square wave
A rectangular waveform that alternates between a positive value and
a negative value. Its frequency spectrum includes all of the odd
harmonics and has higher harmonic content than a triangle wave.
stereo
Stereophonic; having two audio channels.
threshold
The Envelope Follower’s threshold is an amplitude level used to gate
the Envelope Follower’s output. All amplitude envelope values below
the specified threshold percentage will be greatly attenuated;
amplitude envelope values above the threshold will be unchanged.
Generally the threshold is set to 0%, making it inactive.
timbre
A sound’s tone color, which is a function of its harmonic content.
time constant
The Envelope Follower’s time constant is used to specify how
quickly the output tracks variations in the source signal’s amplitude.
A time constant of 20 ms means that half of the information used in
calculating the current Envelope Follower value comes from the last
20 ms, and half comes from all previous samples.
Selection of the optimal time constant is a tradeoff. Short time
constants are responsive but rough; long time constants are smooth
but sluggish.
tremolo
A low-frequency variation in a sound’s amplitude envelope. In SFX
Machine Pro, you can create tremolo by amplitude modulating a
sound with a sine or triangle wave in the 5 to 9 Hz range.
triangle wave
A waveform with alternating positive- and negative-sloped ramps.
Its frequency spectrum includes all of the odd harmonics.
triggered wah
A wah-wah filter whose cutoff frequency opens and closes in
response to the signal’s amplitude envelope.
