Good evening Elektronauts. I have a mastering question.

Bandcamp.

You can upload 48kHz 24bit wavs, which are unchanged if the purchaser downloads them as far as I’m aware. So I can happily master to -0.2dBTP at whatever loudness I like for this purpose.

BUT the platform also transcodes to MP3 for download, AND for streaming.

So - perhaps I should master to -1.0dBTP and ensure my LUFS are within some range to avoid inter-sample overs and get max dynamic range within the LUFS recommendations?

I’ve searched the web and the Bandcamp help centre etc and cannot find any info apart from this meagre offering:

We don’t have a recommended LUFS level for your uploads. Our encoding process will leave the audio unchanged, so that loudness level is up to your discretion. We slightly lower the default playback volume of the website player to better support a wider range of computer speakers and headphones, but that won’t affect downloaded audio. Feel free to go with whatever sounds best to you!

From here: https://get.bandcamp.help/hc/en-us/articles/23020678953367-Is-there-a-required-LUFS-setting-for-my-audio-files

Does anyone have any insight or advice about mastering for Bandcamp please, particularly for dBTP levels to avoid inter-sample overs & resulting distortion?

Thanks!
