Buffer object, size / number limits?

renalain's icon

Hello,

I am creating a piece which needs 12 different buffers. Each buffer needs to be 20 minutes long (1200000ms) ;(((. I am able to create up to 4 buffers of 20 minutes. Max simply crashes once I create the fifth one. Any idea if there are limits in sizes / numbers or if I should simply use another object?

Many thanks.

Hi, 1 minute of 2 channel buffer needs 20 MB of RAM.
20 x 20 = 400 MB x 4 =1600 MB, so You are still within 32 bit memory usage limit of 4 GB.
32 bit apps can't use more than that.
If You are using Buffers with 4 channels, that would be the maximum, 4 x quad 20 minutes.
If not, then it could be OS problem...

I've been researching this topic for an important project lately. I was able to fit 30+ min long, 96k sample rate, 24 bit, mono audio files into four different buffer~ objects with no problem what so ever. This was in a very beaffy hardware: 32 gb RAM, SSD, Windows 10 PC. Developed in Max 8.2
