   More looning around this morning. This time I'm trying to build a crude model around the "cry" of the loon. (Recording: reference, synthesized (wet), synthesized (dry))
   The pitch curve of the cry is both jumping and rising. The jumps (which sound like voice cracks) remind me of yodeling.
   Since my loon call yesterday, I've added a bit more grit to the sine oscillator spectrum. I've also added a bit of ambience noise using filtered white noise and sparse noise for pops.

     I've attempted to build an empirical model of the classic loon warble. It's just made from well tuned sine waves and envelope generators.

     The first is the actual call I was analyzing. The second is my synthesized attempt. The third is my attempt put through a forest reverb impulse response.

     There's a beautiful lilt happening in that initial onset that I'm missing from mine. But, I think it captures the vibe well enough.

     Today's sound fixation is this canadian loon call:
