I have also wanted this,
In the mcu datasheet a Sdram interface is described,
It means we could at least have 32MB extra ram that is much faster than a psram.
And maybe 32mb is enought to buffer data from a sdcard?...
in the TT1060 datasheet
there is two separate SPI units called A and B
they can be mapped to different pins
(not sure if the pin mapping is available in the Arduino framework)
I have done a 80key velocity sensitive piano keyboard scanner using 2x10 74hc165.
So 8x 74hc164 is not that much,
and you could read them in parallel by using 8data+clk+latch=10 pins of the teensy.
You can read...

ESP-09 is the smallest I have seen measuring (10x10mm)
but it's needing a pcb to make the mounting easy,
it have enought pins for a microsd-card

I don't really understand how digitalWriteFast should make it faster,
it's fast for the first set of pins
but for pin 54 it have to go through all the first 0-53 pins so there is a shift in time which pin you use, ...

there are 3 things that needs to be copied for a complete node:

I looked at the source before, and you already have custom names, what I mean was to have them separated in different files, I have noticed that Paul also puts many classes in the same file, I think that's making it...

How do you define a clipped audio signal, and how do you then play synth-music that contains sharp edges.

The "line in" is not that 3.5mm, that is the lineout
Search for teensy audio board line in. An if you are trying to mix the two signals (both from teensy and Bluetooth receiver) you should use two resistors
Its hard to analyze the problem without AudioOut class code. Right now it seems like you are making a connection to the AudioOut class and if that class is not inherited from AudioStream that is one "problem"
/Jannik
Actually of what I understand the float value is never used between audio objects, float is not a good way of storing audio values because of its structure.
The floats are only used to make it easier for a user...
