Frequently Asked Questions
Why Should You Choose an Online Mixing and Mastering Services?
It is easier than ever to record, mix, and master your song in your bedroom these days. It’s even easier to release the song for the world to hear. However, with so many people on the same playing field now, you must find ways to separate yourself from the pack.
Having your song professionally mixed and mastered gives you three huge advantages over the compention.
- Your songs will sound more precise, louder, warmer, and have the ability to compete with other songs from major artists that were professionally mixed and mastered.
- Music is supposed to be a collaborative effort. Having a trained mixing and mastering engineer work on your song can add new creative and sonic differences that you might not have thought of. These changes could be what makes or breaks your song.
- The technical knowledge that is needed to deliver a professionally mastered song for distribution can take years to learn and understand. Sometimes it’s best to hand your song over to someone who knows all the details so you can spend more time on being creative.
What is the difference between Mixing and Mastering?
Mixing is when you take all your individual tracks and blend them together using compression, EQ, reverb, delay, and a host of other effects to make it sound like one cohesive piece. This is also the time you would pitch correct and line up vocals.
Mastering is the final stage of the song making process. This is where you add the final sparkle to the mix and make sure it will stand up comparably in quality and loudness to commercially released music.
