Seamless Windows Integration
Our Windows client integrates Micstream into Windows by creating a virtual microphone
device that any application can use — from Discord and Zoom to OBS and professional
recording software.
This virtual device is powered by a custom audio driver that delivers studio-quality sound
using 32-bit floating point precision at 48kHz sampling rate — no other app in the Play Store
comes close.

Low-Latency Streaming
To stream microphone audio to Windows in ultra-low latency, our mobile app uses Google's C++ Oboe library. Flagship devices achieve less than 10ms latency via USB — making it perfect for real-time applications like live streaming, gaming, and video calls.

Yes. Any modern Android device will work. Flagship phones usually provide better audio quality.
To make Windows treat your phone like a hardware microphone, Micstream needs to create an actual microphone device. Our driver does exactly that — it creates a virtual mic device that seamlessly integrates with apps like Discord, Zoom, Google Meets or OBS.
No. The driver runs alongside your existing audio devices without affecting them. Micstream simply adds a new, virtual microphone to your system.
USB provides ultra-low latency—often under 10ms on high-end devices. Wi-Fi performance varies based on signal strength and network conditions, so latency may be higher.
Yes, depending on your device. Many phones have built-in microphones that already outperform budget USB mics. Most USB mics around the $70 price range are stuck with 16-Bit audio depth — flagship phones often record in 24-Bit audio. Because Micstream's pipeline is 32-bit float and 48kHz at all stages, no downsampling hapens and you can achieve professional-quality sound.
Micstream uses 32-bit floating point audio at 48kHz throughout the full pipeline. We never downsample or compress below these specs.
Yes. You can adjust your device's volume settings, effectively controlling gain. Future updates may offer more advanced audio controls.
No. We do not store or capture user audio or personal data. No data is sent to external servers. Refer to our Privacy Policy for details.
