Professional Mastering Service


What is Mastering?

Mastering uses effects such as compression, limiting, and equalization plus others to enhance the OVERALL sound of your music. Your music will be comparable in presence and volume to commercially released recordings after it has been mastered.

How does it work?

  1. After confirmation of payment, you will receive notification of upload instructions from ums.tunecore@umusic.com within two business days.  Please be sure to check your Spam folder just in case. There is no login necessary to UMS. If you are using Internet Explorer, you have to go into your Cookies and allow the UMS website for viewing. Copy and paste the URL you get after clicking Submit or Upload audio on the bottom of the page. Or, we suggest you use a different web browser like Firefox where no login is necessary.
  2. Please be sure to upload your audio files according to the following format: WAV or AIF files, 44kHz (sample rate)/16 bit (sample size) or 48kHz/24bit. These files must be the final mix of the song with NO peak-limiter (e.g. normalizer, finalizer - L2, L3). Other effects like EQ, compression are okay to leave on the mix buss. Be sure to keep the overall level to about -3dBfs. So for each song, you will upload 1 audio file. We cannot accept MP3s due to their low quality.
  3. The engineers will do what they feel is musically best for your project. If you have any special mastering instructions for the engineer, please upload an additional text file when you are uploading your audio files.
  4. If your audio files are OK in format, you will then receive an email with final mastered audio content from UMS in 14 business days from the day you uploaded. It will have “WAM!NET Package” in the subject line and will be sent to address you provided when you uploaded your music.
  5. Do you also do Mixing?

      Yes! Please see our Mixing page here for more information.
