<h3>Functions</h3>
|
||
|
|
<p class=func><span class=keyword>delay</span>(channel, milliseconds);</p>
|
||
|
|
<p class=desc>Set output channel (0 to 7) to delay the signals by
|
||
|
|
milliseconds. The maximum delay is approx 425 ms. The actual delay
|
||
|
|
is rounded to the nearest sample. Each channel can be configured for
|
||
|
|
any delay. There is no requirement to configure the "taps" in increasing
|
||
|
|
delay order.
|
||
|
|
</p>
|
||
|
|
<p class=func><span class=keyword>disable</span>(channel);</p>
|
||
|
|
<p class=desc>Disable a channel. The output of this channel becomes
|
||
|
|
silent. If this channel is the longest delay, memory usage is
|
||
|
|
automatically reduced to accomodate only the remaining channels used.
|

<h3>Notes</h3>
|
||
|
|
<p>Memory for the delayed signal is take from the memory pool allocated by
|
||
|
|
<a href="http://www.pjrc.com/teensy/td_libs_AudioConnection.html" target="_blank">AudioMemory()</a>.
|
||
|
|
Each block allows about 3 milliseconds of delay, so AudioMemory
|
||
|
|
should be increased to allow for the longest delay tap.
