|
|
|
* Name: atest.c
|
|
|
|
*
|
2015-07-27 01:17:23 +00:00
|
|
|
* Purpose: Test fixture for the AFSK demodulator.
|
2015-07-27 00:35:07 +00:00
|
|
|
*
|
2021-09-19 18:51:18 +00:00
|
|
|
* Inputs: Takes audio from a .WAV file instead of the audio device.
|
2015-07-27 00:35:07 +00:00
|
|
|
*
|
|
|
|
* Description: This can be used to test the AFSK demodulator under
|
2021-09-19 18:51:18 +00:00
|
|
|
* controlled and reproducible conditions for tweaking.
|
2015-07-27 00:35:07 +00:00
|
|
|
*
|
|
|
|
* For example
|
|
|
|
*
|
|
|
|
* (1) Download WA8LMF's TNC Test CD image file from
|
|
|
|
* http://wa8lmf.net/TNCtest/index.htm
|
|
|
|
*
|
|
|
|
* (2) Burn a physical CD.
|
|
|
|
*
|
|
|
|
* (3) "Rip" the desired tracks with Windows Media Player.
|
2015-07-27 01:17:23 +00:00
|
|
|
* Select .WAV file format.
|
2015-07-27 00:35:07 +00:00
|
|
|
*
|
2015-07-27 01:17:23 +00:00
|
|
|
* "Track 2" is used for most tests because that is more
|
|
|
|
* realistic for most people using the speaker output.
|
2015-07-27 00:35:07 +00:00
|
|
|
*
|
|
|
|
*
|
|
|
|
* Without ONE_CHAN defined:
|
|
|
|
*
|
|
|
|
* Notice that the number of packets decoded, as reported by
|
|
|
|
* this test program, will be twice the number expected because
|
|
|
|
* we are decoding the left and right audio channels separately.
|
|
|
|
*
|
|
|
|
*
|
|
|
|
* With ONE_CHAN defined:
|
|
|
|
*
|
|
|
|
* Only process one channel.
|
|
