I’m doing this for my senior project in school, so I will be releasing new updates to this program weekly. The premise of this program is that it is a DMC converter that has a UI and several options. It has no name yet
Description-
Converts a PCM .wav (16 or 8-bit, stereo or mono) to DMC format. Only waves above 33144hz will work properly–others will play too fast. If you have a 22khz wave you want to play, convert it to 44khz (or if possible, 33144hz) in some other program first. My program converts the sample rate for larger-than-33144 rates but it does a dirty job of it, so the cleanest sound will probably result from you putting it at 33144.
You can also convert a PCM .wav to another PCM .wav approximation of the DPCM. This is useful for people who make .it/xm/s3m files and want to have dpcm samples that sound like a NES’s would. You can also just load full songs into this to play around (warning, large filesizes take awhile).
Compressed .wav formats are not supported, and they will not be in the future most likely. This includes ADPCM, uLaw, etc.
Future features:
-<33144hz conversion
-multiple quality/pitch settings
-Graphical DMC wave display (directly editable, copy/cut/paste)
-Preview for the current DMC wav at given frequency
-The ability to chop up large wav files so they can be played back as DMCs on the NES
-Drag ‘n Drop functionality
-additional filters
-bit crushing
