Skipped, too quiet

[baqwas]

Hello,

All my ogg -> wav files are being reported as "skipped too quiet" yet I can hear the files using the headset/microphone (without volume amplification) that was used to capture the audio.

Is this an operator/user error? Apologies for posting it as an issue. Is there a tool that you recommend to convert the wav files to a higher volume setting? (Again, my ignorance about wav files is on full display).

Kind regards.
