Hello

I just applied your patch to the main source tree. Thanks again for it.

Just a small question regarding :

+	/* Anti-alias filter is not required when nAudioFrequency == 50066 Hz */
+	if (nAudioFrequency>50000 && nAudioFrequency<50100)

Why don't you just use 	"if (nAudioFrequency==50066)" ?
