decode aac file causes audio noise.

We use aac.js to decode some aac files but found weird situation.

aac.js can decode aac file and sounds ok when file is encoded by bitrate 64kb, sample rate 48000, channel 1. We low the source bit rate to 32kb with same sample rate, channel. The output has noise(it seems high frequency sound become noise).

The 32kb sample file is here

Your sample file is 404ing now, but try the new version after #10. Maybe that was causing your issue?
