A related question, is there a ready solution to do constant recording using some Linux box (e.g. Raspberry PI)?
AFAIR I've seen someone recommended such software on HN but I can't find it right now, it was something for recording radio stations or similar.
I would like to get some kind of sound monitoring of my house when I'm away or sleeping and besides using arecord I couldn't find anything useful.
- habibur 4y agoAn old laptop will work better. Raspberry pis don't have Audio in. You need USB microphone and drivers, which are hit or miss.
- jxy 4y agoI was playing with this idea of recording everything using a 1st gen AIY voice kit. The driver is a linux kernel builtin module. The recording quality is good if I'm in the same room. But I didn't find the recording that useful, so I stopped doing that.
- krzyk 4y agoWell yeah, but I wonder what software to use for constant recording that could be worked on outside of the recording process.
- reisub0 4y agoEven better is something like the Guardian Project's Haven(https://github.com/guardianproject/haven https://github.com/guardianproject/haven) which IIRC Snowden contributed to. It's incredibly cost-effective to just buy an old Android phone (which comes integrated with multiple microphones, with good signal processing and noise cancellation), instead of building it with components. Haven is specifically designed for intrusion detection, and for preventing people from tampering with your laptop for instance by detecting activity on the Android phone's sensors.
