Aliasing is also sometimes referred to as fold-over. When a key is released, it will return to zero at the rate set by the release parameter.Īliasing: Unwanted frequencies produced when harmonic components in the audio signal being sampled by a digital recording device or generated within a digital sound source are above the Nyquist frequency. The envelope will remain at the sustain level as long as the key is held down.

When a key is pressed, the envelope generator will begin to rise to its full level at the rate set by the attack parameter, upon reaching peak level it will begin to fall at the rate set by the decay parameter to the level set by the sustain control. The Attack, Decay, and Release parameters are rate or time controls. An envelope generator is sometimes called a transient generator. Hammond organs and similar instruments make the most use of simple additive synthesis.ĪDSR: Attack, Decay, Sustain, and Release are the four parameters found on a basic synthesizer envelope generator, and they match the physical attributes of naturally occurring sound.
Envelope shapers and filters can further process these waveforms.
Sonorus STUDI/O is a ADAT Lightpipe soundcard.Īdditive Synthesis: A method of synthesis that builds complex waveforms by combining sine waves with independently variable frequencies and amplitudes. Lightpipe is used with ADAT machines and is incorporated in numerous soundcards and multiple AD/DA converters. The ADAT optical connections for transferring the digital data 8-tracks at a time are used in a wide range of products from many manufacturers.ĪDAT Lightpipe: A digital interface that allows 8 individual tracks to pass through an optical (Toslink) cable. It records eight tracks digitally on a standard 1/2″ SVHS video cassette and is currently a 20-bit digital format. ADAT: A trademark of Alesis Corporation for its modular digital multitrack recording system released in early 1993 and stands for Alesis Digital Audio Tape.
