Record sound of a specific application

[KMint1819]

Hi, thanks for this wonderful library!

After trying out a bit, I'm wondering that if we can use this library to record a specific running application that is playing sound? Ex. I have Spotify and Youtube(Chrome) playing on the same time, but record only sound from Youtube. Thanks!

I think this is generally possible with Windows' sound APIs, but not currently implemented in SoundCard. You can record the entire system output, though. You might also be able to create a virtual sound card with a third-party tool, play only spotify or Youtube on that sound card, and record that through SoundCard.
