Re: AIFF audio file causing endless loop

[Brian Whitman]

It's a bug in SubbandAnalysis -- _NumFrames is a uint, but we do 

    _NumFrames = (_NumSamples - C_LEN + 1)/SUBBANDS;

That sound is 16 samples long, so NumFrames overflows and the assert on the next line doesn't fire. I would put a check earlier on to not allow any sound under 5*11025 samples or so , but even a C_LEN+2 (130) sample sound should at least go without crashing.

Hello,

I'm using the echoprint codegen version 4.12 and have compiled it for Mac OS X. It works well for most of my audio files but now I found a file that's causing problems. The file "noise.aif" I attached is a very short AIFF based audio file taken from the test suite of taglib-1.8. (tests/data/ directory) If I run codegen on this file it will eat up all of my memory and all of my CPU. (8GB and 199% CPU on my system) No result will be shown and it appears to be stuck in an endless loop.

Is this a known problem?

Greetings,

Marcel.
