Issue with encoding stopping when volume is too high

Mathew Thompson
Hi there,

We've recently been experiencing an issue with the LAME MP3 Encoder and
were wondering if you could offer any guidance/workarounds.

Basically, we record WAV audio using Flash from all of our users. We then
use LAME to encode that WAV to MP3 and all works fine.

However, if the captured sound levels are too high (for example, blowing
directly into the Microphone) the encoding will stop completely resulting
in a clipped file. This doesn't happen with the WAV that's recorded, I just
wondered if there was any tweaks/workarounds I could use to accommodate for
this? Something like allowing the level of the encoded audio to be higher?

Thanks for the help,
Mathew Thompson

Can you tell us what LAME version you are using and how you utilize it?
What does your command line look like?

Do you have some small wave file ( < 10 seconds ) which demonstrates this
behavior, and can you send it to me?
