LTSpice - chime's ding simulation - solved

[atferrari]

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.
