1) Yes, Our VAS(virtual audio streaming) supports recording
Spotify. In fact, VAS can record all the sounds you hear with one click. VAS is a virtual sound card, so it can records all the 'what you hear' sound data easily .
As to removing Ads in Spotify, it is a complicated thing. Our VAS can automatically remove some kind of Ads, if the Ad is in a different audio streaming. This is one of the unique features of VAS. See:
auto split recorded sounds per audio streamhttp://www.virtualaudiostreaming.net/support.html2) VAS supports recording to both Wav and MP3. It has a built-in MP3 recorder. It also works with other audio recorder.
However, current version does not support artist, album, etc. Good news is many users have asked for this feature, so we will add this feature in the future release.
