Mastering is the last, but also a very important step in audio production. All your hard work shines through with professional mastering. Wether it's a song or a voice over or just an instrumental piece. Mastering provides the absolute best quality out of your work that maximizes the volume so your listeners will be satisfied.
A normal rate at a high profile studio would average at $75 per hour. With my services, $5 gets you a standard master for 4 minutes of audio, but to make sure your audio sounds the absolute best, order the gig extras.
