Choppy Audio #75

Open LD723 opened 7 years ago

LD723 commented 7 years ago

Im decoding a p25 tunked system using unitrunker and DSD. Sometimes the decoded audio from DSD sounds very choppy. And happens a lot with different p25 signals whether it be trunked or not. I don't know if its an error in the decode or something but I do get little errors and sometimes the R and M symbols but I can't tell why since the signal is pretty strong.

EDIT I just found out when the audio is choppy it sometimes says Non-standard IMBE c0 detected, skipped. Or it also sometimes says Ignoring LDU2 not preceeded by LDU1.

Does that mean the signal is bad? When I listen to my own recorded raw audio the actual raw audio sounds pretty strong and barley any static or signal drops.

Forgot to mention the audio also has a crackle in it too. It's not super loud though but it's starting to annoy me hearing for too long lol
