Small updates on the PCM replayer documented here : http://www.msx.org/forumtopic7875p210.html

I tuned the filtering and re-sampling in my M file that does the conversion of the wav files to the phases data.
I fixed also some errors in the due to overflow in the integer representation of samples and added a small heuristic
able to improve the SNR when there is overflow.
 
I fixed the asm replayer in order to be sligthly more efficient.

No solution jet to the problem that affect the real SCC HW.
On emulators it sounds excellent, on the real thing just sufficient.

The results are in attach.

Use the SCC Flash Rom from Manulel Pasos or just an emulator.

Keys from 0 to 7 are active.

Comments from anyone willing to investigate the differences between the real thing and emulators are welcome.
