Mp3 and AAC do not add any high pass filter or low pass filters. Uncompressed does sound better but its slight and streaming will probably do way worse compared to anything a compression algorithm will do.

That said, what platform are you streaming to?

I get it. To each their own.

What does mp3do to the audio exactly? Does it apply some audio filter before it is encoded?

I also collect uncompressed music for listening. But that’s a controlled system that I can keep it from being compromised.
I find the convenience a fine trade off for anywhere else. Others don’t.

I imagine the technology will catchup and we will be able to get uncompressed audio in a few years.

I’m still learning about livestreaming, like everyone else these days. Is it known how facebook and youtube encode the audio?
I imagine that’s the 128 aac you were referring to.

Before asking for such things, you'd better check what codec are supported by the most common streaming platforms... If you do this, you will realize that your request is irrelevant.

Audio quality is a matter of many things in the workflow from the mics to the final compression process. If your audio does not sound good, it's probably cause you don't use appropriate equipments for the quality you expect. Moreover, vMix supports VST3 plugins which can help improving the way your production sounds. Anyway the first thing to do is increasing your audio bitrate for streaming and recording up to 192Kbits or even more if you're still not satisfied. But if you feel like you need more, the problem is your equipments, not the codec.

Thanks, earlier today I bumped up the bitrate to 256 but will lower it to 192 since I see that's a waste. I was waiting until Sunday to see what difference that made. I also found playing with the input/output equalizers in vMix helps some, but you can't adjust it too much since it's not that many bands. I raised the last three sliders two notches and can hear C on the organ bass pedals some better, but the lower F tone doesn't come through unless I really crank them up but then it's a muddy sound... I also start getting feedback from where the laptop feeds back into the mixer for playing in-house audio from vMix (audio tracks...)

We use a Lenovo laptop, could the sound card be the limitation? I know I have great sound going into the laptop but I have trouble tracing it through the streaming software. I haven't quite figured out the input/output headphone settings or determined how the sound card plays into this.

I will look into this VST3...

Thanks again



Is your question reversed, though ac3 is lossy it doesn't start with removing the highs and lows so sounds better to me. I love war movies and it's noticeable in the woofer to hear the bombs compressed with ac3 vs aac.

Yes but I think your main problem - since I know now what is your concern, the organ - is most likely the microphone. Capturing audio is an art and it requires good equipments but also a perfect positioning in the space for such an instrument. It's very difficult to capture the whole range of frequencies because not all mics can do it at first and depending on the mic type (omni, cardio, etc...) its position, its distance from the instrument might affect drastically its capacity to "hear" and deliver the whole spectrum. Environnement is also very important... How large is the room, is there natural reverb, how high is the roof ?
We won't solve your issue in the forum, it requires to be in the room and maybe it requires the help of a good audio engineer, but I'm just trying to explain that even with the best microphone and the best soundcard you can get a crappy sound from the organ if the microphone(s) is not at the right place. It's way more difficult than just having a microphone for a person speaking. If the mic is directional or not, its position will differ and impacts a lot on the capture quality. If it's too close maybe it will pick only the medium frequencies (explaining why you don't get low frequencies right), if it's too far it will pick a roomy sound and so on... Like a choir, an organ is very difficult to record.

If I were you, I'd try to find a good sound guy (expiremented with recording natural audio - I mean not a DJ) who can check whether your mic(s) is OK for the job and help you find the best setup for a good audio restitution.
