CODEC Aliasing All Better Now

v0.13.10 CODEC upgrade is AWESOME !! The audio spectrum shown below is of an AM broadcast station playing music, with the Slice Receiver AM bandwith set to 16k. The DSP filter brick-wall is obvious at 8 kHz. I don't know what the roll-off at 12.5 kHz is. The -120 dBFS noise floor proves the Flex software gurus totally killed ALL of the aliasing noise. Amazing! No stinkin' R-C filters needed, just great software. John Stuart, KM6QX
