I doubt that the volume leveling value for the desktop client is used by the library, though I can't be sure. Sometimes you will get a 160k file rather than 320 - you can often see this if you have logging for the helper app set to debug. Other than setting a preference for 320k, there are no api calls to influence sound quality. -- Triode Triode's Profile: http://forums.slimdevices.com/member.php?userid=17 View this thread: http://forums.slimdevices.com/showthread.php?t=82484 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Spotify sound quality
I too have the impression that the soundquality of 320kbs OGG Spotify isn't that great. I even think the few 256kbps AAC files I bought from iTunes sound better. I'm not really an audiophile, but like good quality. My music collection has been ripped to .flac files and think it's hard to tell the difference between 256kbps AAC files / 320kbps MP3 files lossless flac files. However when I switch from Spotify to my own library I always think it sounds better. -- verypsb 1x Boom, 1x Classic, 2x Duet, 1x Touch verypsb's Profile: http://forums.slimdevices.com/member.php?userid=17295 View this thread: http://forums.slimdevices.com/showthread.php?t=82484 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Spotify sound quality
Bitrate is just one quality parameter. Encoding quality is just as important. Are you sure Spotify does nothing to the mastering like dynamic compression as radio stations do them? -- pippin --- see iPeng, the Squeezebox iPhone remote, at penguinlovesmusic.com pippin's Profile: http://forums.slimdevices.com/member.php?userid=13777 View this thread: http://forums.slimdevices.com/showthread.php?t=82484 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

In the good old LP days I had some for radio only maxi singles . FM stations grind their stuff thru these wile devices optimod multiband compressors http://www.orban.com/products/radio/fm/feature_comp/ There is simply no way to tell if you did not encode decode the files yourself from the same source . When the difference is very big, the chances are that it's not the same mix you are hearing btw do spotify provide rg tags ? -- Mnyb Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 and assorted amps SiriuS, Classe' Primare and Dynadio speakers, Contour 4 Contour Center, and Contour 1.3SE for the rear ch.

Re: [SlimDevices: Audiophiles] Spotify sound quality
I haven't used spotify, but it should be nearly impossible to tell the difference between 320 kbps lossy and lossless. I think it might be possible, but only for people that know exactly what compression artifacts to listen for. If you check out hydrogenaudio.com, there have been some extensive tests done on audibility at various compression levels (by some of the people that designed the lossy codecs in the first place). At least for LAME MP3 128 and below is very easy, 192 is possible, 256 is very hard, and 320 would require very, very careful listening if it's possible at all. So if there's really a significant difference, something is wrong somewhere. The first thing to do is try it blind, making sure volume levels are matched. If you can still tell them apart, it's time to take a look and make sure the stream really is 320, that there's no nasty transcoding going on, etc. -- opaqueice opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=82484 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Spotify sound quality
Some older Spotify tracks are still streamed at 160 kbps. That may be some of your problem. It's the newer ones that are 320 kbps. For a 320 kbps track, you should be hearing a small difference on a revealing system. If it's very large, then I would suspect a fault. -- HectorHughMunro HectorHughMunro's Profile: http://forums.slimdevices.com/member.php?userid=16514 View this thread: http://forums.slimdevices.com/showthread.php?t=82484 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
