Guide part 5 - low-pass filter
Posted: Sat Oct 08, 2016 1:32 pm
I just completed part 5 of the guides including wiring things up to test the audio. The audio works, but coming out of the speaker, it is very quiet. I can hear it, but just barely. Does this indicate that there is something wrong with my filter? When I plug headphones in, the sound is much louder, but there is a lot of noise; I am new to emulators and all of this, so this might be normal. I haven't gotten to the part where I add a volume wheel, but that will just make it quieter, since it is adding resistance. Is all this normal? If not, what can I do to troubleshoot? Is there a way I can test my low-pass filter with a multimeter or something? I used a 10nF capacitor from the original Gameboy controller board rather than a 33nF, if that makes a difference (the guide says 10nF is fine).
Thanks!
Thanks!
