SOLVED BY ADJUSTING ATTACK TIMING.
I intend to replicate the sound of a simple clock's chime. So far, using LTSpice, I managed to control attack and decay times.
Please check the sound in the attached .wav file. I understand that kind of a thump is perceived at the start, which I find annoying and far fom nice.
The signal, taken at the output after several DC blocking caps looks as shown. Really.
My questions:
1) Do you agree on the initial anomaly? My hearing is definitely bad so I do not trust much on what I perceive.
2) If so, is it an artifact created by LTSpice when sampling the signal and passed into the .wav file?
3) Or is it that initial jump of around 300 mV pk-pk, the reason of it?
4) Or just my sound card?
Comments appreciated.
