I noticed that .wav files are not exactly repoductible, event using the same command and the same song:

sidplayfp -w1-t10 Zoids.sid
sidplayfp -w2 -t10 Zoids.sid
diff 1.wav 2.wav
Binary files 1.wav and 2.wav differ

It seems that the 2 songs do not start exactly at the same offset.

Is this expected?

Thx

I tested this on
Sidplayfp V1.4.4, Libsidplayfp V1.8.8
and
Sidplayfp V2.0.1, Libsidplayfp V2.0.2

Yes, this is is expected due to the random power on delay. You can avoid this by passing the --delay=0 option.

Thank you for your anwer. I had seen the --delay option, but the online help does not make it clear that the default value is random, by default.
