Thanks for the patch,

I try to open a 1 hour file with my "bigwave" patch, and it work perfectly. I don't need to see the waveform.

I make a vanilla patch to open a stereo audio file longer than 4000000 samples.
His name is "bigwave" : bigwave.zip

I work mostly with long stereo files, so I use this all the time.

I share it with you.
I hope you enjoy
