Hello Eric, all,

arecord -c 1 -r 12000 -f S16_LE capture.wav
sox capture.wav capture_tmp.wav speed 2.0
jt9 -9 -d 3 -S 300 capture_tmp.wav
cat decoded.txt

That is amost exactly what I am doing in SlowJT9, just in a more = fancy (user friendly) way ;-)
Does the speeding-up includes averaging ?

Paul, et.al.

Correct, the original timings were fit into a "window" vs. simple=
scaling.  Since the slowJT exe wouldn't run in WINE, I just ran a few =
commands to decode K5DNL:

arecord -c 1 -r 12000 -f S16_LE capture.wav
sox capture.wav capture_tmp.wav speed 2.0
jt9 -9 -d 3 -S 300 capture_tmp.wav
cat decoded.txt

decoded.txt:
0000   1  -26   0.1   2400.   = 1   VVV DE K5DNL        &= nbsp;  JT9

jt9 is the standard executable decoder from WSJTX v1.9.1.
