If you are a content creator or streamer, you likely just need to capture internal sound. Here is the standard workaround using modern Android features:
Because of this security architecture, you cannot simply download a direct clone of VB-Cable for Android that works globally across all apps. Instead, developers and users must utilize specific Android APIs (Application Programming Interfaces) or specialized hardware configurations to achieve the same result.
| Use Case | Best Solution | Root Required? | Latency | |----------|---------------|----------------|---------| | Send Android audio to OBS on PC | AudioRelay → VB-Cable (PC) | No | ~20 ms | | Route music from Phone to Discord (Phone) | Audio Repeater (Mic loopback) | No | ~300 ms | | Create a true virtual input for Termux audio | ALSA Loopback + tinyalsa | Yes | ~5 ms | | Record internal audio + microphone | Android 10+ built-in screen recorder | No | Zero (file-based) | | Real-time effect processing between apps | Not possible without custom ROM | N/A | N/A |
An open-source utility available on GitHub and select app stores that allows you to forward audio packages to specific endpoints. virtual audio cable for android
For maximum clarity, use a dedicated DAC/ADC converter, such as the Cubilux USB C to 3.5mm Adapter, which supports high-quality 96KHz/24-bit audio recording.
Method 2: Hardware-Assisted Virtual Routing (The Most Reliable Way)
Modern Android versions (Android 10 and above) allow apps to capture system audio internally. If you are a content creator or streamer,
The system only captures audio categorized as usage type USAGE_MEDIA , USAGE_GAME , or USAGE_UNKNOWN . Best Android Apps Using This API
Rooted devices running Magisk can install advanced audio frameworks. Modules like or JamesDSP allow users to hook into the system's core audio server (AudioFlinger).
The phone sends media audio out through the USB port to the interface. | Use Case | Best Solution | Root Required
The hardware "Loopback" switch mixes that internal audio with an external microphone.
However, there are several "workaround" methods to achieve similar results depending on your goal. 🛠️ Top Solutions & Alternatives
