Use DroidCam with OBS

The short answer

DroidCam can feed a phone's camera into OBS Studio. There are two ways to do it. One is a dedicated OBS plugin that adds a DroidCam source. The other is the desktop client's virtual webcam, which OBS treats like any other video capture device. The main limitation for speech is audio. Whether the phone's microphone reaches OBS depends on which route and which app version you use, and a wireless link can make the voice drift out of step with the picture. Many setups get cleaner, more predictable speech by using the phone only for video and recording the voice with a microphone connected directly to the computer.

Two ways to bring DroidCam into OBS

• OBS plugin route: install the OBS-oriented DroidCam app on the phone and the matching plugin on the computer, then add the DroidCam source in OBS. This skips the separate virtual webcam driver.
• Desktop client route: run the DroidCam desktop client, which creates a virtual webcam. In OBS, add a Video Capture Device source and select that device.
• Connection: both routes generally work over Wi-Fi or USB. On Android, USB mode typically requires enabling USB debugging on the phone.

App names, packaging and plugin pairings have changed between releases. Check the developer's current documentation to confirm which phone app goes with which desktop component before installing.

Where the voice comes from

In OBS, an audio input is any source that brings sound into the mixer, such as a microphone, a capture device or a virtual audio device. When you use DroidCam, you choose whether the voice travels from the phone along with the video or arrives separately from a microphone on the computer. Each choice affects clarity and timing differently.

Voice source | How it reaches OBS | Speech considerations

Phone microphone through DroidCam (where the version supports audio) | Carried within the DroidCam source, or exposed by the client as an audio device you add with Audio Input Capture | Travels over the same link as the video. The phone usually sits at camera distance, so it picks up more room sound. Dropouts or delay on the link affect the voice too.

Computer, USB or interface microphone | Audio Input Capture source, or the Mic/Aux device in OBS audio settings | Independent of the phone link and can be placed close to the speaker. Usually needs a sync offset because the phone video arrives later than local audio.

Headset microphone | Same as a computer microphone | Fixed close to the mouth, which reduces room echo and keyboard noise. Visible on camera.

Keeping speech in sync with the picture

Video sent from a phone, especially over Wi-Fi, often reaches the computer slightly later than audio from a locally connected microphone. OBS can compensate with the Sync Offset setting in Advanced Audio Properties, which delays an audio source by a set number of milliseconds. To find a usable value, clap once on camera, make a short recording, and compare when the clap sounds with when the hands meet. Then adjust the offset and test again. The right value depends on your network, connection type and settings, so it has to be measured on your own system.

Practical checks for clear speech in OBS

• Keep one voice source active. If both the phone microphone and a desk microphone capture your voice at slightly different delays, the combined sound can become hollow or phasey. Mute or remove the one you are not using.
• Watch the audio mixer meter. Speech peaks should stay below the red zone. Clipping, where the signal exceeds the maximum level, produces distortion that cannot be removed afterward.
• Apply filters sparingly. Noise Suppression reduces steady background hiss. A Noise Gate silences the input below a set threshold. A Compressor narrows the gap between loud and quiet words. Too much of any of these makes speech sound unnatural.
• Monitor through headphones rather than speakers so the microphone does not pick up its own output and cause echo or feedback.
• Prefer USB when stability matters. A wired connection is generally less exposed to the congestion and dropouts that affect Wi-Fi, and those problems are heard more easily in audio than seen in video.
• Mind microphone distance. A microphone closer to the mouth captures more direct voice relative to room reflections, which is why a phone used as a camera is often a weaker speech microphone than its hardware alone would suggest.

Using the OBS output in video calls

The OBS Virtual Camera sends video to conferencing apps but not audio. In the call app, you still need to choose a microphone. You can either select the physical microphone directly, which is the simplest option, or route OBS's processed audio through a virtual audio device if you want callers to hear your OBS filters. If you process audio in OBS, consider turning down the conferencing app's own noise suppression, because stacking two processing stages can produce warbling or clipped word endings. A short test call will show whether the combination works.

Gaps in the available evidence

No measured data was available for this guide on DroidCam's audio quality, latency, supported sample rates or current per-version feature list, and no comparison with dedicated webcams or microphones was tested. The guidance above relies on the general behaviour of OBS and of phone-as-webcam setups. Confirm current audio support in DroidCam's own documentation, and measure sync and speech levels on your own hardware.
