Bad sound quality

[fredisz]

Hello,
since a few weeks i noticed that the sound quality got more worse. (or I think it could be better) I don't know why this happend.

Of course I also tested listening with other clients. I tested other radio stations and music files from youtube.

Please test and compare with a manually uploaded file.

At the moment it is the case that radio is more worse than downloaded music and streamed music from youtube. No matter which radio station I play. But I think also the normal music could be better quality, if more people are on the teamspeak, if only me and the bot is online the quality of normal music i think normal, but in this case the radio quality only gets a little better and not normal

I also set up a fresh TeamSpeak Server and a fresh Sinusbot on another server, here it is the same.

No offense, but I asked for a specific test for a reason...

Radio can have different bitrates and ytdl downloads different audio files as well. A test with a manually uploaded file would really help.

Please first notice the edited last answer from me.
Yes, I tested that I heard the file on my PC and then I heard it via Sinusbot on TeamSpeak. But now I think when nobody is at the teamspeak except the bot and I, the quality of downloaded music is normal because teamspeak at Opus Music 10 is limited to 97,23 kBit/s. But if only two or three people more are at the Ts you instantly notice that quality get a little bit more worse and it hangs sometimes. The same happens when I play radio, but radio is always really bad quality.
