how to load file more than 20hours long

[ID228423666yqo]

Hi, is there any solution to load file 20 hours long in Adobe Audition? I want to cut this to pieces about 1 hour long.

Audition works with the Broadcast Wav spec which allows much longer files to be loaded, and that's important, because whatever format your original is in will be decoded to this anyway. Have you actually tried doing this?

I've loaded file in MP3 spec, so should I konvert it to WAV spec?

If you have managed to load it into Audition, it will automatically be a wav file - you don't have to do anything. If you subsequently split it into one hour segments then the initial save of these should be as wav files, and you can then make distribution copies from that if you need to. The reason for doing this is that every time an MP3 file is opened, it is freshly decoded - and every time you save a file as an MP3 it's re-encoded. Every time you do this, the quality drops, so you do it as few times as possible. Saving as a wav file results in no degredation, as it's an uncompressed, lossless, format.

Ok I didn't know that, but can You tell me what I should do to open whole (20 hour) file because at this moment I can open only 9 hour?

Not quite sure why that should be, but probably your best approach would be to use an MP3 splitter app (these are very limited in what they can do, but they should all be able to do splitting) to split your file into, say, three separate files, and work from those. Look here.
