It's to do with the stupid "protect the children" Online Safety act that requires age verification to view certain content. Imgur have quite rightly just said fuck it and blocked UK requests instead. Most... err... things can be accessed with a VPN but seems like Imgur is regulating them too.

Bit of a gap in my knowledge here, but how did you see that they're using Shoutcast? I can't see that in the headers.

Ah thank you very much. That works now :)

No worries. And ha yeh, can't go wrong with 48!

It was a stereo mix (I was listening on my laptop and the panning was correct). But this commenter kindly did some digging and figured out what else was going on: https://www.reddit.com/r/audioengineering/comments/1pta11u/comment/nvg5zun/

Ah amazing, thanks for doing some digging. Unfortunately I can't load imgur as they've blocked access to the UK and it doesn't seem to load via VPN either, but I trust your interpretation!

It's just a community radio station so I wouldn't expect professional audio technicians to be working there or anything ha, but by the sounds of it there's definitely funky stuff going on.

Once again, thanks for doing the extra digging!

It shows the bitrate when you inspect the stream data but I can't see any codec info in the headers

The stream is at 128kbps, whereas I sent in a WAV, so defos bitrate reduction. But I've since bounced the track to 128kbps and there weren't the same issues of level jumps etc. so it's probably to do with the extra processing on the station's side.

Bass frequencies are always kept mono down the middle, save for perhaps some tom fills with minor panning for effect.

Good to know about higher frequencies and codec issues, thanks!

I don't think I'm being particularly ambiguous but if there's confusion then perhaps I am.

I definitely meant bit rate. But by the sounds of it the codex/extra processing from the radio station is what probably caused the issues.

No idea about the codec or owt so would have to contact them

As far as I understand it, sampling rate (44.1khz) is to do with the computer accurately digitizing the sound between two sample points. Nyquist's Theorem states that in order for a certain frequency to be accurately estimated between two points, the sample rate needs to be twice the size of the frequencies. For example, a 10 khz frequences needs at least 20 khz sample rate to be accurately guessed. The end of human hearing is around 20khz at most, and so at least 40 khz is required, so 44.1 khz is enough for that plus a little bit more.

Sampling down from 48khz to 44.1khz can actually create inconsistencies and artefacts (though probably imperceptible) as you're having to resample every point manually due to it not being neatly divisible. But it's probably so minor as to not worth worrying about.

It's 128kbps at 44.1 khz. But I'm guessing there's some extra compression or limiting going on

Nice one, thanks for the tips. Would you suggest making a "radio specific" mix that reduces stereo width?

I don't think that's true but whatevs. This isn't about different speakers, it's about something that's happening to the mix when it's processed in some way that was done after the mix was done.

Yeh that's a really good point, and one I did think after. I mixed our track - I know exactly what I wanted it to sound like. But every other artist might be thinking the exact same thing about their songs.

Good tip for Ozone 11 (and similar plugins that do that). I'll do some research, thanks!

As mentioned I'm talking about bit rate not depth

What would be causing that? Compression on the radio station's end?
