I'm a professional audio engineer and can make your music REALLY pop. I master using the finest outboard gear in my studio, applying analog compression and EQ. If it seems appropriate, I will also run it through a tape machine plugin. I generally charge $30 a song, but as I'm starting out on Fiverr I will master your track for only $5. No restriction on the length of the song.
Send me your wav files or mp3's. I will take care of the rest!
I have "2 days" as the length I will take to deliver, just in case, but in all likelihood I will return your file within 24 hours, sometimes sooner.
