Generate Impulses for a List of Audio Values (multichannel) The what~ object generates an impulse -- a signal value of 1 for one sample -- when its input signal crosses a value threshold. The object accepts a list of threshold values and will generate impulses for all of them. Connect a phasor~ to what~ to create a repeating rhythm. For example, when sending in a list of 0 0.25 0.5 and 0.75, what~ will output an impulse four times for each phasor~ ramp. Cycling '74 MSP Input A signal containing or ramping through values you want to detect TEXT_HERE Impulse if Values Detect, 0 Otherwise what outputs 0 until it detects a matching value in its input, then it outputs 1 for one sample. Index of Matched Item TEXT_HERE One or more values to detect If one or more values are arguments to what~ they define the initial list of values. Define a single value An int sets a single value to detect, replacing any existing values. Define a single value An float sets a single value to detect, replacing any existing values. Define values to detect list sets the new values to detect, replacing any existing values. A list message is alternative to setting the matches attribute. If syncupdate is enabled, the new values are not used until the input phasor resets. Clear list of values The clear message removes all values that have been added to the what~ object. If syncupdate is enabled, the values are not cleared until the input phasor resets. Input Signal The input signal used for theshold analysis, usually a phasor, though any signal can be used. List of Values to Detect Sets the values to detect Sync Value Changes When syncupdate is enabled, messages to change the values to detect do not take effect until the input phasor resets. A reset is defined as a direction reversal in the signal. Trigger Mode Determines how what~ matches values in the signal input. Detect value in an ascending ramp The previous sample must be less than or equal to the target and the current sample must be greater than the target. Detect value in an descending ramp The previous sample must be greater than or equal to the target and the current sample must be less than the target. Detect value in an asecending or descending ramp The value is detected if either the ascending or descending condition is true. This mode is useful for detecting ramps in phasors with either positive and negative frequencies. Detect exact value The value is detected if it is exactly equal to the current sample. This mode is not recommend for phasor ramps since it is unlikely the ramp will output a sample exactly equal to any particular value. The what~ object is sample-accurate when Scheduler in Audio Interrupt is enabled. More details here.
