You can do this in VLC, though it’s not very practical. VLC’s equalizer has a preamp slider, it’s just not great if you want to change it all the time.

This is pretty cool, thanks.

If you decide to set up an SDR for ADS-B, you might want to consider setting up a WebSDR with something like OpenWebRX. This would let people listen to all the signals in the bandwidth that you set.

If you’re interested, receiverbook.de is a list of most WebSDRs.

Ahh, sorry my mistake. I remembered reading a headline somewhere about Google having already implemented it, but I didn’t check. Thanks!

It has allready been implemented in Chromium/Chrome (link). Websites only have to start using it.

Edit: see comment

I know as little as you do about selfhosting, but I just want to point out, if ip a generates a convoluted/confusing output, I would recommend using hostname -I instead. It just prints out all your IP-addresses, with no additional info.
