How to use raw files #19

Closed athoik closed 6 years ago

athoik commented 6 years ago

Hi @JvanKatwijk,

First of all thanks for the great job you are doing with DAB/DAB+.

I would like to know how can I use the samples with raw files (eg like the ones available here: https://sdr.kt.agh.edu.pl/sdrdab-decoder/download.html#download-data)

I would like extend a small plugin for Enigma2 (https://github.com/satdreamgr/SDGRadio) with DAB/DAB+ and your repository seems the most promising.

Currently I have manage to compile example3 (with -DWAVFILES=ON), but samples are not recognized.

# dab-files-3 -F ./antena-1_dab_229072kHz_fs2048kHz_gain42_1.raw
dab_cmdline V 1.0alfa,
                          Copyright 2017 J van Katwijk, Lazy Chair Computing
opt = F
file ./antena-1_dab_229072kHz_fs2048kHz_gain42_1.raw no legitimate sound file
allocating device failed (24), fatal

Once again thank you.

Good question,

The "wavfiles" is for regular sndfiles (PCM files with a rate of 2048000). Never got the question to add iq or raw files, you are the first. I'll handle it coming week

You could give it a try now. it is called RAWFILES and it compiles well for example-2, 3, 5

I never use the stdout output, so it might be - unlikely but you never know

And it works!

Great job, now I have to see the other examples (scanning, finding channels, etc).

I had nothing serious at hand, and it seemed a rather illogical omission, so ....

Anyway, have fun
