libsndfile can be used to open a UNIX-style pipe
 2014-09-14 17:02:07 -04:00
midnightmagic fd998e2bf7 libsndfile can be used to open a UNIX-style pipe on many platforms 
In specific, it can be used to read in data almost directly from Gqrx
Currently, this will not function correctly using -i /dev/stdin on OS X
because stdin is not seekable, and it is not actually a file; also, for
ongoing raw data, there are no hints for libsndfile to identify the
sample.

So, we can use the UNIX-y '-' to do libsndfile-approved fd handle open.

Tested with the dsd-samples wav after converting it to correct sampletype
(stereo) -> sox p25_raw_unencrypted_edf.wav -c 2 ~/gqrx_last_recorded_filename.wav
.. and then pressing 'play' in the Gqrx interface while running:

socat udp-listen:7355 - | dsd -i - -o pa:2

.. in the background. And it decoded it nicely as many times as I played it,
which was 5 or 10.

Portaudio support
 2014-06-09 15:50:52 -04:00
Jiri Wichern 74fa117850 Tweaking the delay a bit... 0,050 s for output seems too little; it results in choppy audio and ultimately, a heap of errors. 0,100 seems ok for the output buffer. But the input buffer needs to be much larger else it overflows. Also, an extra stop stream before terminating to make sure all audio from the audio buffer is played. 2014-06-07 20:49:35 +02:00
jpwichern 5dd236ec96 Update dsd_audio.c 
Small oops
 2014-06-06 17:26:50 +02:00
jpwichern 55b190ef49 Update dsd.h, dsd_audio.c, dsd_main.c and dsd_symbol.c 
Adding portaudio support. Implementing it as a new audio_..._type in dsd.h.

Update CMakeLists.txt and create FindLibPortAudio.cmake

robotastic d077cd8316 Fixes a crash if an irrecoverable error happens 
If an irrecoverable error happens, you should start a new sequence
since the previous dibit was not set

Jared Szechy 4e338dede9 Fixed file output directory. 
- This fix is very minimal, as a result output directory arguments
    must have a trailing slash.

Fixes #34

EdFuentetaja 9e6b3b7978 Included error correction on P25 TDULC. 
Added a new "heuristics" module for P25 that improves the estimation of the symbol (dibit) that corresponds to a given analog signal value.
Added a BER (bit error reate) estimation for P25.

EdFuentetaja f8cd8d715f Added error correction to the metadata of LDU1 and LDU2. 
Refactored implementation of p25p1_ldu1.c and p25p1_ldu2.c. There are less duplicities now and hopefully is easier to read and maintain.
Added a unit test for the Hamming algorithm.
