hey,
I have a 2h mp3 track that I imported to Audacity and I just want to add 5h of silence before the mp3 track starts.
To do so, I selected the beginning of the track and added 5h of silence via Generate > Silence. It all looks good but when I export the entire mp3 and play it, the silence seems to end much earlier than the 5h.
The exported mp3 has much less silence (around 2h45) than the expected 5h … what is going on?
I’ve just tried again with a 1h silence + 1h of my original sound (which is a hairdryer sound) and the same occurs. The hairdryer starts playing after 27min and not 1h as expected.
Yes. So I am able to duplicate this issue. On VLC, the file plays as approx 30 minutes of silence and 1:30 of hair dryer. So there seems to be a bug somewhere in VLC.
Microsoft Media player does something similar, so perhaps they are using the same MP3 decoders. However, MSMP crashed, rather than spitting out an error message so there seems to be a bug there.
Foobar2000 and Power Media Player do the the same thing as Audacity. So this gets Audacity off the hook. I am not sure what else to add, if anything.
