We have built a simple recording application in Max. Its main focus is to record audio from 1-4 microphones. The audio sessions we record are long, usually a minimum of an hour - but can be upwards of 3 hours in duration and the aiff files we create can be very large. In our application, we have a very simple 'timer' that essentially counts up (in seconds) the duration of the audio session we are recording. The timer function is a simple pass to the browser that our application presents to the user. Max in called from the application and we post back and forth into Max things triggered in the application.

The issue is this - when we run a test with the system we will record a long audio sample. Usually the best test is to place a number of youtube videos in a row and the application merrily records what was being said. Every time we run the test, the timer stops at 6 hours, 45 minutes and 45 seconds (24345 seconds) exactly and the recording stops as well!! At that point, the aiff files are saved to the disk and are about 2GB (2,096,956kb) for each channel (microphone) we had running.

We've attempted to run this inMax 64bit as well as 32bit with identical results.

Our guess is that the buffer is getting full and has a hard limit of 2GB and crashes the system out - or hangs it - but we have no idea and we are really at a complete stand still.

Any help / guidance / directional assistance is warmly appreciated!

Thanks for this - but we are using Windows 8.1 N 64bit and we have duplicated the issue in both versions of Max 7 (32bit and 64bit). Your link is helpful - and I appreciate it - but it is not quite the answer to this issue.
