Reference mastering

Upload your mix and a reference track. SoundBooster compares their tonal balance, loudness and stereo width and builds a master that moves your mix toward the reference, with an amount control so you can match it fully or just lean towards it.

You can paste a Spotify link to fetch the track's title and artwork for your notes, but Spotify doesn't allow downloading its audio — to match a track's sound you need to upload an audio file you have the right to use.
