Questions on buffering
« on: December 20, 2024, 10:58:47 am »

I have several questions, probably related.

  • In Audio Device settings, one of the Buffering settings is "Hardware". I see three options: Hardware Default, Maximum (power of two), and Maximum. What exactly do these mean? And what is hardware buffering (in this context)? Mine is set to Hardware default. What is that value, and how is it obtained? I'm using CoreAudio, out to a Scarlett 8i6 USB audio interface.
  • In the Audio Path display, I see the following for "Delay:": "228.35 ms from converter; 3989.78 ms from input until heard". I'm curious about the second number, almost 4 seconds. Where is that delay coming from? (Back in Device settings, I have Software Buffering set to 100 ms.) 4 seconds seems - and sounds - excessive. This is a MacMini with M2Pro, plenty of RAM.

I'm trying to understand all this stuff in hopes of minimizing the 4-5 second delay I hear when starting playback.

MacOS 15.2, MC 33.0.30.
