回應： The frequency of the signal output from the sound card

[dfaweew]

hello！i use simulate signal Generating a sine wave ;and Then read the file（The chart below）；We all know dt is the distance between data points，So I want to change the value of dt，so I think this can change the frequency of the output signal ，But when I put the signal output to the oscilloscope ，No matter how I change the dt value, but did not change the frequency output，I do not know why！！！Appreciate any help or tips，thanks！

Hi, dfaweew,

You can try to change the sampling rate of the sound format control, then you may get it by yourself.
