[Tactile] tutorial Simhub + Equalizer APO + Peace (WIP)

Hi!

As there are few (none in fact) ressources about how setting up this specific configuration, I'll post my progress here and share the results :)

As a start, I stumble on this exact problem:
The biggest problem I encountered in using software DSP packages was trying to figure out how to route the signal from SimHub to the software and then out over an audio card.

Maybe I'll ask some help to configure APO if I don't succeed... @ScreaminBejesus @Ormy

I think I figured it out, see below...

PS: about DSP ParametricEqualization (hardware or software), see there: [tactile] Upgrading my tactile setup with DSP

PS: of course, APO can be applied also on Game audio (but not as a starter ;) )

- So the game send telemetry data to Simhub
- Simhub convert this into audio signal to sound card channels
- APO And Peace make their magic on these channels (inside/above/after the soundcard?)

My problem was windows channels and Simhub channels and APO channels...

1/ Windows
Configuring Windows 10 surround is unobvious (Am I the only one having the feeling to go around in circles when dealing wtih Windows audio parameters?)

Here's a cmd shortcut:
- Win key + mmsys.cpl
- Open Command window: mmsys.cpl
- Or create a .bat file with
control.exe C:\Windows\System32\mmsys.cpl

Select the appropriate device, then click [Configure]:
how many speakers, ...

Clicking on the speaker should shake your bass shakers!

Advanced audio settings: assign the right sound card to the right application
Start from Audio menu

and switch to Advanced sound Options

2/ Simhub
Wotever:" Sound cards Color code mostly refers to 5.1 setup, in the case of Simhub you will be using channels in raw order following the current configuration of the sound card (stereo, quadriphonic, 5.1 .... 71 ...). Since each channel will be used as a classic output, color code is meaningless here.
Simply use the "test channel" button to know which output is active depending of your setup."

3/ APO + Peace
During APO installation, you'll be prompted to install "devices":
Playback devices: select the tactile sound card

Capture Devices:
none are needed

You can start with one and relaunch later the configurator.exe if you need another try
C:\Program Files\EqualizerAPO\Configurator.exe

Create speaker configurations on which you'll apply the PEQ.
I started with Buttkicker
then a second with Left+Rigt together
As a matter of fact, 1 of my bass shakers is weaker than the other but it'll probably be easier to tweak the level in Simhub and keep one single setup for 2 bass shakers...

To do that, create a filter for "buttkicker" (plus button)
I tried with Center, Subwoofer and Center rear.
Name accordingly the speaker configuration ;)

First objective: finding the correspondance

Prerequisite: when clicking Simhub test channel, your bass shaker is shaking.

flatten the EQ and use the down arrow to lower the gain on every frequencies (say -6 dB)

With Simhub, click on test: vibration should be significantly lower.

With Peace, edit the Speaker (square button) and uncheck some. Retest until you found the speaker you looked for.

With Microsoft audio configuration, the sound is also lower.

I'm looking for an easy way to do a frequency sweep on all the transducers? without plugging and un plugging cables...

not found :(
http://sox.sourceforge.net/sox.html ??

Here is what I'm doing:
- Firefox on webpage https://www.szynalski.com/tone-generator/
- Windows Advancedd audio Options: assign tactile sound card to Firefox
- Plug the audio cable (of the transducer being tested) into "Front" plug of the amp as Firefox tone generator send only sound to Front.
- note values
- try to erase the bangings with PEQ. Drawbacks: with APO Peace, you have to modify the Front Speaker profile...

first conclusions:
It's hard to define a filter that specifically lower the power on few frequencies without muting it completely...

I need to determine an approach on volume levels, gains before applying PEQ.
windows:
mixer volume
audio configuration ?

games:
cf mixer volume
need to adapt per car model?

Simhub:
gain on output settings
gain on each effects
need to adapt per car model?

DSP (APO or hardware):
gain

Amplifier:
physical gain button

in my search of a simple tools to cast a tone to a specific channel (to prevent plugging and unplugging cables), I've found this.
Here's the source code to a test application that plays a different tone on every output channel in 6 or 8 channels.

But I cannot compile the sources in Visual Studio. Somebody could help please?
(renamme the file .txt into .zip)

While still working on single devices at a time, but looking ahead to multi-channel,
here is a technique for directing RoomEQ Wizard (REW) output among individual channels:

Having used REW for years on Macs, I am only now learning audio limitations on Windows.
For example, much other free Windows audio software, including REW,
rarely support other than main left and right channels for any audio interface. Consequently,
since SimHub ShakeIt is not so limited, leaving front L+R channels unassigned in SimHub
minimizes disruptions when temporarily re-routing one or two transducers at a time
to use those L+R channels with other software.
By default, REW uses left channel for timing reference while analyzing on the right.
