sound system setup

Description

..this is made for live-sound-engineers,

it's an RTA and a DELAY-FINDER.

DELAY-FINDER:

the delay-finder can find the inherent delay of any system,

including your soundcard by sending an impulse and measuring the time until the response arrives.

it's not too accurate, about 2 ms jitter or so.

to get more accuracy, use the built-in phase scope.

workflow:

-check the system by clicking the big button on the left.

-hit the small 'take from response' - button to set the system latency.

-enable 'align' left of the oscilloscope.

-lower the numbers at 'system latency correction' SLOWLY until the oscilloscope shows an ascending, straight line.

RTA:

sports two curves with customizable colors and variable averaging.

besides,the is a 'capture' function that captures the second (slower) curve.

if you press 'inv' , the captured curve will be inverted,which is great for

tuning the EQ of your system without having to send pink noise all over the place for ages.
