Audio Mastering Frequently Asked Questions

Explore The SoundLAB

Why is CD mastering necessary?

In the recording studio, you record one song at a time, and the focus of the recording or mixing engineer is to make each song great. The result, however, is generally a collection of songs that all peak at different levels and may have different EQs. In the post-production phase (called Audio Mastering), a professional engineer unifies the CD by using EQ, compression, and other dynamics processing to give it a consistent sound from track to track.

What does audio mastering do for my album’s sonic quality?

Mastering can raise your album's overall level through the careful use of compression, so your album can compete with any major label release. The mastering engineer also ensures that your music will sound great - whether it's being played through a car stereo, a portable CD player, or a top-of-the-line stereo system. In mastering, the sound of your CD will be optimized, making it sound punchy, warm, and full, while raising the overall level (volume) and highlighting details that aren't already apparent. Mastering is also helpful for addressing issues such as "pops," out-of-phase tracks, and overall noise reduction. Hear what audio mastering could do for your music.

How does having the SoundLAB review my master help me?

A fresh pair of ears can be the difference between a good-sounding CD and a great one. A real advantage of mastering is that an unbiased sound professional has the opportunity to evaluate your master and determine how to get the most out of your production. After you've spent weeks or even months in a recording studio listening to your CD over and over again, a fresh pair of ears can put the project into perspective for you and let you know whether or not your CD will benefit from post production. After all, you only have one chance to make your music sound its best. Get a FREE audio mastering review.

What formats of audio master do you accept?

We can accept your master on one of the following formats:

  • Audio CD
  • Data files (wav, aiff, FLAC, etc.) on CD-R, DVD-R, flash drive, or via upload.
  • Digital Audio Tape (DAT)
  • DDP file set (on CD-R, DVD-R, flash drive, or via upload)
  • 1/2" or 1/4" Analog Tape
Handle all masters carefully, both before and after recording. Touch CDs only by the edges and keep them free of fingerprints and scratches that can cause data errors. Make sure your master is clearly with your contact information. Learn more about preparing a physical master for replication.

Absolutely. We’ll send you an audio reference CD or electronic proof online for you to listen to and review. It’s the perfect time to compare how much mastering can do for your album. Listen to your original CD master after listening to your audio reference and you’ll hear the difference. Crisper highs, thundering lows and punchy mids bring your vision to life.

Can I master my own CD?

What else do you need besides my audio master?

You must complete a SoundLAB Questionnaire and Track Listing Form with your audio master. Required information on the Track Listing Form includes a complete and accurate running time log listing all events (tones, silences, songs, outtakes, noises, etc.) as they occur. The SoundLAB questionnaire gives you the opportunity to provide us some important information that we can reference when mastering your project. Things such as overall volume, EQ, editing, and spacing preferences, or other artists or recordings you like the sound of, should be provided here for the engineer working on your project. For CDs, the maximum length is 79:45 minutes. For programs over the industry recommended 78:00 total time, you must submit a signed disclaimer form with your order.
