lookup~
| External |
   |
Use a buffer~ for nonlinear distortion of a signal
Use a buffer~ for nonlinear distortion of a signal. lookup~ allows you to use a table of samples (buffer~ object) to do waveshaping on a signal, in which the Y values of a input signal are used as X values to look up new signal values. Input values of -1 to +1 are mapped to table values between 0 (or the specified sample offset) and the size of the table. |
|
loop-sf~
| Abstraction |
 |
Loops a selected mono sndfile. |
|
lores~
| External |
|
Low-pass filter with resonance.
Low-pass filter with resonance. lores~ implements a cheap lowpass with an adjustment that lets you add the resonance you've been looking for. The middle inlet sets a kind of cutoff frequency, but the sharpness of the filter depends on the resonance. 0 is a little bit sharp and 1 as sharp as you're going to get. |

Spectral or Time-domain Energy |
|
lp.c2p~
| External |
|
Convert Cartesian to Polar coordinates
This object was developed prior to the availability of the cartopol~ object in MSP version 2. It is retained in the Litter Power package to allow older Patchers that required this object to run unaltered and for users of older MSP versions. Conveniently, the interfaces of lp.c2p~ and cartopol~ are identical. |
|
lp.frim~
| External |
|
Frequency domain interval mutation
The Frequency-domain Interval Mutator is a variant of the Time-domain Interval Mutator (lp.tim~) object, modified in two ways to better handle frequency-domain signals (for instance, signals produced by the fft~ object). |
|
lp.frrr~
| External |
|
Low-frequency noise
Low-frequency noise is generated from a sequence of random values chosen at a constant rate slower than the sampling rate. In its simplest form, it functions as a noise generator passed through a sample-and-hold module. However, lp.frrr~ also allows the samples between the randomly generated values to be interpolated, either linearly or quadratically. |
|
lp.grl~
| External |
|
Phase unwrapping
This is a utility object, designed primarily for calculating the phase unwrapping typically performed as part of the Fourier Transform in spectral analysis. It could, conceivably, be used for other purposes. |
|
lp.grrr
| External |
|
"Gray" noise (Control domain)
This is a control-domain version of the lp.grrr~ signal generator. |
|
lp.grrr~
| External |
|
"Gray" noise (Signal)
Gray noise results from flipping random bits of an integer representation of the sample signal on a sample-to-sample basis. The spectrum is stronger towards lower frequencies. |
|
lp.lll~
| External |
|
Parametric linear congruence "noise"
"White" noise using the Linear Congruence algorithm, while allowing you to specify values for the LC parameters. See lp.lili for more information on parametric linear congruence. The lp.lll~ object works very much like lp.lili, except that the integral values produced are scaled to the range -1 < x. < 1 for signals. Note that the scaling factor is calculated relative to the mod parameter, so the maximum power range is always produced (except for LC cycles that get stuck at a constant… this can happen!). For many parameter combinations, this cycle of numbers generated may be very short. In other words, the result may be much closer to pitch than noise. There are many intermediate signals. |

lp.p2c~
| External |
|
Convert polar to Cartesian coordinates |
|
lp.pfff~
| External |
|
Brownian " (1/f2) noise |
|
lp.phhh~
| External |
|
"Blace" (1/f3) noise
Black noise is fractal noise that is even "darker" than Brownian nosie. It is characterized by a falloff of about 18 dB per octave. |
|
lp.ppp~
| External |
|
Popcorn (dust) noise
This noise generator, known variously as popcorn or dust noise, generates exponentially distributed pulses of varying amplitude and pulse width. It resembles kinds of noise frequently found in telecommunications lines and sometimes in radio broadcast. Curiously, in most naturally occurring circumstances, the pulses are all of the same sign, either positive or negative. The lp.ppp~ object supports both, as well as a symmetrical variant in which positive and negative pulses are mixed at random. When the density of pops becomes high and pulse width also increases, it becomes possible for pops to overlap. The current implementation makes no provision for overlapping pops; one pop must be completed (i.e., the signal must return to 0) before the next one can begin. Thus, the actual frequency of pops may fall slightly underneath the specified mean. |
