Hi,
Can anyone point me to a simple code example for how to
determine the phase at a specific time in a waveform?
ex. if I have a sample that is 5 seconds long and want to
know the phase at 2.5 seconds
I'm open to code in any language or a scripted example if
such a tool exists. If there is an ui which has that
feature I am also interested.
Do you mean... for a very simple sine wave?
Assuming yes:
p = asin( x / A )
Where:
A is the amplitude of the sine wave
x is the value of the sample (-A <= x <= A)
p is the phase of the wave in radians (-pi/2 <= p <= pi/2)
If not this... then... "what Jörn said!" :-)
