The Haas Effect was discovered by Dr. Helmut Haas back in 1949, and it is somewhat of a psychoacoustic phenomenon. This law, also referred to as the “precedence effect,” states that if a sound follows another sound within 40ms (below the threshold of a human’s echo…
Oscillator Sync
One major feature that you’ll find on a variety of different synthesizers is oscillator sync. This refers to the process where one oscillator restarts the period of another oscillator, which results in both having the same base frequency. The timbre on the synched…
Wave Field Synthesis
Wave Field Synthesis, commonly referred to as WFS, is a technique for spatial audio rendering. Users can create acoustic environments in the virtual realm. WFS involves producing “artificial” wave fronts that are synthesized by a number of individually driven speakers…
ADAT Lightpipe
The ADAT Lightpipe, officially known as the ADAT Optical Interface, is a standard for transferring digital audio between equipment. This interface was originally developed by Alesis. Lightpipe gets its name from the fiber optic cables it uses to carry data. Toslink…
Equal Loudness Contour
For those who don’t know, the equal-loudness contour is the measurement of sound pressure over a range of frequencies in the spectrum where each is perceived at the same volume as the next. ‘Phon’ is the measurement for these loudness levels in reference to these equal…
Dynamic Range Compression
Dynamic Range Compression (DRC), also referred to simply as “compression,” is a procedure in which an audio signal’s dynamic range is lessened. Compression can be used in many different situations, including broadcasting, live sound reinforcement, and sound recording to…
