There are a problem with 'stdout.wav' and automatic second pass for overflow.
When this occurs the output is duplicated but the corrected second part is out of sync (because the second header) with garbage result.
Seems the problem is solved when add -2pass or -normalize parameters. Now seems the first ouput is inhibited and only the second pass is really output.
I say 'seems' because a second problem: when use 'stdout' there aren't log and the user don't know what happen.
There are a method to cancel the automatic second pass for overflow?
Many times are little peaks (<0.1dB) due to imperfections in lossy codecs than can be assumed.
