Request to add Raw file support for .wav file format?
Version: 2.5.0
Hi, I use raw files for learning and testing, because I can't receive DAB signals in my area. welle-io supports .wav. The raw file I downloaded from the Internet is in WAV format, which has a DSCTy:60 sub-channel, but Welle-io does not have the announcement epg display function, so I came here
Settings... -> Device -> Raw file -> Open File... only (*.bin *.s16 *.u8 *.raw *.sdr *.uff), but not *.wav
welle-io

The dab raw file source I can find:
https://www.sdrangel.org/iq-files/
(Digital Audio Broadcasting (DAB) BBC Radio Multiplex)
https://github.com/williamyang98/DAB-Radio/releases
(baseband_9A_0.zip
baseband_9B_0.zip
baseband_9C_0.zip
baseband_9C_3.zip
baseband_dab_uk_sdrangel.zip (BBC))
You are right, the file filter is limiting in this case.
As workaround you can rename the file to *.raw, choose number of bits (16 bits in the BBC recording you refered) and it should work although first bytes will be rubish but it is not important.
Development version of the application supports opening WAV files as raw files. There is not specification for WAV file header for SDR purpose (auxi chunk), closing the issue.
