    Default Oscilloscope trace sound wave ilda?

    As above..

    Just starting some research on this..

    A client needs this to be displayed as part of a logo...

    I know pangolin has the win amp plug in.. Just about to have a look to see if I can export to ILDA..

    Cheers

    Can you code? If so, here is a suggestion:

    1) Convert one channel of the wav file to amplutide vs time points.
    2) Break it up into pieces equal to frame rate.
    3) Use FFT to generate frequency response
    4) Plot each freq response snippet and save as an ILDA frame.

    Probably harder than it sounds but I think it would work, more or less.

    What about Lissajous command. I don't know if it's built into Pangolin but I have it on my LGgraph DSP. It has 4 generators per axel. It does exactly what you are looking for. But it can't be converted to ILDA.

    If you're looking for something like the ZoofScope output, I could give a try saving a few of those frames to Ilda format.
    You only need the oscilloscope right? not the spectrum..

    dave, if you can pause the winamp on the "note" or wave you want, then open LD2000, it will be in the "buffer" for LD and you can save that as a file...
