Thanks so much for this, it helped me a lot.Simple Remux BassEQ Tutorial
This tutorial does not go into every detail. You may have to experiment in BEQ Designer to figure out exactly what each step entails. This will apply a simple BEQ with a single set of filters on all channels.
1. Extract Audio - Decimate but do not Mix to Mono. This will keep all of the independent channels.
2. Add Signals. You should now see a signal for each channel.
3. Link Signals - Make one the master and make all of the rest slaves. Now if you add filters to the master, all of the signals will get them.
4. Add Filters to the master signal. You should see the filters take effect on all channels on the PvA graph.
5. Check Headroom - Click the up arrow below the PvA graph. This will bring up the waveform graph below. Check the "Filtered?" checkbox. Now select each signal and make note of the headroom shown. One or more of the signals may show negative headroom. The negative gain you choose to add should be based on the worst case, so make note of which signal had the least headroom (or the largest negative headroom). Add a negative gain filter to the same master signal above to increase headroom so that it is no longer negative on any of the channels.
6. Remux - If you followed all of these steps starting with extraction, the signals should map to the filters automatically.
This tutorial was meant to be quick and simple. It won't answer every question for someone first starting with BEQ Designer, but it at least gives you the guidelines to follow as you work your way through learning how the app works.
1. You will lose audio objects in Atmos/DTS:X mixes.
2. Many mixes already have channels with little or no headroom without any filters added, so don't be alarmed by that.
3. The negative gain added in step 5 will reduce the overall volume, so you will need to raise your MV by the same amount in order to playback the remux at the original volume.
4. If you check "Include Original Audio" you can also specify a gain to apply to it. You will want to match the gain you used in step 5, if you want to be able to switch between the audio tracks to compare.
5. If you check "Compress Audio?" when remuxing, it will encode the audio as FLAC instead of uncompressed PCM.
6. If you want to do per-channel BEQ rather than applying the same filters to all channels, simply skip the Link Signals step and you can apply different filters to each channel.
I almost have my first BEQ'd movie!
There's one part I'm confused on though, which is step 5. I went through each channel and did see Headroom being negative, with -7.00 being the highest on the center for Ford v Ferrari.
I'm not sure where I'm suppoosed to change the negative gain though? I've reviewed the docs but It's still not clear.
I do see a section which shows "LS,LS,PEQ", and ahows the gain, but not sure if this is the right place?
thanks again for any clues!
