Restoring Bass in movies using Bass EQ’ed
« on: July 19, 2019, 07:20 »
Thanks to Jag for sharing this BEQ stuff which I’m still reading. Basically it requires a miniDSP to load the files to work. I’m creating this thread to create awareness and also discussion on some of the butchered titles that may benefit from using BEQ. The first studio that comes to my mind will be Disney titles.

I’ll let Jag and other members to start the ball rolling.

Thanks for this. So good

Just curious, how does this beq thing work? Is there a file for every movie to manual load B4 watching? or the DSP will auto detect the movie's "eq" and deploy target eq?

If the device is capable, it can store multiple presets for different movies as well as for different kind of music. So just load on the fly. It can even do real time adjustment even when the content is playing

This is the BEQ thread in the AVS Forum. You will need a miniDSP.
Could it be said as what the director/movie want you to get in bass? So every movie has its own BEQ settings to be input into your MiniDSP.

Like in the photo

Question is, do we need a flat line to start with & input the data into the Minidsp?

If I'm not wrong, I think we only can add in PEQ for antimode. For the lift & tilt is like a fix placement.  Let me head home later snap some shots on the dual core(before I offload it) & MiniDSP 2x4(non-hd) for anyone reference if needed.

I have some demo material stuff that is Re-encoded and preloaded with BEQ, haven’t really tried it but that’s also available for download

I'm kinda late to this post, but here's my take on BEQ.

BEQ restores deep bass that many studios intentionally remove.... Many studios are now apply heavy filtering to bass <25hz so heavily that it will make high end subs sound like HTiB sub.

How it works is:
1) There are a group of passionate HT enthusiasts that use software to analyse the type of ULF filtering the studios use and reverses that filter.
2) That filter is then loaded into a MiniDSP as a BEQ curve.
3) This BEQ curve works along simultaneously with your room correction EQ and house curve EQ.
4) RCEQ + HCEQ + BEQ...... all 3 EQs work together to :
      a)Room Correction EQ (Dirac Live) will correct for peaks and dips and produce a smooth frequency response. Room acoustic imperfections is responsible in uneven frequency response peaks and dips.
      b) House Curve EQ is that bass boost (mid bass thump or ultra low frequency vibrations) that some like.
      c) BEQ will restore and bring out the lowest ULF and correct for filters that the studios impose on their titles.
5) Once you have applied BEQ, together with capable subwoofers, you will want to watch your movies all over again.

BEQ settings can be automatically uploaded to your minidsp via a HTPC, or you can do it manually based on the settings usually given in the top right corner of the FR charts associated with each movie.

BEQ only works with Minidsp at the moment. Other EQ platforms are not compatible, unless you know what you are doing.

I have been using BEQs for about a year now and I must say that BEQ is a must if you truly want to enjoy your movies and the subwoofer you truly deserve. No more mickey mouse bass just because the studio decides you to have anemic bass.

Hello Jag,

I have some queries hope you can help me.

Do we need to know/understand our subwoofer limitations first? Because if we keep adding alot of filters(PEQ/LS) we would bottleneck our subs? Probably an example some subs unable to go as low as 15hz-20hz.

Apart from MiniDSP, I believe Behringer amp (DIY sub) their software (but limitations on it   is their filters only able to go 20hz if we use peq) I believe lowshelf could help & able to do lower than 20hz

(I'm still out at the moment but rest assured I will post pictures of MiniDSP plugins software, Behringer plugins software & dual core antimode) sorry for the delay guys.
