I just discovered spectrogram viewer on Audacity and my vocal sweeps inadvertently drew some violin arches and a content-looking long-haired chubby-faced girl with my voice (lower right)!
I love spectrograms! Half my lifetime ago, I would watch my favorite songs on the Winamp spectrogram for hours.
So I guess it should surprise no one that last week I had a wonderful time at Oberlin Acoustics Workshop this year, learning, hanging out and doing bridge rocking frequency taichi with brilliant minds and people I admire!
