I've implemented a faster FM demodulator for rlt_fm.
Let me see if I can get a fixed-point version written.
I've cleaned it up and it is in my repo. You can enable it with "-A ale" https://github.com/keenerd/rtl-sdr/commit/025fb56dff98 Some quick benchmarks: std: 10% fast: 7% lut: 7% ale: 7% Sound quality is also noticably worse with ale, but that might be from an error in the fixed point conversion. How does the math look to you? -Kyle http://kmkeen.com
