ATEST(1)		    General Commands Manual		      ATEST(1)

NAME
       atest - Decode AX.25 frames from	an audio file.

SYNOPSIS
       atest [ options ] wav-file-in

	      wav-file-in is a WAV format audio	file.

DESCRIPTION
       atest  is  a  test application which decodes AX.25 frames from an audio
       recording.  This	provides an easy way to	test Dire Wolf	decoding  per-
       formance	much quicker than normal real-time.

OPTIONS
       -B n   Bits  /  second  for data.  Proper modem selected	for 300, 1200,
	      9600.  300 baud uses 1600/1800 Hz	 AFSK.	 1200  (default)  baud
	      uses 1200/2200 Hz	AFSK.  9600 baud uses K9NG/G2RUH standard.

       -D n   Divide audio sample rate by n.

       -F n   Amount  of  effort  to try fixing	frames with an invalid CRC.  0
	      (default)	= consider only	correct	frames.	 1 = Try to fix	only a
	      single bit.  more	= Try modifying	more bits to get a good	CRC.

       -P m   Select  the demodulator type such	as A, B, C, D (default for 300
	      baud), E (default	for 1200 baud),	F, A+, B+, C+, D+, E+, F+.

EXAMPLES
       gen_packets -o test1.wav
       atest test1.wav

       gen_packets -B 300 -o test3.wav
       atest -B	300 test3.wav

       gen_packets -B 9600 -o test9.wav
       atest -B	9600 test9.wav

	      This generates and decodes 3 test	files with 1200, 300, and 9600
	      bits per second.

       atest 02_Track_2.wav
       atest -P	C+ 02_Track_2.wav
       atest -F	1 02_Track_2.wav
       atest -P	C+ -F 1	02_Track_2.wav

	      Try  different combinations of options to	find the best decoding
	      performance.

SEE ALSO
       More  detailed  information  is	in   the   pdf	 files	 in   /usr/lo-
       cal/share/doc/direwolf,	or possibly /usr/share/doc/direwolf, depending
       on installation location.
