upped the time steps to 30 seconds each, includes .wav, .asc

Originally posted by jcx
the zip should contain a 2 channel 16 bit 44.1K .wav

1st second 1 KHz -3 dB, no added distortion

left channel 3rd harmonic
1% 1-2sec,
2% 2-3sec,
3% 3-4sec,
4% 4-5sec,
5% 5-6sec;

right channel 1% distortion component
2 KHz 1-2sec,
3 KHz 2-3sec,
4 KHz 3-4sec,
5 KHz 4-5sec,
6 KHz 5-6sec;

runs better than 1/2 real time on my machine, big delays also when LtSpice tries to load data into waveform viewer

SwCad could be run in batch mode to skip waveform viewer

@192K zip was too big, used 7zip ( 31M wav=>24K .7z, not bad but you could say that the 31M is "encoded" in the 2K .asc file, just takes a little longer to extract )

and of course, diyAudio doesn't recognize .7z, so rename without .txt and open with 7zip

rt clik on filename and a dialog should open, select Rename

or select file (left clik filename or icon) and use <File> tool bar to get to Rename cmd, left clik 2nd time (wait some time not double clik) directly enters Rename mode

then you are able to edit the file name, left clik inside brackets containing the highlighted filename to get ordinary cursor with normal line edit behavior, <cr> or cliking outside brackets ends edit

ignore the warning/ clik OK/Yes when when you finish

Location: Munich it now, problem was file extensions were not shown...

Thanks, nice files, give also good idea how sounds -40db of K2 to K6.

It shows 0,035% for the clean wave and 1,001% for K2, dropping to 0.99% for K6.

I increased sampling points x4 and it dropped down to 0,015% for the clean wave.
Still much 2 much, maybe more averaging could help.
Don't know how good was the guy who wrote the program, I understand maybe 50%.
