TimeLagAccumulator Patch A replica of the San Francisco Tape Music Center "Time Lag Accumulator"
A replica of the San Francisco Tape Music Center "Time Lag Accumulator," hereafter referred to as TLA, because of the inherent joke, and because of impending repetitive stress issues. The TLA was originally a long tape delay scheme used by Terry Riley, Pauline Oliveros and others at the San Francisco Tape Music Center. It involved a couple of well calibrated tape recorders, one to record onto, and the other placed some distance away for playback. This same basic scheme was later utilized by Fripp & Eno, and forms the basis of "Frippertronics."
tl.crossover4~ External 4th order Linkwitz-Riley crossover filter (high and low).
This is a commonly used high-end crossover filter for loudspeakers. It is a 24 dB per octave crossover filter with each filter down 6 dB at crossover. An important feature of the filter is that the two drivers (the low and high passed filters) are actually in phase at all frequencies. That is, even though the filters have their own characteristic phase responses the phase difference between the two output signals is the same at all frequencies. As a result, each filter section has the same group delay.
tl.n++ Abstraction Slow uppward uzi for large tasks.
Max is responsive while task is performing, as each count value is delayed by 0 and defered.
tl.n-- Abstraction Slow downward uzi for large tasks.
Max is responsive while task is performing, as each count value is delayed by 0 and defered.
tm.delay Abstraction Modified delay that delays messages and stops the delay when it receives and allstop bang.
v.delay External v.delay delays the incoming stream by a number of frames
v.delay delays the incoming stream by a number of frames, You can freely vary the number of frames up to the maximum defined in the argument in the object box.
v.track External v.track follows a specified small object across the video field with sub-pixel accuracy and no delay.
v.track follows a specified small object across the video field with sub-pixel accuracy and no delay. Objects are tracked best against a contrasting solid background, and will be lost if they travel faster than 8 pixels per frame. You can also tell v.track to track an unmoving part of the screen, and move the camera (instant steadicam) (Again, if the camera moves such that the image moves more than 8 pixel per frame, you will lose tracking.) If you supply a profile stream (i.e. from v.silhouette’s second outlet), v.track uses the silhouette to define a mask that will cause areas showing no silhouette presence to be ignored in the tracking process, which improves tracking across complicated backgrounds. v.track is best understood by looking at the v.track examples, because it works best when supplied with properly pre-processed streams.
vb.delayA~ External a fractional delay line using first-order allpass interpolation and feedback.
vdel~ External a variable delay unit with feedback
a variable delay unit with feedback. It is controlled by an internal oscillator. However a signal connected to the fifth inlet will override the oscillator. The values of this input should range between 0-1.
vd~ External variable delay tap
xj.revdel1~ Abstraction simple delay element
