More wav-stuff

This time 4 bit at 4000 Hz for chiptune-like music with low file size needed! I also added a title screen so that you know when the app is still running (you won’t see or hear anything if it crashed).

I am considering RLE compression as an option for even smaller file size.

Wave samples on Pokemon Mini

Sunday, December 18th, 2005 at 23:15

I used the Pulse-Width-Modulator of the PMs sound generator to play real wave samples. By changing the duty of the output wave it is possible to “emulate” an analog sound signal. The output sounds quite good, but the PM is not loud enough so it’s a good idea to hold your PM close while testing these ROMs.

I noticed that 8 bit samples sound more awfull then 6 bit samples, in this version you can use the B button to decrease the bit-width of the samples down to 5 bit (i think 6 bit sounds best) and the A button to increase it again (up to 8 bit of course). This problem probably occours because the lower the bit-width of each sample the higher the PWM units frequency (which in turn results in a better signal quality).

Here’s the link to the sample binaries and source.

Starting with C#

This is a simple chat application which allows you to start a server and connect to other servers by IP address. It is called “PaddleNet” because it might be the start for a Pong online network where you can start games with up to 4 players and have chat rooms ;)

Anyways, if you want to test it then get someone who just has a totally sad and lackadaisical day like you and click on “Start server”. Then instruct your mate to connect to the server by clicking on the “Connect” button after he entered your IP address which should by default appear in the top left text box on your PC.
