ShakeIt V3 Bass Shakers Audio Output Configuration

Wotever edited this page Nov 2, 2023 · 12 revisions

Introduction

ShakeIt allows you to use any audio outputs required, up to 8 channels each, these outputs (sound cards) must be dedicated to bass shakers to avoid any conflicts between regular sound (game sounds) and generated frequencies (dedicated to shakers).

The maximum number of channels supported depends on your sound card and/or wiring :

  • Digital outputs using optical output can't go above 2 channels when using PCM (ShakeId sound generation is based on PCM)

Wiring

Basic principle schematics :

Make sure to refer to the component's datasheets (shakers and amplifiers) to make sure all parts fit:

  • Enough amplifier power
  • Matching amplifier and shakers power
  • Matching amplifier and shakers impedance (ohms), matching impedance can be achieved by putting shakers in series or parallel if required)

Enabling outputs and configuring your sound card(s)

In the Shake It plugin go on "sound output" and enable the sound cards used for your transducers :

When enabled the number of channels effectively configured on the sound card will show :

If this number does not fit your needs you must configure it in windows audio settings and/or your sound card drivers.

A direct shortcut to windows audio settings is available in ShakeIt

Available settings may vary but you need to choose according to the number of channels you want to use :

  • Stereo: 2 channels
  • Quadriphonic: 4 channels
  • 5.1: 6 channels
  • 7.1: 8 channels

Automatic sound interface reset

A short time after the game is connected or disconnected SimHub will reset all the connected audio interface, this is intended to workaround VR headsets changing audio settings on the fly and breaking secondary audio outputs. You can change these settings (delay and behaviour) from the advanced output options dialog (Starting from Simhub 7.4.3) :

Selecting the "channel mode"

For each sound card you must choose which audio mode you will use:

There is 4 channels mode available :

  • Mono: left and right will be fed with all the effects,
    • Perfect for a single shaker configuration or a not "left/right" basic setup
  • Stereo: all effects will be spread to the left and/or right depending on the effect
    • This is the basic configuration for a basic 2 channels setup spread left and right of your rig.
  • 4 Channels: all effects will be spread to the 4 corners of the rig using 4 channels
    • Note: Depending on the game and provided telemetry some effects may not be located perfectly on each corner, this is a limitation of the games.
  • Custom channel map: allows you to configure effect per effect, location per location which channel must be used
    • Ideal for any other setup, combinations are virtually infinite

Configuring the Custom channel map mode

Choosing channels

Simply enable or disable each effect on the wanted channel :

NB: For clarity only affects added to the current profile are available for configuration

Fine effects balance

You can balance each effect on each channel by enabling "Show per effect gain":

Troubleshoot channels output and or amplifier

If you have troubles locating the correct output or getting a proper output :

  • Test each output plug using headphones and "test now" buttons inside SimHub, it's the easiest, and fastest way to ensure the sound is outputting
  • Make sure your amplifier is correctly plugged and working by playing some musing using your phone for instance.
  • Make sure your sound card does not require to configure channels on both windows and the driver control panel (refer to your sound card manual)

Troubleshoot sound card issues

  • Drivers : bad/missing drivers installed, simhub uses waspi, an advanced api for reducing latency even if windows can send a test sound it does not necessarily means waspi is working, uninstalling properly the driver and reinstalling it helps in such case.
  • USB issues/power/bandwidth : in case of USB sound card, it can be affected by cable/bandwidth/usb issues (once again testing with windows is not determinant as it does not uses every channels at once) :
    • Try with another usb cable
    • Try to change the usb port (ideally remove any usb hub), if it's already connected to the motherboard try to move it away of any high bandwidth devices (webcams, mics etc ...)
  • Defective USB card, it sometimes happens, even more on cheap USB integrated amplifiers. This time testing the sound card with windows would give some clues
  • Defective power transformer : in the case of an amp with integrated sound card, if the amp transformer is defective it can break usb communication as soon as the sound card gets initialized.
  • Other devices bad driver : sometimes some audio soundcard/device (virtual sound card ...) comes with bad drivers and will affect other devices which were working previously, try to disable your sound cards one by one (run mmsys cpl and then you can right click on each one to disable it)
  • Exclusive mode : One of the most common issue, if you use some virtual mixers (IE Voicemeeter) software they can take the sound card in exclusive mode and prevent any direct connection. Make sure your sound card is free from any of these usages. you can also through mmsys.cpl disable exclusive mode : in your device properties advanced statistics tab uncheck allow exclusive usage.
  • Audio enhancements : once gain in mmsys.cpl, in your devices properties make sure that any enhancements are disabled.
  • Inappropriate Default audio quality : once again through mmsys.cpl , in your device properties advanced statistics tab make sure the quality is set to 16bits 48000hz (DVD quality)
