Filter a signal logarithmically (multichannel) Use the slide~ object for envelope following and lowpass filtering. Cycling '74 MSP MSP Filters (signal) Input TEXT_HERE Slide up TEXT_HERE Slide down TEXT_HERE (signal) Output TEXT_HERE Slide up value Specifies the slide up value. The default is 1. (Also accepts integers for these arguments as well as the associated messages which address these parameter settings.) Slide down value A second argument specifies the slide down value. The default is 1. (Also accepts integers for these arguments as well as the associated messages which address these parameter settings.) Set the slide up/down value In middle inlet: Use an int to set the slide-up value.

In right inlet: Use an int to set the slide-down value. Set the slide up/down value In middle inlet: Use a float to set the slide-up value.

In right inlet: Use a float to set the slide-down value. Set the current output sample value to 0 Sets the current output sample value to 0 (the next incoming value will smoothly transition from that 0). Signal to be filtered In left inlet: A signal to be filtered. Whenever a new value is received, slide~ filters the input signal logarithmically between changes in signal value using the formula:

y (n) = y (n-1) + ((x (n) - y (n-1))/slide)

A given sample output from slide~ is equal to the last sample's value plus the difference between the last sample's value and the input divided by the slide value. Given a slide value of 1, the output will therefore always equal the input. Given a slide value of 10, the output will only change 1/10th as quickly as the input. This can be particularly useful for lowpass filtering or envelope following.

In middle inlet: Use a signal to set the slide-up value.

In right inlet: Use a signal to set the slide-down value. Set the slide down value The slidedown attribute specifies the slide-down value to be used when an incoming value is less than the current value. Set the slide up value The slideup attribute specifies the slide-up value to be used when an incoming value is greater than the current value. The slide~ object filters an input signal logarithmically between changes in signal value. The formula is y (n) = y (n-1) + ((x (n) - y (n-1))/slide). The filtered signal.
