    Hi Zuzler,

    MPAR uses a software solution - the actual resampling is done using the SoundTouch library (http://www.surina.net/soundtouch/) and the define for no crossover click is on.

    I must say I haven't heard any clicks for a long time (the earlier versions of SoundTouch) - but it might be worth hunting out an older version of the dll from area 51. I seem to remember only changing the interface one so, hopefully, most of the versions are still compatible.

    Parsing the detailed logs for MPAR is no fun - and you'll need a fast SSD to even be able to produce them (they were primarily to detect drift rather than monitor quality. I'd recommend using <Shift>1 to get the onscreen diagnostics and see if there is a pattern between the resampling adjustment and the clicks. Although in the logs given, MPAR wasn't active and the Default was used.

    David

    I have click on my side (most often when there is an action movie) and most of the time by disable 'timestretch' function solve the issue but kill MPAR feature.

    Oh, a new version of Soundtouch v1.8 ( 7/01/2014)
    • Added support for multi-channel audio processing
    • Added support for cubic and shannon interpolation for rate and pitch shift effects besides the original linear interpolation, to reduce aliasing at high frequencies due to interpolation. Cubic interpolation is used as default for floating point processing, and linear interpolation for integer processing.
    • Fixed bug in anti-alias filtering that limited stop-band attenuation to -10 dB instead of <-50dB, and increased filter length from 32 to 64 taps to further reduce aliasing due to frequency folding.
    • Performance improvements in cross-correlation algorithm
    • Other bug and compatibility fixes
