Finally got out and did a quick test using sas_77 program. Used my LMT MWS in .308 16" barrel, YHM Phantom SS .30 cal can, ZQI 7.62Nato ammo. On the sound side: GRAS 46BG mic/preamp combo, GRAS 12AL mic power supply, M-Audio M-Track 2X2M ADC. Calibrator is Larson Davis/PCB CAL-200, which supplies a 1khz tone at 114db.
Suppressed with Phantom SS:
Acceptable results with low-cost USB interfaces 192khz 24-bit ADC.
