No, it means the higher-frequency harmonic components of the square wave are attenuated, which affects how it sounds. Filtering a square wave in this way is particularly simple, but unlikely to be worth the effort. -- Jamie _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
