While Android lacks a direct, one-click equivalent to desktop virtual audio cables, tools like AudioRelay and VBAN Receptor enable internal audio routing on Android 10 and above. These applications, along with dedicated tools like Internal Audio Recorder, allow users to capture or stream app audio by leveraging internal capture APIs.

The concept of a "Virtual Audio Cable" (VAC) is a staple for Windows power users, allowing them to route audio from one app to another seamlessly. On Android, however, the landscape is different due to the operating system's strict security and sandboxing, which prevents apps from easily intercepting each other's audio. Despite these hurdles, there are several powerful methods to achieve virtual audio routing on Android for streaming, recording, or music production. 1. Understanding the Android Audio Sandbox Unlike Windows, where a kernel-level driver can create "Virtual Cables" like Line 1 or Line 2 for any app to use, Android isolates app audio. To route audio between apps, you typically need one of the following: A "Bridge" Protocol: Using a standard like VBAN to send audio over a local network. A Content-Aware App: Using specialized DAWs (Digital Audio Workstations) that support internal routing. A PC Intermediary: Routing Android audio through a computer to use classic VAC software. 2. Best Solutions for Virtual Audio on Android VBAN Receptor by VB-Audio Created by the same developers behind the famous VB-Audio Virtual Cable and Voicemeeter , VBAN Receptor is the closest official mobile equivalent. How it works: It uses the VBAN protocol to receive high-quality audio streams over Wi-Fi. Best For: Sending audio from your PC to your phone (or vice-versa) without quality loss. Find it here: You can download the VBAN Receptor Lite for free on the Google Play Store. AudioRoute (for Musicians) For those in music production, Audioroute is an open-source library that allows different Android music apps to exchange audio and MIDI data. How it works: It acts as a virtual patch bay between compatible apps like synths and effects processors. Best For: Live performance and mobile recording setups. AudioRelay & SoundWire These apps are primarily used to stream PC audio to Android, essentially making your phone a "Virtual Speaker". How it works: You install a server on your PC and the client on your phone. Usage Tip: By using AudioRelay in combination with a Windows Virtual Audio Cable , you can route specific PC apps (like Discord or Spotify) directly to your Android device. 3. How to Set Up a Virtual Audio Bridge (Android to PC) If you need to send your Android audio into a PC application like Zoom or OBS, follow this common "Virtual Cable" workflow: VB-Audio Virtual Apps
Unlike Windows (where VAC is a single, famous driver), Android handles audio routing very differently. Android does not have a native, system-wide "Virtual Audio Cable" driver that creates endpoints like "Line 1" and "Line 2." Instead, the concept is achieved through audio routing apps , virtual mixers , or screenshots/streaming tools that intercept the audio stream. Here is the breakdown of how it works, the limitations, and the best actual solutions.
Core Concept: What Does "Virtual Audio Cable" Mean on Android? On Windows, a VAC allows you to: virtual audio cable for android
Route output from App A (e.g., Spotify) to the input of App B (e.g., OBS). Create a feedback loop for recording internal audio.
On Android, due to security and app sandboxing, one app cannot directly capture another app's output unless:
You use root access. You use Android’s built-in Screen Capture or Internal Audio Capture APIs (Android 10+). You use a virtual audio device driver (requires custom ROM or kernel). While Android lacks a direct, one-click equivalent to
Method 1: Native Android Internal Audio (No Root, Limited VAC) Android 10+ introduced the ability for apps to capture "internal audio" during screen recording. Some apps have repurposed this into a virtual cable. Best App: AudioRelay or SoundWire While primarily for streaming audio to a PC, they create a virtual playback device that can be captured. How it works as a VAC:
Install AudioRelay on Android. Install AudioRelay Server on Windows. On Android, you route your music/game audio to the AudioRelay Virtual Output . On Windows, the server receives it and can pipe it into a real VAC (like VB-Cable) which then goes to OBS/Discord.
Verdict: Not a pure Android cable, but a bridge to a real PC cable. Screen Recorder - AZ Recorder The concept of
Method 2: Root Required – Kernel-Level Virtual Cable (True VAC) If your device is rooted (Magisk), you can install kernel modules that create real virtual audio devices. Tools:
