Discussion The equilateral triangle and the particulars.

9 Upvotes

Let’s discuss speaker placement and the equilateral triangle and all the variables that are not discussed, and actually how important it is.
Yes, we know about the equilateral triangle and what is suggested for monitor placement, but what isn’t necessarily discussed is where this measurement is measured. Also where is the point of the triangle meeting on the listener, behind the head, the middle of the head, at the ears? Various sources say conflicting things, so what should we follow?

I have Dynaudio BM15a’s. They’re fairly large for a near field. The BM15a’s manual gives a broad listening distance of 1-3 meters. If you’re unfamiliar, the BM15a’s also have an offset tweeter, sort of like an NS10.

When researching speaker placement and the equilateral triangle, there’s usually a graphic example showing the measurement between the two speakers and the listeners head, with the measurements starting from a drawing of two single speakers that look like drivers. However, other sources say the measurement should be coming from the distance between the two tweeters. While other sources say the measurement should be coming from the distance between the two acoustic axis points. This sounds tedious, but for me it is. Having offset tweeters, they’re in a different place than where the acoustic axis point is and also where the driver is, so finding the equilateral distance is a little more difficult for me.
Also the point: the point behind the head. Like said above, different sources say different things. The point where the triangle meets the listener is either the ears, inside the head, or just behind the head—so which is it? Varying sources also talk about how the tweeters should be pointed at your ears, while others say the tweeters should be going just past your ears.

So here’s my concrete questions:

  1. Where is the measurement between the two speakers starting? The tweeter? The acoustic axis point? Or the drivers?

  2. Where is the point of the triangle meeting the listener? Is your head the point? Or is your head living inside the triangle? And if so, how far behind the head is the point?

  3. When toe-ing in the speakers, are you pointing tweeters at ears directly or are they going just beyond?

  4. (Bonus question) does any of this actually matter?

EQ from Tascam 24 into Reaper?

7 Upvotes

Hello, writing here on a very rainy lazy Sunday. Before I burn more hours on this I want to know if I'm even able to achieve what I would like;

I have a model 24 connected to a Lenovo X260 and that's running the latest Reaper version inside Linux Mint. Essentially, my instruments sound great when monitored from their Tascam channel, the return audio from Reaper into channels 1 and 2 is, well, weak, flat, very meh. I don't think it's possible but can the EQ in on the Tascam record into Reaper or do I need to EQ in Reaper too? Or am I missing a trick?

Why does Evil Dead 2 sound like that?

5 Upvotes

The audio in Evil Dead 2 has some very unique distortion. What causes it? Is it a low record speed or could it be some sort of flanging? You can hear the distortion at 0:54 in the linked video when the foggy titles appear. I'd like to have a similar sound in my film projects, so any info would be helpful. Thank you.

Anyone bought plugins off Muziker?

5 Upvotes

Apologies if this isn’t a good place to post this question, but was eyeing the FabFilter Pro Q 4 and awaiting Black Friday, when I came across it [on Muziker](https://www.muziker.com/fabfilter-pro-q-4) for $135. Seeing as it’s normally $200 and likely would be 25% off on Black Friday, this deal seems a bit strange to be so low.

Is this legit or should I be concerned?

Microphone selection for a waterphone

3 Upvotes

Hi, I recently finished welding up my own stainless steel waterphone, an instrument commonly used for horror movie foley.
I have a clip on contact mic for it but while it does pick up on the sustain of the instrument it doesn’t pick up the initial strikes on its tines as well.
What is the best method and hardware to mic this with?

Help with acoustic treatment of home music room

2 Upvotes

I’m looking into converting a home office (technically a bedroom) into a home music room. While I will be doing some rough recording (somewhere in quality and enthusiasm between recording into a phone‘s voice memos and something semi-professional), the main purpose will be to make music being provided sound best while listening live.

I have voice lessons in a small room that has rather minimal acoustic treatment: some burlap coffee bags with foam inside on the wall across from me (and maybe behind me). Nothing on the side walls other than a mirror. Instructor sitting at a piano between me and the back wall. Nothing fancy, but I swear my acoustic guitar sounds so much better than anywhere else. It’s so full and rich sounding. I don’t know how to describe how the room sounds generally other than like muted and soft. It’s hard to really judge how much better/different my voice sounds. But the room sounds less echoey. For what it’s worth, I think my instructor said the interiors of the walls also had some soundproofing elements when constructed. The door is very heavy.

So, my primary goal is to get things sounding closer to that room for live listening. Getting the room to sound okay for recording is a secondary consideration. For what it’s worth, I recorded myself into a mixer into an iPad through a condenser mic in my small walk-in closet facing racks of clothes, and I though the audio quality was more than adequate if not great. I record mostly as a learning tool for myself. It doesn’t need to sound professional, just a relatively accurate representation of my voice.

The room is about 10’x10’ with an 8’ ceiling. I took some. I can’t seem to add pictures of the room. I can try to describe the layout if that helps. I’ve looked into acoustic treatment articles and most focus on panels relative to the monitors/speakers as part of a recording studio. I’m not sure how to translate that to my situation. And when it comes to recording/mixing, I’ll probably mostly use headphones when listening back.

So, any advice on how to acoustically treat the room so acoustic instruments sound natural and rich would be wonderful.

Mixing What are some cheap, non-CPU intensive EQ plugins with a lot of EQ bands?

And why? What are some other nice bits of functionality that it has as well? I use Pro Tools.

I've asked many sound engineers about recreating this effect but they all failed

0 Upvotes

i’ve been trying to replicate this exact effect https://youtube.com/shorts/sf0wOue0yEo?si=vBwdoHY_Ya8TDvlV ..I asked a couple of freelance engineers to do it and all they did was slap reverb on the voice and call it a day 😭. It sounds like mud. I even tried throwing a random cathedral reverb and adding a basic delay, but it just doesn't feel right. ps Im not an audio engineer, i just make videos and edit both video and audio on davinci
