Windows Integration
What Micstream does
By default, Windows doesn't recognize your phone's mic.
Micstream installs a tiny driver that makes your phone appear like a standalone microphone — recognised by Zoom, Discord, OBS, or any other Windows application.

Comparison
Unmatched audio quality
The audio format that your PC microphone app supports determines whether you get studio-quality sound or limited, distorted audio. Most apps use outdated 16-bit formats that can't handle professional recording needs.
Micstream is the only phone-to-PC mic app that preserves true 32-bit floating point audio from your phone to Windows.

Frequently Asked Questions
Micstream supports Windows 10 and Windows 11.
Not yet. We're focused on delivering the best Windows experience first. Stay tuned for updates on other platforms.

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.
