How to Professionaly Prepare Your Tracks for Audio Mastering

Ensuring a smooth transition into the mastering stage is crucial to the success of any music project. Preparing your tracks properly for professional audio mastering can elevate your music and help the mastering engineer to enhance your work effectively. This article will offer an in-depth guide on how to prepare your tracks for professional audio mastering.


1. Perfect Your Mix

The quality of your mix directly influences the final master. Your mix should sound as close as possible to how you want the final track to sound, minus the overall loudness and polish that mastering will provide.

  • Balance: Make sure the levels of all elements are well balanced, and that no particular instrument or frequency band is overwhelming the others.
  • Clarity: Every element should be clearly audible and have its own 'space' in the mix.
  • Dynamics: The dynamics of the mix should be well controlled,
  • Panning: Proper use of the stereo field can bring your mix to life. However, be cautious not to pan too drastically, which can cause an imbalanced stereo image.
  • EQ: Carefully use EQ to clean up any muddiness and to allow each instrument to shine in its own frequency range.

2. Mind the Headroom

Leaving adequate headroom in your mix is vital for the mastering stage. This is the space between the highest peak in your audio and 0dB (the maximum level before digital clipping occurs).

  • A good rule of thumb is to aim for your mix to peak at -6dB. This leaves plenty of room for the mastering engineer to manipulate the audio.
  • If your mix is peaking at -3dB or above, you may need to go back to the mix and reduce the levels of some elements.

3. Check Your Phase Relationships

Phase issues can severely degrade the quality of your audio and cause problems during mastering.

  • Use tools like phase correlation meters to spot any phase problems, and correct them at the mix stage.
  • If you are using a stereo widener, be sure to check the phase relationship between the left and right channels. If the phase correlation is too low, it can cause mono compatibility issues.

4. Keep Processing to a Minimum

Avoid using any mastering specific processors like a limiter or loudness maximizer on your master bus.

  • These are tools that a mastering engineer would typically use, and they can restrict what can be done at the mastering stage.
  • If you are using any processing on your master bus, be sure to disable it before exporting your mix. In some cases you can reduce your wet signal if the plugins have a FX mix control to bring the power of post processing down.

5. Export the Correct Format

Export your pre-master in a high-resolution, lossless audio format such as WAV or AIFF.

  • 24-bit or 32-bit depth is recommended. This provides a high level of detail and dynamic range.
  • The sample rate should be the same as your project's sample rate. Common sample rates are 44.1 kHz, 48 kHz, or even higher.
  • If you are exporting a stereo file, be sure to export it in stereo. If you are exporting a mono file, be sure to export it in mono.


Taking the time to prepare your tracks for professional audio mastering can significantly improve the outcome of the final product. A well-crafted mix, sufficient headroom, proper phase relationships, minimal processing, correct export format, and clear communication can all contribute to a successful mastering process and ultimately, a superior sounding track.
