Claus PM'd me about using this to clean up audio recordings. This is possible, but MEMU will probably auto-run the game and so the problem will be breaking into it to save the file (The same problem as real hardware).
A beeter solution is some dedicated software to apply the cleaning directly, read in the original file and produce a cleaned copy. The copy can then be tested in MEMU to validate it.
I can think of a number of levels of cleaning:
* A simple "squaring" function, with hysteresis to prevent jitter at the edges.
* As above but with a timing filter to adjust the time between edges to be the "ideal" value for a zero or one.
* A two stage conversion WAV->MTX and then MTX->WAV. This process could probably include some higher level checking of the data format. Correct number of bits, correct chunk length etc.
I think I am talking myself into some work here
A couple of ways this could be implemented:
* In C or C++ with a command line UI. I would develop on Linux but there should not be any problem for people to compile on Windows.
* In Python. Execution would be slower, but a simple cross platform GUI would be possible.
Comments?
