Voicemeeter

As a virtual mixing console, Voicemeeter makes it possible to interconnect and mix audio streams from many audio devices and applications thanks to the concept of physical inputs/outputs (for audio devices) and virtual inputs/outputs (for applications): USB microphone, DVD players, video games, iTunes, VoIP applications, Digital Audio Workstation (DAW), etc.

Voicemeeter makes it possible to mix multiple audio sources from different devices, such as a USB microphone or line input, with the sound of PC applications, such as a video player.
Voicemeeter Standard offers two physical inputs and one virtual input.
Voicemeeter Banana offers three physical inputs and two virtual ones.
Voicemeeter Potato offers five physical inputs and three virtual ones.

Intellipan, the two-dimensional equalizer of Voicemeeter's physical inputs.

Just like a physical mixing console, Voicemeeter allows you to mix and process the different signals in real time with, in particular, equalizers, compressors and noise gates ("Audibility" button for Voicemeeter Standard), and gain controls materialized by vertical sliders. For the physical inputs, the Intellipan offers equalizers presented in the form of a two-dimensional panel allowing the rapid and almost instinctive correction of the intelligibility of the voice. In addition, Voicemeeter Banana has an advanced independent equalizer on each of the bus outputs.

The generated audio signals can then be sent separately to several physical (speakers, television, Bluetooth ...) or virtual (Skype, Audacity, OBS, Twitch...) playback devices.
Voicemeeter Standard has one physical output and one virtual output.
Voicemeeter Banana has three physical outputs and two virtual outputs.
Voicemeeter Potato has five physical outputs and three virtual outputs.

Voicemeeter thus makes it easy, for example, to change your voice, add music and send all in a conversation via Skype or play 5.1 video games while conversing with your team.

Voicemeeter Banana integrates an audio recorder, in the form of a cassette tape recorder from the 1980s, which allows recording bus inputs or outputs in WAV, AIFF, BWF and MP3 format. It is also an audio player supporting audio files in WAV, AIFF, MP3, M4A, MP4, MOV, AVI, WMA, WMV format,.[5][2]

Voicemeeter can use Windows audio devices with WASAPI (WDM), Kernel streaming or Multimedia Extensions interfaces and it can also manage an ASIO[6] audio device (on output A1). It has one to three virtual inputs/outputs with all interfaces: WASAPI, KS, MME, WaveRT, DirectX as well as ASIO (to connect professional audio software to Voicemeeter). Voicemeeter Banana also offers a virtual ASIO insert driver to connect a VST host application (DAW) and process the various Voicemeeter inputs with software plug-in or any professional audio applications.

Voicemeeter also comes with recording and playback audio drivers (giving the virtual inputs / outputs). Once these have been configured as default devices, they allow you to perform all previously mentioned tasks while avoiding conflicts between audio devices.

The VBAN protocol makes it possible to send / receive uncompressed audio streams over a local area network[7] and thus to interconnect computers without having to use audio cables.

The control of the main parameters by a MIDI control surface allows managing all the sound of the computer with a dedicated controller (Korg NanoKontrol for example).

Voicemeeter is installed with MacroButton, which allows you to create complex functions to act on one or more of the settings of Voicemeeter[7] with a keyboard key (keyboard shortcut), a MIDI code, a threshold on an incoming signal (trigger) or an Xbox controller button (XInput).[8] It is thus possible to change the Voicemeeter configuration with a single click and instantly adapt it to the different uses that one makes of it.

Voicemeeter can be considered as a system audio component that can be used by any application. An API called VoicemeeterRemote API[7] allows read and write actions on Voicemeeter parameters and thus control Voicemeeter from a program to use it as an audio service or as a virtual sound card. A program can thus set up signal processing callbacks to process the sound in Voicemeeter.[9] Any programming language can be used.
