Audio output is a tone similar to a flute, using a physical model developed from Perry Cook, but re-coded for Csound.

iatt - time in seconds to reach full blowing pressure. 0.1 seems to correspond to reasonable playing.

idetk - time in seconds taken to stop blowing. 0.1 is a smooth ending

ifn - table of shape of vibrato, usually a sine table, created by a function

iminfreq - lowest frequency at which the instrument will play. If it is omitted it is taken to be the same as the initial kfreq.

A note is played on a flute-like instrument, with the arguments as below.

kamp - Amplitude of note.

kfreq - Frequency of note played. While it can be varied in performance, I have not tried it.

kjet - a parameter controlling the air jet. Values should be positive, and about 0.3. The useful range is approximately 0.08 to 0.56.

kngain - amplitude of the noise component, about 0 to 0.5

kvibf - frequency of vibrato in Hertz. Suggested range is 0 to 12

kvamp - amplitude of the vibrato
