And when you switch to passthrough audio the volume will be too high since the lower XBMC volume has to be compensated by turning the amp volume louder.

let's try another build since I don't have confidence the right one was built.

No one here is running any external thing like Audio Hijack Pro that can insert AU plugins into the audio chain ?



RE: Eden Audio Quality - User 34959 - 2012-04-24

No change. Had to test using headphones which i don't use normally, but it sounded the same as the other test builds.

I'm using plain OSX with all the updates from Apple Update and XBMC being the only application installed.

RE: Eden Audio Quality - davilla - 2012-04-24

let me see an Audacity capture again, 1st 30 seconds of compressorxbmc.mp3

RE: Eden Audio Quality - User 34959 - 2012-04-24

I can certainly do it, but it has to wait until tomorrow, it's night already.. Which mp3 is that, did you forget the link?

And like i said, i was not using very scientific methods when capturing using builtin speakers and mic, even my own breathing can corrupt the result completely. Macbook's mic seems to be pretty sensitive, picks up noises from far away. I could try capturing the songs using Songflower and Audacity and compare them that way.

use the Macbook's mic, we don't need perfection here.

EDIT: and hold your breath during those 30 seconds Smile

I just tried the new version posted 2h ago, and it's still the same.

The sample is captured with audacity via soundflower. The advanced settings have not changed, the guisettings are here

MacBook Volume was at 100%.

If you want I can try Audio Hijack, just let me know how you want me to capture the song.

I want to see the 1st 10 seconds of compressorxbmc.mp3 from audacity.

Here go for it http://www.2shared.com/audio/xXPV9la_/compressorXBMC_new.html Wink

RE: Eden Audio Quality - davilla - 2012-04-25

Ahh, how am I going to compare that to the plots in post#70 Smile

RE: Eden Audio Quality - davilla - 2012-04-25

Ok, two test builds, that's right a blind test which seems fitting for audio issues. Test both, pick the best one. Note the version (order) does not necessarily mean the later one might be better than former other.

Also, please do not add any advancedsettings.xml tweaks, this introduces too many variables and XBMC should be doing the right thing without them. Fiddling with limiterhold and limiterrelease will only muddy the waters and confuse the results.

RE: Eden Audio Quality - User 34959 - 2012-04-25

Will test in 8 hours, after work.

RE: Eden Audio Quality - basco - 2012-04-25

wow, am i glad i found this post.
i was about to rip my speakers of the wall because thought i had wrecked them.

adding this to advances settings seems to fix my audio quality issues.
i also set headroom to 0.

<advancedsettings>
<audio>
<headroom>0</headroom>
<limiterhold>0</limiterhold>
<limiterrelease>0</limiterrelease>
</audio>
</advancedsettings>
