Hi, would anyone know how I would save the frame that is decoded with atest? Currently atest -B 9600 -h only prints out the frames, I was wondering if there is a simple way to save the decoded frames? Thanks!

If you read the man page on "atest", if gives you an example of how to generate a test file and later decode that test file.? Are you looking to save the decoded text like shown below into a file?? If so, you could just use:

?? atest -B 9600 -h test9.wav > test9-wav-decoded.txt


Maybe you're wanting something like saving to a pcap file (readable by tcpdump, wireshark, etc?)

?? 44100 samples per second.? 16 bits per sample.? 1 audio channels.
?? 32576 audio bytes in file.? Duration = 0.4 seconds.
?? Fix Bits level = 0
?? Channel 0: 9600 baud, K9NG/G3RUH,? , 44100 sample rate x 3.
?? The ratio of audio samples per sec (44100) to data rate in baud (9600) is 4.6
?? This is on the low side for best performance.? Can you use a higher sample rate?
?? For example, can you use 48000 rather than 44100?
