Set minimum file size for ingestion

[cfc62]

I'm using rdio-scanner with SDR Trunk with NBFM. As it stands today (and may for some time to come), there's no PL or DCS decode on SDRT. It's power squelch - so fundamentally the audio files generated are different from those coming from P25 systems. Not every file is useful - and I suspect this is the case for AM as well, but haven't tried that just yet.

What using power squelch effectively means is that there will be a lot of very small files generated for any transient bursts of RF energy - which happen a lot if you're recording dozens of frequencies. There's really nothing of use in these files, it's just a 40-50-100 ms noise burst. They're small - anything under 1k is completely useless while those files between 1k and 2k are usually useless.

Being able to set a file size threshold for ingestion would be helpful. This would keep the db tidy (it's pretty large even with prune set to 1 day) and keep mp3 to mp4 conversion to a minimum as well.

I don't know if MP3 tags show duration besides integer seconds, I had thought of that as an alternative but a lot can be said in less than a second and deleting them would be bad, I think.

Idealy the recorder shouldn't recorder too short conversation, but that's something doable on my side. I may add some configurable limits in regards to the minimal duration threshold like globaly, per system or per talkgroup.

Thanks for the idea!

Thanks. Agree that the source should not be generating these files, but Denny has been preoccupied with things other than SDRTrunk for a while and I don't think it will get attention for some time.

Ideally we'd have PL and DCS and this wouldn't be a problem, but here we are :^)
