No more dropouts using the peakmeter ?

[AsusFreak!]

I tested the peakmeter. In the past I had lots of dropouts in the music.
Now it seems to work without them. Maybe this is the reason of the (limited) dualcore support?
Anyone had the same experiences?

@Angry:
If this is true it would be fine adding the peakmeter margins patch to your next build. Thanks.

Maybe. People have reported being able to use more of the Eq with the dualcores as well. What kbps and format were you playing (so someone else might verify/find the limit of useable levels)?

May be related to this commit

ARM optimised memcpy/memmove from glibc. This should give increased performance on all ARM targets, especially iPod 5G

But I am not entirely sure. Maybe you are listening to a song with a lower than normal bitrate?

no, ive noticed it as well. no dropouts listening to music now, and thats with two eq bands enabled.

*Wishes it stopped skipping with increased pitch... All songs sound cool with increased pitch :P*

@druidfire217:
MP3s at VBR192 and VBR256
In the past this was impossible. And I used 2 bands of the graphic eq.

If it's really possible to use the peakmeter I'll make a new WPS and test the battery performance. I think it will decrease the performance but: a real nice feature for the themes...

I would imagine that if you are running 256+2bands of eq and it isnt dropping with peak meters, for most of us this should be verification. Thanks for letting me know.

I've noticed something. In past when you use peakmeters, EQ or music+game, it causes dropouts in the music. But now when you load a lot on the CPU it doesn't cause dropouts in the music but it slows down the machine. I think this is the reason why we can use EQ or peakmeters now.
By the way I don't like this sometimes. Because when I play jewels with music, it is reeealy slow.

It has been discussed before, but what kazimserhan thinks is about right. Sometime near the beginning of december there were modifications made to the way Rockbox gives priority to the various threads (programs) that runs simultaneously. The scheduler now gives priority to the playback engine, so no skip unless you go really wild with the settings, but an UI that could become almost completely unresponsive.

I don't know how much the Kernel-on-cop patch (the famous 'dualcore' build) influences that, though.

[druidfire217]

I decided to test what Paul was talking about. Put on a really intensive EQ (all five bars at least over 1.0), set some music playing, and started playing breakout. The UI would be running really slow, and I would have problems with it recognizing buttons (until it rapidly caught up all at once). But I only had the music drop for about a second every song or two. This was playing a 256kbps at about -30 volume.

paul is right i think what happened is that music playback has priority over plugins and eq , like i used the osciliscope plugin a whileback while playing music, and the plugin ran slow but the music was fine
