Smaart 7 Multi Time Window

I am curious about the performance of the new 'Multi Time Window' in Smaart 7. Constructed out of several simultaneous FFTs to 1/48 8ve or better above 60Hz.

Noise has been looped back into the computer, so we are looking at a measurement that has no speakers or microphones, infact the only differences between the two channels should be those in the electrical input circuits of the PreSonus Firebox, ie not much.

I have just progessively added delay to the reference, so the measurement signal is seen to be arriving early. The demo is limited 50ms of delay, so we stop there.

The three windows from top to bottom are the Live IR, Phase, and Mag. The value in the centre of the Live IR, tells you delay currently applied.

Traces have been measured with 16 Averages, with the Complex average method, Coherance blanking is at 20%, no smoothing.

The coherance traces seems to show clearly where the breakpoints between different FFTs are.
