print iarg[, iarg, ...] display xsig, iprd[, inprds[, iwtflg]] dispfft xsig, iprd, iwsiz[, iwtyp[, idbouti[, iwtflg]]]
These units will print orchestra init-values, or produce graphic display of orchestra control signals and audio signals. Uses X11 windows if enabled, else (or if -g flag is set) displays are approximated in ASCII characters.
iprd – the period of display in seconds.
iwsiz – size of the input window in samples. A window of iwsiz points will produce a Fourier transform of iwsiz/2 points, spread linearly in frequency from 0 to sr/2. iwsiz must be a power of 2, with a minimum of 16 and a maximum of 4096. The windows are permitted to overlap.
iwtyp (optional) – window type. 0 = rectangular, 1 = Hanning. The default value is 0 (rectangular).
idbout (optional) – units of output for the Fourier coefficients. 0 = magnitude, 1 = decibels. The default is 0 (magnitude).
iwtflg (optional) – wait flag. If non-zero, each display is held until released by the user. The default value is 0 (no wait).
inprds (optional) – a scaling factor for the displayed waveform, controlling how many iprd-sized frames of samples are drawn in the window (the default and minimum value is 1.0).
print – print the current value of the i-time arguments (or expressions) iarg at every i-pass through the instrument.
display – display the audio or control signal xsig every iprd seconds, as an amplitude vs. time graph. Higher inprds values draw more slowly, due to the increased number of points, but will show the waveform scrolling through the window. This is useful with low iprd values.
dispfft – display the Fourier Transform of an audio or control signal (asig or ksig) every iprd seconds using the Fast Fourier Transform method.
