What is "qsound"

QSound is the original name for a positional three-dimensional (3D) sound processing algorithm from QSound Labs that creates 3D audio effects from multiple monophonic sources and sums the outputs to two channels for presentation over regular stereo speakers. QSound was eventually re-dubbed "Q1" after the introduction of "Q2," a positional 3D algorithm for headphones. As the company's spatial audio algorithm family grew, and multi-speaker surround system support was added to the positional 3D process, the QSound positional 3D audio process became known simply as "Q3D". QSound was founded by Larry Ryckman (CEO), Danny Lowe and John Lees. Jimmy Iovine served as SVP of Music and Shelly Yakus as VP of Audio Engineering in its formative years.
