[Jackaudio] About Jack Capture and Playback Latency

Hi, Thank you for your great support in Jack. I am trying to build a real-time application on basis of Jack Server and Client architecture. But Jack capture and playback latency is failing me to make the application sample accurate. *JACK server starting in realtime mode with priority 10self-connect-mode is "Don't restrict self connect requests"audio_reservation_initAcquire audio card Audio0creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|32bitconfiguring for 48000Hz, period = 1024 frames (21.3 ms), buffer = 2 periodsALSA: final selected sample format for capture: 32bit integer little-endianALSA: use 2 periods for captureALSA: final selected sample format for playback: 32bit integer little-endianALSA: use 2 periods for playback*
