniques used in perceptual audio coding, especially in MPEG-1 Audio Layer 3 (MP3), MPEG-2 Part 7 and MPEG-4 Part 3 Advanced Audio Coding (AAC). He also was responsible for creating the standards used for coding audio-visual information in movies, video and music formats in a digital compressed format.

Johnston retired from AT&T Labs in 2002 and joined Microsoft, where he designed and implemented audio post processing functions for the Windows Vista operating platform.
