I think I may have an exception, because the particular code which is temporarily using more blocks uses only input and output queues. All of the signal processing is done in the sketch. I am going back and see if I can throttle down the maximum...

No, it won’t free blocks. In fact it’ll waste all but the last-created set. If you look at the contents of AudioStream.h you’ll see it’s not a function but a macro which defines a static set of audio blocks and then initialises them. Assuming...

Maybe I have to create a class which inherits from AudioStream? Then make a new method to free "num" blocks? There are protected methods which do this, but for only a single block. Since "initialize_memory()" is used by the AudioMemory macro...

That’s the meaning of static! Well, for variables, anyway…

Yeah, I discovered it's a macro from calling AudioMemory() from within other functions. The heap gets eaten up without even calling those functions!

I am working on the T41 radio project which uses the Teensy 4.1. What I want to do is conserve memory, but I have a function called only occasionally which uses a lot of audio memory. So I want to temporarily increase the number of audio blocks...
