delay~

Delay line specified in samples or Max tempo-relative time format

Description

delay~ delays a signal by a certain amount of time. This object uses the Max time format syntax; delay times can be either samples (determined by the sampling rate) or tempo-relative values.
The differences between delay~ and tapin~ / tapout~ are as follows: First, delay times with delay~ are specified in terms of samples rather than milliseconds, so they will change duration if the sampling rate changes. Second, the delay~ object can reliably delay a signal a number of samples that is less than a vector size. Finally, unlike tapin~ and tapout~, you cannot feed the output of delay~ back to its input. If you wish to use feedback with short delays, consider using the comb~ object.

Arguments

Name Type Opt Description
maximum-delay-memory (samples (int)) and initial-delay-time (samples (int)) list opt The first argument sets the maximum delay in samples. This determines the amount of memory allocated for the delay line (the default value is 512 samples). The second argument sets the initial delay time. The default value is 0 (samples). The time interval can be either a number which specifies time in milliseconds (e.g. delay~ 44100 200) or a notevalue (e.g. delay~ 2000 2n).

Note: While the delay~ object lets you specify time in any of Max's standard time formats, the interval attribute argument should be used when specifying time in any other time unit besides milliseconds or notevalues (e.g. delay 22050 @interval 11025 samples).

If notevalue, ticks, or bars.beats.units are specified for the delay interval, the object will not operate unless the transport is running.

Messages

int delay-time (samples) [int]
In right inlet: The delay time in samples. The delay time cannot be less than 0 (no delay) nor can it be greater than the maximum delay time set by the argument to delay~.
float delay-time (samples) [float]
Converted to int.
list time/transport-settings [list]
Performs the same function as anything.
anything time/transport-settings [list]
In right inlet: A list may be used to specify time in one of the Max time formats.
clear Clears the object's sample memory.
maxsize maximum-delay-memory (samples) [int]
The word maxsize followed by a number designates that number as the amount of memory allocated for the delay line (in samples). The default value is 512.
ramp ramp-time (milliseconds) [float]
Sets the time, in milliseconds, taken to ramp to a new delay time.
signal In left inlet: The signal to be delayed.

Attributes

Name Type g/s Description
delay atom Sets the delay time for the object. Delay time can be specified in any of the time formats used in Max.
