Try adobe audition. Also vocals is the hardest part to record in a song. If audacity offers filters, try a cut off filter at around 80 hz. Next mess around with equalizers. Adobe audition offers general eq and parametric eq. Finally add reverb. If nothing avails email me ur vocal recording track and i will try to fix it as much as possible and then email it back to you. Good luck. furykacid@gmail.com
