What VB-Cable enables in your live shows

VB-Cable creates a software audio bridge between a Windows application and your browser, with no mixer UI: ideal for direct routing.

Music from an app

Send Spotify, Deezer, or VLC to CABLE Input; Gniark Live reads CABLE Output.

Jingle or soundtrack

Route a dedicated player to the virtual cable while speaking on another mic (if the browser allows).

Targeted app audio

One application at a time to the cable, without capturing all of Windows.

Voicemeeter foundation

VB-Cable is the driver Voicemeeter uses for VAIO virtual inputs/outputs.

Prerequisites

  • Windows 7 through 11 (32 or 64 bit, Arm64 on recent builds)
  • Administrator rights to install the driver
  • Up-to-date Chrome, Firefox, or Edge for Gniark Live

Install VB-Cable

  1. 1Download the pack from vb-audio.com/Cable (VBCABLE_Driver_Pack45 or newer).
  2. 2Extract the archive and run VBCABLE_Setup_x64.exe (or x86) as administrator.
  3. 3Restart Windows after installation (required by VB-Audio).
  4. 4Open Settings → System → Sound: you should see CABLE Input under output and CABLE Output under input.
  5. 5Optional: run VBCABLE_ControlPanel.exe (included) to verify levels on CABLE Input.

Understanding CABLE Input and CABLE Output

Flow is one-way: Application → CABLE Input → (virtual cable) → CABLE Output → Gniark Live. Do not swap the names: Input = Windows playback, Output = Windows recording.

Configure VB-Cable for a live show

Scenario: stream music from an application

  1. 1In your player (Spotify, VLC, foobar2000…), open audio settings and choose CABLE Input (VB-Audio Virtual Cable) as the output device.
  2. 2Start playback: the VB-Cable control panel (or Windows meters) should move on CABLE Input.
  3. 3In Gniark Live, select CABLE Output (VB-Audio Virtual Cable) as the microphone.
  4. 4Application audio is now streamed to the live.

Monitoring: hear audio locally

To listen to what goes to the live, enable Listen to this device on CABLE Output (Sound Settings → Input → CABLE Output → Properties). Use headphones so your physical mic does not pick up speakers.

Audio format

By default VB-Cable is stereo 48 kHz on Windows 10/11. If an app forces another format, open advanced properties for CABLE Input/Output to align sample rate and channels.

Select VB-Cable in Gniark Live

  1. 1First configure your app output to CABLE Input and verify signal.
  2. 2Open Gniark Live and start streaming.
  3. 3Allow microphone access, then choose CABLE Output (VB-Audio Virtual Cable).
  4. 4Validate with a viewer or second browser before going public.
Voice + music

Gniark Live selects only one microphone device. To mix voice and music in the same stream, use Voicemeeter Banana and select Voicemeeter Output in the browser.

Frequently asked questions

Is VB-Cable free?

VB-Cable is donationware from VB-Audio: free download, donation encouraged. Voicemeeter (same vendor) remains the solution for mixing multiple sources.

What is the difference between CABLE Input and CABLE Output?

CABLE Input is the playback device: that is where you send audio from Spotify, VLC, etc. CABLE Output is the recording device: that is what the browser uses as a microphone in Gniark Live.

Can I mix voice and music with VB-Cable alone?

VB-Cable carries a single stereo stream. To combine mic + application + jingles, use Voicemeeter Banana, which integrates VB-Cable and a full mixer.

Does VB-Cable work on Windows 11?

Yes, pack VBCABLE_Driver_Pack45 (2024) supports Windows XP through 11, 32/64 bit and Arm64.

CABLE Output does not appear in the browser.

Restart Windows after installation, verify CABLE Output is enabled in Settings → Sound → Input, then restart the browser.

VB-Cable or Voicemeeter Banana?

VB-Cable fits a single software source (music, jingle). Voicemeeter Banana fits voice + music + monitoring with faders and B1 bus.
