I will definitely send an problem report. Thanks for the link.
Im using foobar with addons WASAPI and ASIO. WASAPI Exclusive and ASIO are basically serves the same thing which is bit-perfect playback. It allows the sound card to exclusively communicate with the player w/o any windows mixer etc. So that you get pure audio. Of course in sound card settings you need to disable any audio changing options like EQ and so. Another thing is to change sample rate of the card, ASIO does that automatically for my Xtreme Music card. In WASAPI I have to do that by myself.
And remember you wont get any sound from Youtube or any other sound source if you use WASAPI exclusive, you'll hear only the music. And in windows sound settings serve as WASAPI shared, that is if you change sample rate in there lets say 192kHz and game you're playing is at 48kHz (generally it is) so windows will upsample your game sounds to 192kHz by its software and its not good.
Therefore I dont ever use EQ or any DSP etc. etc.
We have to have a bass management, period. And it includes bass re-direction and its cut-off frequency. I have these setting in my XtremeMusic, Im using satellite speakers (Creative G500) therefore I have a subwoofer so in windows settings I select (not large/full range) small speakers and in bass management I enable bass redirection and set cut-off to 120Hz.
The idea behind it is, satellite speakers dont have full range, they need a subwoofer. So anyone has these type of system has to do above process. Because in movies, games, musics, they all have lower frequencies in front rear left right channels BUT satellite speakers are not capable of delivering these frequencies so they have to be redirected to subwoofer with a cut off freqeuncy that is mostly 120Hz (subwoofers give frequencies up to 120Hz basically). THX recommends 80Hz though, but it sounds too bassy in my setup G500 which is THX certified lol.
So subwoofer channel consists two things LFE + Redirected bass. LFE is the dedicated lower frequencies just for the subwoofer only.
