According to "Audio System Design Tool for Teensy Audio Library" the maximum times for delay are:

Board Maximum
Teensy 3.0 139.26 ms
Teensy 3.1 449.39 ms
Teensy 3.2 449.39 ms
Teensy 3.5 1671.19 ms
Teensy 3.6 2413.94 ms


How much can be the maximum delay for Teensy 4.0?

Thanks!
 
I forgot it!
And how much can the maximum delay be if I use the "Audio Adapter Board" with the "23LC1024 RAM memory chip" installed?

Looks like Teensy 4.0 is currently using the limit for Teensy 3.0. I've committed a fix just now.

Of course, you can edit effect_delay.cpp to change this limit to whatever you want.

And how much can the maximum delay be if I use the "Audio Adapter Board" with the "23LC1024 RAM memory chip" installed?

That chip has 128K of RAM, which is enough to hold about 1.48 seconds of 16 bit samples at 44.1 kHz. If you use Frank's memory board with 6 of those chips, then you can have 6 times that much, which is nearly 9 seconds.
