Laurie Spiegel plays Alles synth - temporary replacement Laurie Spiegel 2009-04-27 | This 1977 tape is one of the earliest examples of purely digital realtime audio synthesis. It manages to achieve an analog synth sounding quality, but it is entirely digital synthesis and signal processing.The interactive software I wrote and am playing in this video recycles my keyboard input into an accompaniment to my continued playing, which is why I called it a "concerto generator". I use part of one of the keyboards for control data entry, and the small switches upper right to access pre-entered numerical patterns. The sliders are mainly pre-Yamaha FM synthesis parameter controls, for the number of harmonics and amplitude and frequency of the FM modulator and carrier that constituted each musical voice.Until they restore the copy suffering from data corruption please look at this copy instead.Comments can continue to be left on the original's page where there have been many views and comments views, here:http://www.youtube.com/watch?v=K4T3eT56GlAThanks for watching,- Laurie
Laurie Spiegel playing guitar, shot Nov. 2012 by Dena Yago Laurie Spiegel 2012-12-13 | While Dena Yago was shooting some stills when interviewing me for her article, I picked up the guitar and started messing around, not realizing that Dana was videotaping. I realized that although I've played guitar most of my life there aren't any recordings or videos of me doing it so I figured I'd upload this brief one.
Spiegel Voyages Excerpt 1977 Laurie Spiegel 2012-12-06 | This is an excerpt of my late-1970s piece "Voyages", generated at Bell Labs using the "VAMPIRE" video-and-music co-generation system I had been working on as a varient of the GROOVE system that would output both visual and audible music. This particular clip lacks the audio track, so consider it to be one of the series of "Living Paintings" I had started doing using the same software. This was real-time algorithmic video generation, captured to a 3/4" U-Matic analog video tape deck. At the time, realtime algorithmic computer-generated visual material was something even Max Mathews didn't think the computer in that lab would be fast enough to do.For more info on my VAMPIRE system see my paper athttp://retiary.org/ls/writings/vampire.html
Spiegel VAMPIRE blue-start-run experiment mid-to-late 1970s Laurie Spiegel 2012-12-05 | This was just a short test-run of my mid-1970s "VAMPIRE" software that I wrote at Bell Labs. It was one of the very first "paint" programs. In this brief clip I was just testing out realtime generation of contrary motion and the avoidance of the cadence if the top and bottom curves had touched instead of turning back. No audio, just a visual excercise.This was real-time interactive video generation, captured to a 3/4" U-Matic analog video tape deck. At the time, realtime interactive computer-generated visual material was something even Max Mathews didn't think the computer in that lab would be fast enough to do.For more info on my VAMPIRE system see my paper athttp://retiary.org/ls/writings/vampire.html
Part 2: Laurie Spiegel Bell Labs Interview 1984 Laurie Spiegel 2008-07-15 | This interview was taped at Bell Labs in 1984, with brief intro by Max Mathews. Some of this footage may have made it into the documentary for which this was recorded but most of it has not been seen anywhere yet. Apologies for not knowing the name of the interviewer, and for the abrupt ending. This is the ending of the video I have of it. This is Part 2 of 2.

Remembering Home Laurie Spiegel 2007-08-19 | "Remembering Home" for electric banjo with digital signal processing was composed after returning to man-made New York City after a visit home to the wonderful ravines of northern Illinois, to a glimpse of a completely different life that might have been but was not, and to a family that will never again be what it was. http://retiary.org
Laurie Spiegel Playing 1977 Bell Labs Hal Alles Synth Laurie Spiegel 2007-01-26 | Concerto for Self-Accompanying Digital Synthesizer. The instrument is possibly the first realtime digital synthesizer, built at Bell Telephone Labs, NJ by Hal Alles and team, with C language software written by Laurie that processes the player's live input into an ongoing accompaniment that will continue to be played live against. This is a legal copy uploaded by the owner of the original tape. The OHM DVD's video was taken from this.
