This parameter only helps if the causes of the faults are greater variations in DC voltage, not dropouts.
This is the case when the waves are only visible above or below the midline. DC is less of a problem for the PC-1500/1600 / E / G series. Otherwise, the behavior can also worsen. In other words, sometimes the parameter helps, sometimes it does not, and sometimes it is wrong. Unfortunately it only helps to try out.
With the PC-12/13 / 14xx series, this parameter improves the read-in more often.

As far as I understand you, it would be an advantage if the sample frequency of Bin2wav by default would be 44.1 (48) kHz.
I still got hints from the music scene today from the boys who are constantly making music with all sorts of old computers.

I was advised not to make any changes to the code, because there is only a real advantage if the sample rate matches the internal clock frequency of the sound card (mostly 48 kHz). This frequency would have to be queried across platforms, implemented in Bin2wav and then on another computer, the advantage might no longer exist. Mostly it would only be conflicts of individual drivers with certain platforms.
For problem cases the options -l2 and -l1, (for SuperTape also -l3) are available, which can now be set centrally in the SHARPset for Windows.
