1.
这程序我有,
很久以前测试过,
刚又在 Windows 7 X64 上测试,
它只透过声卡发出声音,
并不会透过蜂鸣器(Buzzer)发出声音.
2.
至于率音调对照表,
那只是小数四舍五入,
人的耳朵听不出来,
整数也减少打字错误.
PS 文档说明 :
-- Notes --
Not all modern PCs have an internal PC speaker. Some
may use an integrated sound card instead. Some are just
silent. Windows 7 seems to have removed this hardware
feature all together for some unknown reason :-(
所以 应该是 Windows 7/8/8.1/10/11 都不适用,
至于 Windows XP/Vista 没测不知道.
