Is It Possible to Use OBS to Capture Audio Only - Guide & Alternatives

Are you curious about the possibility of recording just an audio with OBS? Although OBS Studio is popular for streaming consistency, recording audio only presents some difficulties. If clear audio is needed without requiring video, solutions are simple. In this article, we will take you through the processes of recording audio on OBS, saving it as an audio-only file, and the most efficient tools for recording audio on Windows and Mac computers.

Part 1. Can OBS Record Audio Only

No, OBS Studio allows audio to be captured only as a secondary channel but not as the main channel. Since OBS was developed primarily with screencasting and commensurate streaming in mind, users must have at least an audio and video source for the software to work. However, users could also turn off all video sources and only record desktop or mic audio sources that are video-less.

Still, some form of video recording is a requirement due to video tracks being included. If the intention is to capture sound only, OBS can perform the recording function while allowing users to subtract the file from the video using third-party applications. Furthermore, Mac users are required to use more programs to record internal sound for other reasons packeted with the system. Recording just sound waves uses volumetric measures, is tedious and needs to be better integrated with OBS.
