Multimic or Siblings how to

@d-healey Wow thanks David. So didactic and clear. Will follow these step by step.
-
@hisefilo I also suggest to check the phase cancellation problem of the sample combinations.
For example, "Kick (close mic) + Room mic" can introduce phase cancellation issue that originate from mic positions / distances. So your kick sound will be very very decent because room and close mic signals cancelled some frequencies of each other.
You can solve this issue with 2 ways
- Adding very gentle delays to dedicated samples. I don't recommend that because it will cause delay in your plugin.
- Or you can apply phase correction and reprocess the samples before building the instrument. You can use Adobe Audition, it has a great bulk sample processor. I think Reaper should have this feature too.
For Phase correction processing; I can suggest "Waves InPhase" (that is paid one), or this free plugin "https://www.forward-audio.de/sampledelay/" ;)

@orange awesome!!!! Working on it. thanks for the advice :)
-
@d-healey I guess eleven mics is to much?
-
@hisefilo Why would it be too much? It always makes drummers proud to be hidden behind a wall of mic...
11 mics? please confess
More seriously, that's a good start, if you recorded 11 mics, I'm sure they all have their utility
-
@ustk LOL !!!
Don't know just experimenting. I want the user to be able to mix, let's say Snare with close mics LR + toms sympathetic resonance + Overhead LRs + Bass drum sympathetic choosing % of each mic to final output. Does this makes any sense for you? (looking for you opinion:)
This is my multimic session right now (driving me crazy)
-
@hisefilo Sure it makes sense! Not only that you can select what bleed you want to keep, but also the fact you can set the amount of bleed per mic! That's a really good idea man
(I wonder how you will achieve this...)Know for bleed, there are 2 schools.
- Those who let the mic without phase alignment
- Those who are aligning very precisely.
I don't want to say one is better than the other, but my personal preference is a modern sound with accurate alignment so the second one. The advantage is double, you can position your mics to have a good sound on each source, so once aligned, everything is even more powerful.
The first generally gives a more old school sound and can be interesting. When you raise the bleed, phase misalignment brings more colour to the sound. But this technique needs a bit more experience, otherwise, the colour turns into a very weak/tiny sound...When I record a drumkit, I like 2 SN, 2 BD, 3-4 Toms, 2 OH L-R, 1 OH SN, 1 Ride, 1 HH, 2-3 Rooms, and if possible 1 Drumkit centre... Yep... That's a lot... I know some people don't like that, but that's me...
-
@ustk Thanks man! Totally newbie on this.
Trying to align phase with https://www.forward-audio.de/sampledelay/ but no luck yet!These are my 9 mics on BD. I guess some of them are useless, but multimic samples should include all of the mics for all of the notes, so I the I should keep the silent also
-
@hisefilo Since it is not a live drumkit but samples, you can choose the bleed you want to propose, like only the OH and the Room, it would be easier to manage. So for each mic you have:
- Proximity Mic
- OH bleed
- Room bleed
and for Room and OH, you only have Room and OH... It's just an example...
I don't know sample delay, I am using Auto ALign from Sound Radix. Is it automatic detection?
For aligning the mic, I ALWAYS use a full take with all drums playing so the detection works better.
It never works either for me on single hits. The plugin needs a "complete overview" of the instrument for several tens of seconds...Your BD seems good, except maybe the inside mic which is a bit "ringgy", but as I don't know the style you aim at...

Auto ALign from Sound Radix
Awesome!!! seems what Im looking for! thanks a ton!
I have the full takes, just cropped BD -
What I mean is not isolated playing but a real drum fill
-
@ustk Sorry but need to ask this! (I think need to take some classes with you) Phase align and delay (due mics distances) are not the same issue? I mean if I can calculate and delay a mic some ms. they will be all in phase, right? Despite the bottom ones that will be -180?
-
Yes and no... Because phase is frequency-dependent, the delay will not be the same for two different frequencies...
180° out of phase doesn't require the same delay at 2 different frequencies...
But yes, in a way that if you re-align two distant mics with the delay corresponding to their relative distance, all the frequencies should be in phase.
But since the audio material in each mic is not the same, nothing is perfect in this world...
-
@ustk I like the yes and no! Quantum answer!!!
I guess will need to bend time and space before recording :)Jokes apart, very clear! Now I get it! Thanks a ton!
-
@hisefilo Yopla! An amateur of quantum mechanic and relativity
-
@hisefilo I just want to add that aligning phase (especially for multiple mics) is not a simple matter, because different setting can work, it is just a matter of taste...
When using Auto Align, you specify the first mic you want to use as a guide in order to align the other. That is said, the most obvious one is not always what works best (namely the BD)
I often use one of the OH as guide, because it has all the other mics equally in it which makes the detection easier,
Sometimes I align the 2 BD mic to the OH, sometimes only one an then the other on the first I just aligned. One rule: no rules...
But to be honest, the most impotant part is to begin with a good microphone choice, placement, and preamps and even more important, a good room! Otherwise phase alignement won't fix anything...Can't help pressing F5 in the forum...
-
@ustk recording was just fine. I guess.
Mics were
- AKG D112.
- Shure Beta 91a.
- Shure Beta 98a/c.
- Shure SM57.
- Shure SM58.
- Shure SM81.
Room was ok also. Not Abbey Road but nice one
-
@ustk dude! take a listen, following your advices. this is brushed drumset played on Hise with my Yamaha 88 controller
-
@hisefilo Man it sounds awesome! Well done buddy
The ride seems to cut here and there, but maybe because it's played realtime on a keyboard...
But the rest is full and aerial at the same time, clean and punchyCan't help pressing F5 in the forum...

You may want to consider this tool as well: http://www.e--j.com/index.php/soundfilesmerger/. I have used it as of recently to merge different mic positions, so I only have to edit once. It merges all of the files into channels.
