#X text 63 410 To use this patch \, connect your audio output back
to the audio input (channel 1 should suffice.) The latency measurement
assumes the feedback gain is at least about -14 dB - you can increase
the input sensitivity if need be.;
#X text 66 481 If you select "measure latency" a series of pulses are
timed using the "threshold~" object - note that it has an uncertainty
of 1.45 msec (at 44K1) \, so you might see the number jitter even if
the latency is constant.;
#X text 66 554 Select "test continuity' to see if there are interruptions
in the sound \, either at the input or output stage. If there are \,
the button will flash.;
