<p>Never thought of that, but that is really a cool idea. I was
finally able to get the libraries installed. I got it from the
yahoo ltspice group and it works, but of course it's not
automated. My problem was a path issue. Two paths were nearly
identical yet in totally different places and I didn't notice
that.</p>
<p>I really like the idea of using wav files as voltage sources. I
have a lot of baby steps to take first, but I'll get there in a
few weeks. Then you can have automated sweeps as if a person were
turning a pot.</p>

<p>Thank you all<br>

<div>and btw, next to param sweep, here's another cool
feature of LTspice:<br>
Using wav files as voltage source (or output, i.e. wav
dump of your circuit voltages - that need to be in +/- 1.0
volt range at the point of sending to wav, btw)</div>

<div> </div>
<div>So you could also "abuse" a wave file in place of a
potentiometer in some situations to get some more
elaborate bahavior of changing values than with the .STEP
command.</div>

<div>As I accidentally replied only to Mike, not SDIY
before, here the other mail for reference:</div>

So do you have a lib that does pots? I wonder how that
would work.<br>
It's been a while since I was adding stuff, do't recall
right now,</div>
<div>but:<br>
How about just sweeping resistor values? If it needs to be
a 3-terminal pot, sweep two resistors in a cross-fading
manner, I guess.<br>
</div>
<div>Here is en example that sweeps a capacitor value. With
the rsult that you get one curve for each step of the
sweep,</div>

<br>
You can either use a list with values for the sweep, but
IIRC you can also specify a linear or log or whatever
range and steps.<br>

<b>Betreff:</b> [sdiy] adding libraries to LTspice</div>
<div>I'm loosing my mind trying to add a potentiometer
library to LTspice.<br>
<br>
Some people say not to use pots, but I'm not sure that
would be a good<br>
thing either.<br>
<br>
Anyone have an easy procedure or any tips for adding
libraries?<br>
<br>
<br>
Thanks,<br>
<br>
Mike<br>
