I see that MaxMSP has delay line objects. How long can I make a delay?
Delay lines are stored in the memory of the computer, so the maximum delay time is limited by the amount of memory you have available. A mono delay uses 1MB of memory for each 5.94 seconds of audio. So, if you used 32MB for a delay line, you would have a delay line of more than three minutes (190 seconds). You can have many taps off the same delay line without using additional memory.
