Ok, back to it. Currently working at a version that saves 4 bytes in the stack (it's the 10th release candidate...).
The optimization quest is a never ending one. :D

After this, unless another new idea springs to mind, I'll release it and leave it to others to find if anything can be optimized ;)
I cannot wait and am already getting in pouncing position. :p

(Last time I promised a release, I got my computer stolen, got a bit sick afterwards, went to holidays, had to deal with damages at my home while on holidays, and later spent much more time than expected working at a Christmas gift... Hoping I can stay focused this time :D)
Argh. The real life quest is also a tough one. Be brave adventurer!

Getting closer. Latest (last?) tests seem OK.
Writing doc.

The following table describes roughly-but-in-detail how the WAV file is build, and the corresponding code.

Ok, yesterday my home was without power, so work is a bit slow.
So, another teaser ;)

(This scheme doesn't take a few details into consideration, that may affect the values a little, such as: standard speed bytes always mix 0 and 1due to parity or start/stop bits, and so on.)
