Date: 11 Jul 84 23:08 PDT From: withgott.pa Subject: spectrogram looks To: islspeech^.pa After experimenting with the HALFTONE array, I found what to my eye looks like a better display of salient information in the spectrogram of Austin's voice. The GWIDTH is set to 5 for the following. This gives ample time to follow the transitions. The only changes are: I reset up to 143 to be 0 144 = 2 145 = 9 146 = 18 147 and on = 31. I would like to experiment with the display using a wider band pass. And can anyone also tell me how to try out resetting filter shape? Can this be done by changing values via INSPECT? --Meg Subject: SCALEDWINDOW.FPKG To:ISLSpeech^.pa cc: Halvorsen.pa SCALEDWINDOW.FPKG and DCOM should be useful for putting scales in scrollable and/or reshapeable windows. The most important function is SCALED.WINDOW.SETUP which takes the following arguments: a WINDOW, the maximum and minimum y-axis values, the offset for the x-axis from the bottom of the window (in points), the offset of the y-axis from the left side of the window (in points), the function which you use to plot your data in the window and a font descriptor for the font you want to use for the numbers on the scale. I'll try to write some documentation in the next few days, and also implement the grid drawing along the vertical axis (it now only supports the indication of 0-crossing, min and max value along the y-axis, while grid-points are indicated on the x-axis). Until I get some documentation written it may be useful to look at SCOPE.SETUP and SCOPE.PRINT on SCOPE.FPKG for an example of how to use this package. End of messagev TIMESROMAN óGACHAiz¸
