Hey everyone,
I’ve made a small update to the MAP again. This time:
* Added information to the PSG samples article about the fact that the
PSG output volume has a logarithmic scale. Thanks go to Arturo Ragozini
for pointing this out.
This is pretty important information if you want to replay samples on
the PSG :). It is also quite unfortunate, because a lot of resolution is
lost (if there’s much amplitude, one doesn’t benefit much from being
able to have more details in the low amplitude ranges). I’m guessing
that a 4-bit sample played on the PSG is in fact pretty much comparable
to a 3- or 2-bits one replayed on a common linear DAC.
Another update:
I have now also included information on how to play 8-bit samples on
your PSG.
Many thanks again to Arturo Ragozini, it is pretty impressive stuff :).
Note however that all of this is theoretical, and hasn’t actually been
tried out ^_^. It should work, but if you encounter any problems or have
comments, feel free to send me an email.
