TMA block: The "TIME" parameter

Hi,

The "TIME" parameter in the TMA block can be set from 0.1 up to 10., default is 2.5

Does this translate to seconds? If not, how is the relative scale?

At 2.5 does the TMA block choose 2.5 seconds of the reference signal only?

If I have a reference signal with the length of 8 seconds should I set the time parameter to 8.0?

Thanks for your help!
 
AFAIK, it is the amount of time (in seconds) over which the input signal is averaged.

So your question about 8.0 = 8 seconds, yes.

Again, that is as I understand it.
 
Hi Scott, thx for your reply!

That's what I guessed but 2.5 seconds as default seems a bit short to me, so it's not really much use to play in different octaves and positions etc.
 
It's the time constant of the averaging filter. It's the amount of time for a result to decay to 37% of its initial value.
 
The manual says:

Duration: By default, the capture process averages about a ten second
window. For more or less time, increase or decrease Average Time on
the PROCESS page of the Tone Match edit menu. The “capture window”
is roughly 4-5x this value in seconds—plenty for Tone Match to “hear”
all it needs. If the frequency plot “falls flat” before you press stop, you
have the window set too small. Setting to max invokes a “peak hold”
mode where the maximum is used rather than the average.
