I brought this topic up a bit ago and kinda settled on things sticking to 44100 Hz. In the latest release, there’s a selection in the streamer module for 44100 Hz, Optimal, and 48000 Hz. I was experimenting with this and found that even at the manual selection of 48000 Hz, the actual stream was still at 44100 Hz. I use both 64 HE-AAC and 128 LC-AAC streams. I have audio flowing in all at 48000 Hz, and I assume the SRC inside BaO is converting to 44100 Hz for the actual stream. Ultimately, even selecting the 48000 option is not outputting a 48000 stream. If, for whatever reason, I do need a 48000 Hz stream, BaO will not allow it. This may be a bug or some limitation in the encoders in use, I’m not sure. I’d love to have someone (Leif maybe) have a look and test this to see if it’s a bug or as designed, please. Thank you!
I remember you raising this and I put it directly to Leif.
I usually stream at 48K using AAC.
I have just opened my stream (via BARemote) and tried AAC and HE-AAC at 44100 and 48000 rates and listened via the VLC program to my own stream. If I click on “Tools/Codec Information”, VLC accurately reports both rates correctly. In other words, it is correctly collecting and playing at whatever rate I select in BA1.
I am not using a streaming service, but connect to VLC via a private URL, directly to my home music playout system. I also use it on my phone and Bluetooth it to my car sound system.
So, that brings me back to the differences between what I am doing and what you are doing. Are you streaming through a service like Icecast? Could they be down-converting it? Do you have your Windows sound devices aligned to 48Ks? Similarly, your soundcard setup. If any of these are locked onto 44.1, Windows will down-convert it.
I am reluctant to report it as a bug, as it seems to work fine in my case, but I am happy to work with you to track down the problem.
I appreciate your help! Yes, everything on my system from the automation output, to the outboard processing I’m testing (Chameleon C6s) into BaO is all 48000 Hz. When i selected the stream settings for the encoders to 48000 Hz, and hit connect, it connected and was streaming, but the players (several) all reported 44100 Hz. I have used other streaming tools, like altacast, BUTT, etc, and they all allowed 48000. So it’s not a limitation of my streaming host/provider. I’ve taken a screenshot of all the audio settings I could show on one screen. I switched it back to optimum now as I gave up on tweaking with a “production” stream that I don’t want down for long. It’s not a huge deal, but for some reason, if I want/need to go to 48000, I should be able to?
Here’s that screenshot: https://drive.google.com/file/d/1MC514wFhryKjIoGNyIlYiQRtpTeQgTUD/view?usp=sharing
I’m fiddling some more.. I’m finding that the long cache/delay of my stream host was keeping me from seeing the new stream right away. In other words, I was being impatient. I was wrong. It does appear to be working… i’ll keep an eye on things… Thanks again.
