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

https://www.avsforum.com/forum/113-subwoofers-bass-transducers/2995212-bass-eq-filtered-movies-105.html#/topics/2995212?page=10

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'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.

Yes. Lyngdorf is currently a one stop solution to all this. I'm still glad I went to this. Thank you for your guidance

Noob question here.

Using behringer DSP...So if I already calibrated in such a way that I have the curve already with all those peq settings in behringer filters band, does it mean that I have to add or minis using that corner recommended chart to achieve better experience?

What I'm trying to express my thoughts is, example I need to +2db at freq 50hz so that I have flat house curve for bass due to room modes.. then, the chart says example...need to -3db at 50hz to have better experience, so I have to adjust my house curve to -1db at 50hz? Not sure if you guys get what I'm trying to say

My understanding is if your sub is not able to go low then BEQ will not be beneficial. Example: I have dual SW12 and they don't dig low below 20hz so no point for me to apply BEQ to my miniDSP.

Yup, have to see how low it was tuned and if there is any hardware limitations... But there are "hacks" which can trick the hardware to go lower one way or another that I saw before (should be AVS I think)

Some demo clips with BEQ done by 'aron7awol' the guy that did most of the BEQ filter on the BEQ thread on avsforum. Play those clips with caution,can't believe they BEQed Olympus Has Fallen Washington Monument collapsed scene,there's 20+ seconds pure 20hz content @high spl within this scene,1 of the most demanding 20hz scene ever mixed even without BEQ.
'These are reduced in level to prevent clipping. The filenames will tell you by how much. You should increase your MV by that amount if you want it to play at a normal level.
They each contain two tracks, with and without BassEQ, so that you can switch back and forth while playing to compare.'
This is how he make those clips & what MV to playback.

Thanks for sharing. Appreciated. Personally I felt those titles are already very good with normal listening. The ones that truly can benefit are those Disney Marvel titles imo...are there any of those with BEQ optimised?

For those interested on how to do a remux...here's a detailed step-by-step guide.

Reading material - Primer (Impt!): https://www.avsforum.com/forum/113-subwoofers-bass-transducers/2995212-bass-eq-filtered-movies.html#post56610164

Download the BEQDesigner app here: https://beqdesigner.readthedocs.io/en/latest/ to create and upload the BEQ filters

For those who have the MiniDSP, follow these steps to upload the BEQ filters for the selected movies: https://github.com/bmiller/miniDSPBEQ

Save or bookmarked this Github for the latest updates on the list of updated BEQ'ed movies from the creator: https://github.com/bmiller/miniDSPBEQ/tree/master/Movie%20BEQs

Enjoy!


WARNING!
Remember these are content independent. This is NOT a set-once-and-forget-it. So do be careful when playback as you never know how your subwoofer(s) can handle the increased ULF. So try it out at a safe MV (Master Volume).

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.

Thanks Jag for sharing! All nicely summarised

Lol Mickey Mouse bass indeed from all the Disney movies 🤣

Yup agree. Call "atmouse" effect.
