Hi all

I searched this forum to find the lowest obtainable end-to-end latency using Teensy 4.0, the audio adapter board and the audio library. I found some posts a few years old, but no very new. Obviously both buffer size and sample rate are important. With Teensy and the most recent audio library, what is achievable? How many buffers will always be in processing when using the library? 2? More?

Am I right in assuming that: minimal latency = 2 * blocksize / samplerate? And that 16 sample buffers at 44.1 kHz is no problem on Teensy 4.0 when only doing 'light' processing (simple iir filters and some nonlinear distortion).
