XXHighEnd-09-z7.4 Stop issue

Thank you very much Johan.
You were just ahead of me ...

Leaving the fade-out step at 3 and with the settings in my signature, the new Engine3 works well. Small ticks at volume changes and sometimes a small tick at the beginning of a playlist but that's about it.

Hi Brian,

As we are in the same league on low SFS and net buffer size, I would appreciate your sharing of experience at the stop of track.

With your current set up, I wonder if you had any inaudible "plob" at the "stop" or "next" of the track at all. You can use DC volt meter to measure this strong LF AC pulse (approx +/- 1 volt depending on digital attenuation level) at the binding posts. Alternatively, watch the excursion of the woofer to see if it traveled so much.

Thanks,
Praphan

Below there's a version of the sound engine that won't go into the loop. BUT, it also doesn't go into any second loop of buffer playing.

Let me know what happens ...

Hi Peter,

The loop problem is completely solved.

In addition, this version of XXEngine3 does give me a better solution to minimize the PLOP at the stop of the track. It did turn scary PLOP to small plob at the stop or changing track.  However, this can only be achieved with very narrow setting range ie SFS at 2 and only 2 and net buffer of 14(or 15)x1x 4096. Tick by changing digital volume can be indirectly solved by using normalized volume. To minimize tick when changing volume, SFS has to be 60 and this is not good since it will bring back strong PLOP at STOP.

So far so good for me. Thanks so much.

Hi Praphan, its too early here to test right now, but as I recall, I wasn't getting any ticks or plops at stop or at changing tracks (Alt N) in the middle of one playing. Also I didn't test any other SFS. Will play around with different settings this evening.

Thanks a lot Brian. No hurry. I still have acceptable plop at stop and changing track. If you don't then I will try to leverage from your experience.

My bad. Yes I have sometimes two small ticks, and sometimes the last sample or samples briefly repeat, when I stop or change tracks. They are not loud or dangerous soundin. Setting the SFS to 60 and I get the same results as you as well.

[praphan]

Brian thanks,

As for me the plop at SFS 60 is larger. So I settle at SFS of 2 which results in a more favorable SQ in my system.

In  my system voices are too flat with a SFS of 60. They are more harmonic or dimensional with a SFS of 2: previous harshness with a really low SFS has been replaced by this more complex, "realistic"  sound. This has been the case for me since the initial release of 9Z7. Then again maybe I've become addicted to a kind of distortion, but I sure do like it.
