What is the audio recorder for PC from both internal and external sources?

About the audio recover for PC. In my own experience, I found OBS great for recording streams or gameplay but kinda clunky if I just want quick, straightforward audio extraction. For simple audio recovery, dedicated tools like V0icemeeter are often easier and lighter on your system. if you're thinking about using OBS Studio just for audio recover or capturing audio on your PC, there are a few downsides you might run into:

1. OBS is mainly built for streaming and recording videos, so it might be overkill if you're just trying to grab audio. It’s like using a sledgehammer to crack a nut — more complex than you need.
2. It can be pretty heavy on your CPU and RAM, especially if you're running other stuff at the same time. This might cause your PC to slow down or lag, which is annoying if you're trying to do something quickly.
3. Getting it to just record or recover for PC can be a bit confusing at first. You need to fiddle with scenes, sources, and audio mixer settings, which might be overcomplicated for simple audio recovery.
4. There can be some slight delay or latency when capturing audio, especially if you're running other demanding apps. This might not be ideal if you need real-time audio.
5.  It’s not built for editing audio clips. After capturing, you’ll need another tool to clean up or tweak the audio, which adds extra steps. Sometimes, certain audio drivers or software conflicts can cause issues with capturing audio properly, leading to no sound or poor quality.
