Audacity Forum

Hi,

Is there a .wav file size limit for two channel stereo? lemme back up... I have this extracted stereo wav file that is 735mb. I've processed it in audacity normalizing and removing noise. When I select the 'track' (as 'one'- right/left channel stereo 'track') and 'export selection', once the file is saved, the 'stereo' .wav file becomes only left channel 'mono'. Once saved and reopened up, the right channel is at '0'db. From the source .wav at 735mb, the saved (unwanted single mono track) file is only 2kb off. Trying to guess if this is a file limit something or an audacity thing, not sure, I'm not that often working with .wav files this size. Audacity ver is 1.3.4 beta, never seen this before. Haven't been hanging around the forums recently to know if this is a common issue with .wav (if so by filesize) or anything else. I haven't changed any preference settings in Audacity (from default or the few tweaks I make), etc. Source wav is 48khz, .wav; writing out a 2 channel 48khz .wav. As described, this make any sense?

Thanks,

The absolute largest a standard WAV file can get is 4GB due to the internal structures. Some systems limit file sizes to 2GB.

You may be running out of hard drive space. The machine must be able to handle high quality fast data some three or four times the size of the show. Do you have 4GB of high quality, error free, defragmented space left on your hard drive?

Hi Koz, thanks for the reply and the .wav file limit info. Yes, I've got 100gb free on a 500gb drive, windoze doesn't need to defrag (checked.) Maybe there's something up with the way the original file was encoded. I've now checked some other recent work I've done and other files don't have the 0db right channel. Going to open things up in a hex editor and see what I can turn up. If I ever find the problem, I'll reply to the thread. Thanks Koz.
