delay~

The delay attribute (the delay time) of a delay~ object can be specified with tempo-relative timing (such as ‘notevalues’) instead of samples. This example shows a delay time of a dotted eighth note rhythmic value, at whatever the current transport tempo is. The transport tempo is 120 bpm by default; a dotted eighth note at that tempo will last 375 ms which, at a sample rate of 44100 samples per second, is 16,537.5 samples.

The delay~ object creates a "ring buffer" into which it constantly records the signal coming in its left inlet. The first typed-in argument specifies the size of the buffer, in samples. The second argument (or a number in the right inlet) specifies how many samples in the past delay~ should look for the signal it will send out its outlet.
