<div>it's documented in 2.5.2 http://msp.ucsd.edu/Pd_documentation/x2.htm and 3.1 http://msp.ucsd.edu/Pd_documentation/x3.htm of the Pd documentation, but I don't know who actually reads it...</div>
<div> </div>
<div>BTW, the manual could need an update. For example, the section about dollarsymbols is outdated:</div>
<div> </div>
<div>> Note that the expansion of variables such as $0 and $1 only works at the beginning of the symbol; so, for instance, "rats-$1" will not be expanded.</div>
<div> </div>
<div>And the section "Audio in Microsoft Windows" talks about Win95/98 :-)<br/>

<div>Is this in the Pd Manual somewhere? Could be a good point to add to future questions.

Rough explanation: Pd sets up two FIFOs, one for audio input and one for<span class="Apple-converted-space"> </span><br/>
output, and "delay" sets the length of those FIFOs. I/O is managed so that<span class="Apple-converted-space"> </span><br/>
(in theory at least) the sum of the number of sample frames in the input<span class="Apple-converted-space"> </span><br/>
and the output FIFOs add up to the "delay", plus or minus one 64-saple block.<span class="Apple-converted-space"> </span><br/>
<br/>
So theoretically at least, the total delay from audio input to output should<span class="Apple-converted-space"> </span><br/>
be the sum of three things: this number, the OS's internal audio latency<span class="Apple-converted-space"> </span><br/>
(which depends on all sorts of factors) and the A/D/A devices.<span class="Apple-converted-space"> </span><br/>
