Virtual Audio Cable Audio Repeater Manager

VAC Audio Repeater Manager (VACARM)

In Development

Easily multiplex multiple audio sources. Create, manage, and automate instances of Virtual Audio Cable (VAC) audio repeaters. Compatible with Microsoft Windows 2000 to Windows 11.

Table of Contents

1. Why?

  • Allows for multiplexing of audio streams, of which is not natively supported in Microsoft Windows.
    • If a user wishes to listen to music, a video game, and more, the same audio output must be selected.
    • Windows programs (example: media players, video games, Internet browsers, etc.) may only choose one (1) audio output (and input).
  • For example, effectively treat a video game session like music recording.
  • Turnkey solution, no tedious work of opening or closing instances of VAC audio repeater.

1.1. Use-Case: Software-Defined Multiplexing

Given:

  • one (1) Gaming PC:
    • to play video games.
    • to run VAC Audio Repeater Manager.
    • to capture of the audio/video via a broadcast/stream client.
  • three (3) audio sources:
    • a local microphone.
    • incoming voice chat audio.
    • game audio.
  • Optional: a separate PC to record; one (1) Recording PC:
    • cables and/or adapters to transfer audio (and video) from the Gaming PC to the Recording PC.
    • to capture of the audio/video via a broadcast/stream client.

Allows:

  1. Specify to only listen to two of the three audio sources (incoming voice and game audio) on the Gaming PC.
  2. Record each source as separate audio streams on a (Gaming or separate) PC, for future audio/video editing.
  3. Optional: capture the audio/video via a broadcast/stream client.

1.2. Real-World Equivalent

(Come on, Dave, give me a break) - Unchained, Van Halen

Given:

  • multiple incoming audio sources (instruments and microphones).
  • a time-keeping audio source (a Metronome).
  • the incoming/outgoing communication between audio engineer and band.

Allows:

  • Listen to all sources together, but record separately.
    • Record all channels from music band separately, for optimal future remastering.
    • Allow for future editor(s) to mitigate unnecessary audio sources (time-keeping audio and audio engineer communication) within master recording.

2. Features

  • Load/Save audio stream setup to/from file.
    • Configuration files
    • .bat script files
  • Manage audio stream setup of current or other Windows machine(s).
  • Start/stop audio repeaters from within the application.
  • Easily automate audio stream setup given user-input and/or arguments.

3. Requirements

7.1. Multiplexing

In the scope of this project: one virtual Line-In to one or more physical Line-Out(s).

In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium. Wikipedia
