My issue that I would like help with is that I can’t seem to isolate vocals from a song. I’m following this Audacity tutorial on vocal isolation that uses the instrumental track to isolate vocals (link to tutorial page: https://manual.audacityteam.org/man/tutorial_vocal_removal_and_isolation.html). I have been following the steps listed in that section (with both tracks properly aligned), and tried to mix and render. However, the end result is the song with muddier instrumentals; the vocals could not be isolated. I did ensure that both tracks have the same bit rate of 192 kbps (though I’m not sure if that has a major impact or not). I have attached a Google Drive link to a folder that contains the audio tracks for both the original song and the instrumentals for reference (link: https://drive.google.com/drive/folders/11Korbi_8oG9xDdXlPjlBGgjUmItOAVRn?usp=sharing). Any and all help is very much appreciated! Thank you in advance for your time!
