|I'm using assembly, XE SYSTEM (65K bytes).  I'm trying to create

|Channel 2 as a high pass filter to pass only 800 hertz. Possible?
 
 
        It depends on the waveform of the sound. You would need something
like a tank circuit. This will cut out frequencies above and below the critical
out. Also, depending on the harmonics and waveforms and such, a method like
that can be very inneficient.
