How to calculate the Factional Delay sending data ?

Hi, all

today found some pieces in EngineerZone, it's really helpful....

about the Theory:

j.L. Says: when fs = 48 kHz, T is 20.8 microseconds.

so i figured out the above Questions 1./2./3. this picture is the equation print out:

and it is matched the sigmastudio output capture.

Now, just this Question, the "Signal Invert" cell , when sending data, have click noise, any ideas ?

already use the safe write, should i operate like this: mute --> set invert --> unmute ?

i had try mute --> wait some time --> set invert --> wait some time ---> unmute.

it's still have 'Click" noise,

Hi Sojourney,

I'm glad you were able to answer most of the questions on your own.

Inverting the signal at a random point in time will create a discontinuity in the signal as it "jumps" from one value to another. This will almost always create a "click" sound because of the sudden jump in the signal, which manifests itself as high frequency noise on the output.

The only way to avoid this click sound is to do a slow fade, using slew. Use an "external control slew volume control" to do this. https://wiki.analog.com/resources/tools-software/sigmastudio/toolbox/volumecontrols/singleslewextvol

Connect a "DC Input Entry" cell to the red input pin. For non-inverted operation, use a value of 1 in the DC cell. To invert, enter a value of -1. This should avoid the click sound, but it uses many more instructions.

Hi Brett,

thanks for your help.

yes, it should be works. but the project is 4 channels, no enough space now, ok, i will try to reduce some items in project and do the "slew phase"
