I wrote a c program which creates a wave file with a 1khz sine.
It looks ok in Audacity but when I switch to the spectrogram I can see that there are many other frequencies too…
I attached the wave file.
If I use Audacity’s generate function and I generate a 1khz sine with 10 secs and 1 as amplitude it looks the same in the waveform view. The only difference is in the spectrogram.
But why is there a difference?
Does Audacity show all points in the waveformview if I zoom in?
I appreciate any help.
