hi.
i have 320kbps MP3 high quality music.
use for live stream background music.
for sure it is possible to add not re-encoded audio to video (just mux as ffmpeg).
but OBS encode music and in result in stream i see music with absolutely distorted high frequencies (no mater what bit-rate i set in OBS).
please help me to fix. i see many streams with good music quality.
i can't prepare local video file coz i use browser plugin to capture real time things for stream (with background music).

this is all on VPS server.
tried same on my home PC and quality much better.
from VPS sounds like 64kbts. from PC like 128kbps (at least possible to listen this).

maybe i need to install some codecs like "k-lite mega codec pack" on VPS?
Windows Server 2016. it is not "home" or "multimedia" version of Windows and perhaps it does not contain something for high quality sound encoding etc.

OBS will always re-encode everything it sends. If you want a bit better audio encoding, install the coreaudio codec: https://obsproject.com/forum/resources/obs-studio-enable-coreaudio-aac-encoder-windows.220/

Running OBS on a VPS is not recommended/not possible, because a VPS doesn't usually have hardware devices for graphics and audio. If you connect to your vps via rdp and you redirect the local audio to the rdp connection, the rdp connection replaces any audio device and installs a software emulation. The quality of the redirected audio is not suited for music. And the stream will stop the moment you disconnect the rdp session, because in this moment the rdp audio device is removed from the vps.

i use rdp only to manage windows. nothing stopped when rdp slosed. music paying with VLC plugin and no matter open or closed rdp is.
no need in hardware coz audio and video encoding software and all works. but sound with poor quality.
