Just one simple question : why 7200 samples/sec ? It is not a standard sound card sampling rate. Is there a specific reason for this sampling speed ? Perhaps Bill was using an external A/D converter. For the technique to become widespread and accepted by many (all), it shouldn't rely on an ad-hoc hardware. Modern sound cards have superb A/D converters, so why not use them ? 73, Alberto I2PHD
