That's a different knob that can be used; Increasing buffer size simply is a different compromise to achieve the result of meeting audio deadlines.

Quality vs latency, pick one.

Or just use PREEMPT_RT to tighten the timings for the critical audio worker getting the cpu ;)

    JERRY: We didn't bet on if you wanted to. We bet on if it would be done.

    KRAMER: And it could be done.

    JERRY: Well, of course it could be done! Anything could be done! But it only is 
                  done if it's done. Show me the levels! The bet is the levels.
Again, the point isn't that there is a possible tradeoff to be made, nor that the configuration option isn't available, nor even that some people tweak that setting for this very reason. It was stated that better RT performance will automatically improve audio quality because the audio system may automatically switch resampling methods on xrun, and that is specifically what I'm doubting.

The bet isn't that it could be done. Anything could be done! Show me that it is being done!

    A true audiophile can tell.

    Nevermind switching approaches to interpolation; The microjitter is blatant, and the plankton is lost.

      Wow, we got a No True Scotsman right here. On a more serious note, why would there be (more) microjitter? Isn't the defaut reaction to jitter to automatically increase buffer size as stated above?

        >On a more serious note, why would there be (more) microjitter?

        This was audiophile bull for the sake of entertainment, if not clear enough. There wouldn't be any more or less jitter with or without RT.

        It is the same samples, and these samples are not played by Linux, but by the DAC, which has its own clock.

        >Isn't the defaut reaction to jitter to automatically increase buffer size as stated above?

        I suspect you mean buffer underruns. A non-toy audio system will continue to try its best to deliver the requested latency, even when these have already happened.

        In the same manner an orchestra won't stop just because a performer played the wrong note, or was off by half a second.

      Does a true audiophile need cables made with 99.9% pure silver to tell, tho?
