Title: Analyze Audio Problem on Big File
Post by: JimH on January 24, 2005, 09:28:04 am

1. Analyzing large files, > 100 MB (mixes), hangs around 40%, sometimes the whole system freezes.

mkutsen,
Thanks for the link.  I downloaded the file, imported it into MC11 and did a right click to analyze.  It worked for me.

This is something i have never done with MC. I felt the BPM would not be useful if there were changes in tempo, which they will be invariably. I waited for cue to be implemented so i could analyse on a track by track basis.

Volume normalisation is one benefit i suppose but then if its > 100 Mb, usually the volume does not shift too much (within the mix).

These files are good candidates for Mp3Gain (http://www.geocities.com/mp3gain/) which will actually modify the volume setting of the mix so it sounds the same on any player.

I have analyzed big MP3 files (up to 163 MB) and even bigger APE files without problems. Years ago MJ/MC had problems with analyzing thousands of files in a batch. I think it was fixed then and nobody has reported it since.

Could it be a memory or other stability problem? It is an intensive task, which maximizes CPU utilization.

Jim,

Thanks for checking into this.  I don't even know where to start looking.  I have 1 GB, Audigy2, and P4 3.4.  My motherboard drivers and BIOS are pretty recent and the latest set of Audigy drivers.

Thanks again,
Mike

I don't know either, but if I had to guess, I might think about a memory error, or not enough swap space.

How much swap space do I need?
