I've been editing a Sherlock Holmes DR; I did notice when I was merging in the readers' recordings, that the volume of the main recording sounded a bit low. When I exported the final mp3 file, it looked fine on the Audacity sonogram, and Audacity said that it could take about 3dB amplification at the most. However, Checker reports a volume for the file of 72dB!

Here's a short sample (which Checker reports as 70dB): https://librivox.org/uploads/xx-nonproject/holmes_volume_test_py.mp3

Can anyone suggest what's happening, please?

EDIT: the sample shows up as ridiculously low volume when I imported it into Audacity again! I'm going to send the whole file to linny for her to have a look at.

EDIT 2: I've got round it by exporting as a FlAC from the apparently normal Audacity file, then importing from the FLAC as a new file, and amplifying from what's obviously a ridiculously low volume. I've no idea what went wrong originally, but it seems to be okay now.

Could an admin delete that file in the non-project folder, please?

I like when Holmes solves his cases. Peter, too!

Thanks, Jo.

It's a problem that I've not seen in Audacity before. It's lucky that Holmes was available!

Have a look at the balance slider on the left of the track. If that’s accidentally been knocked away from the centre position that can mess up the volume.

Thanks for the suggestion; but the slider seems okay.
Just a one-off quirk in Audacity, I think/hope.
