OBS or Open Broadcasting Software is a free and open-source internal audio recorder for PC. This multiple-platform recorder is well-known for its robust capabilities in screen recording and live streaming. It can record up to six separate audio tracks. Note that OBS studio has no audio-only mode. Thus, if you want to capture audio only, you can record the audio without adding the video source. But the export recording will be saved in a video format. You have to export the recordings to other programs or services in order to obtain a separate audio file. In such a case, OBS is probably not the greatest option. But for tech-navy users, OBS offers advanced options to manually configure settings for optimal recording performance.
