Added:

Wave In has now buffer mode, which acts like times per second for peak
mode, but instead of delaying, it still reads the value 10 times per
second and takes the averages. This is usefull with mechanical
keyboards, which makes short loud noises hence a lower average is the
result (this may vary per mic)!

Bug fixes:
none

Worth mentioning:
Settings file has a new parameter, hence old settings files aren't
recognized anymore. You can simply copy your old setting to the new file
(Settingsv1_4.ini), but leave the buffer = 1; at the end!
