  Dire Wolf is a software "soundcard" AX.25 packet modem/TNC and APRS encoder/decoder. It can be used stand-alone to observe APRS traffic, as a tracker, digipeater, APRStt gateway, or Internet Gateway (IGate). For more information, look at the bottom 1/4 of this page and in https://github.com/wb2osz/direwolf/blob/dev/doc/README.md

Project mention: What signal is this? the frequency is around 144.8 and I am listening from Bucharest. the only sound i can compare it to would be a velociraptor noise. the second image shows a sound that sounds like white noise and happen much more frequently. thanks in advance for anyone who helps! | /r/RTLSDR | 2023-06-04

144.800 is the APRS frequency in Europe. That's part of the 2m amateur band, and you can use tools like Direwolf to decode the packets. See https://aprs.fi/ for a display of the packets that make it to the internet.
