I'm recording material from Spotify. I know their native file stream is encoded in OGG Vorbis. When I save in that format, has the stream been transcoded in an intermediate step in Jaksta music recorder, or am I capturing the raw Spotify stream?
Jaksta audio records from the windows audio subsystem.
In Application recording mode, Jaksta is recording directly from the windows audio subsystem. This is uncompressed WAV. It is then encoded to the output format you have requested in your settings.
Eg: Sportify encoded stream (OGG Vorbis) -> unencoded audio in Windows Media Subsystem -> Jaksta encodes as per your settings
If you are recording via "Stereo mix (play what you hear)" then it is recording from the speaker at the quality configured in Control Panel > Hardware and Sound > Manage Audio Devices > Select your speaker > Properties > Advanced tab > Default Format section.
Eg. Sportify encoded stream (OGG Vorbis) -> unencoded audio in Windows Media Subsystem -> Speaker quality cfg -> Jaksta encodes as per your settings
Thanks! That clears it up for me.
