A; To set the panels above your playlist, go to : Preferences,Display,columns UI, "Other" tab, use :list all toolbars, then add the panels/toolbars/visualiszations that you want to use (near the top of your screen, not in the sidebar area). Organize them as you want them to be displayed. And finally use the minimum height values of the corresponding panels. As it is not an usual way to use the toolbar, you may have some crappy things. Use it knowing that it may create some dislaying problems. Musicmusic may fix this into the next version of UI columns.

Q: Is the sound really better with foobar?
A. As the author of foobar says himself, foobar doesn't have a better sound than the other players like winamp and Co. From a theorical point of vue, the sound from foobar2000 is not different from the sound given by other softwares, a player isn't able to improve the sound incredibly, (it can only alter them if not correctly setted). Your hardware is much more important (audio card, speakers, headphones, even cables..), as is the audio source (audio CD, lossless encoding, quality of the lossy encoding process). The software part is only secondary. And even if DSP or other sound modifiers are used, it only widens the gap between the source and the listening, which may prove to only degrade the sound itself.

Q: Foobar always takes between 5min and several hours to open all my files in the same playlist, is there a way to reduce this time?

A. Of course no, just try to visit these links: Foobar Gallery, Everyone post your foobar, the UI forum, Navigator-Suite Feedback, questions, bug-reports or just chatting, Azrael, Feedback, bug reporting and more. OLiGhT, foobar 2000 formatting

Q: I have updated my tags but foobar still shows the old tags, how to mend this?
A. Foobar only adds the info in the database if it is enabled, so you have to update the info in it, select the concerned files, right click, database, reload info from files.

Q: I use the volume control toolbar but it doesn't work, what's the problem?
A. I think that you use kernel streaming or ASIO. Change your outpout, those two output modes are not consistent with the volume control toolbar.

Q: There is always a latency time between my DSP changes and their effect, it's really annoying.
A. Just try to reduce the buffer length of your output mode. But do not put it to the minimum length, 300ms should be already good (more if you are using several DSP)

Q: Which DSP should I use?
A. It highly depends on you and your use. For a description of the DSP and their effects, just see here: DSP.
