What do the new audio options mean?

Recommended Posts


guys I do not know if I'm writing in the right section, but I would like to get more awareness on the use of the PA audio options and then I need help explanations:

-resampler cutoff frequency ratio: default 97.0%. increasing or decreasing the percentage what happens?

-size audio buffer: buffer ms ... increase ms that happens? number of DSP buffers, increase decrease that happens?

-visualizator delay: extra delay ms, better for high or low audio?

thank you so much D

Buffer size compensates for slower devices and/or file systems (or larger high-res files) where the file data sometimes cannot be fast enough, and increasing it should help avoid buffering/stuttering issues during playback.

Visualisation delay adjusts how much of a delay is applied so that the time taken for complicated visualisation effects and/or complex audio decoding match, so that the visual highlights occur in sync with the audible music output.

thanks Andre
so, "buffer ms" and number of DSP buffers increase in case of stuttering 
and if you do not have it you can lower it if I understood correctly?
the delay viewer instead is only if you watch videos or video effects? 
I only listen to music and turn off the screen can I keep it at 0?
sorry, but maybe it can come in handy for more "curious" people

Yes, if you've got the visualisations turned off there's no need to adjust anything in that setting.

And increasing the buffer is only worth doing to fix an audio glitching problem, if it plays perfectly anyway there's no need to adjust it.
