The above image is from a drive from SB to p alt where I stopped at Denner to pick up a few bottles of wine and well, I had to sample and stare at the hills.

The upper frequency limit in humans (approximately 20 kHz) is due to limitations of the middle ear, which acts as a low-pass filter. Ultrasonic hearing can occur if ultrasound is fed directly into the skull bone and reaches the cochlea through bone conduction without passing through the middle ear.

some step sequenced filtered granulation on 2 cello samples

I am in the process of imagining how to make this a realtime application for a string piece. Even this long example of subtle variations on a 2 looped cello sounds, not more than 3 seconds each, is rather interesting. I am working out how I want to use this on a live signal and what to play with it. I sort of like some of the sounds and simply want to transcribe them, which may be the piece. I spent 3 hours listening to stuff like this yesterday, and really enjoyed it.

This is the room (studio E at CCRMA) where I spent Thursday making a piece in memory of Max Mathews who passed away at 84. It is an 8 channel piece that uses the smae technique heard in the above material, but on Max's stuff. (Daisy, Phasering Tensor Love, an interview and Max playing Chopin with the Radio Batton).

At the concert that I performed at CCRMA on Thursday evening (where I presented ToLEtFony) they played Numerology. I had not heard this piece before. I love it!!

This is an interesting collection of
