Wave
Spectrum
triangle(frequency, phase)
Returns a function whose input is a time (in seconds) and whose output is a point on a triangle wave. You can create a 440 Hz triangle wave by mapping a time wave to this triangle function, using time.map(triangle(440))
frequency
Frequency of the triangle wave in Hertz (Hz) or cycles per second.phase (optional)
Phase shifts the wave to the left or right. A phase of PI shifts the wave a half-cycle to the right.phase
can either be a number or it can be a wave, as used in Frequency Modulation.
You can find the code for triangle
in the synthesine library.
