Supplying your audio correctly greatly increases the mastering potential and the ability to provide the best possible results. Our desire is to deliver a final mastered audio file with outstanding professional sound. These results can only be achieved if the audio files you provide to Label Worx follow some simple specifications.
Raw Audio File Requirements
We can achieve a far more superior result if you follow some simple rules and visibly check your audio
files prior to uploading them to our LMS Mastering System. It is a common problem that artists and
producers deliver part mastered or part processed files to a record label expecting them to master the
This article provides some simple information and highlights some techniques to enable you to ensure your audio files are ready for mastering. If they do not meet these requirements then there is no harm in asking the producer or engineer of the original audio for another export of the track.
Please try to ensure that the following rules are met were possible:
- Naked Files - All files for mastering need to be a naked export with full dynamic range.
- Leave Headroom - Leave a minimum of -3db headroom in the track.
- No Post Processing - When exporting audio your engineer should leave the master channel clear.
In order to visibly check the WAV forms of your audio files we recommend using a professional application such as Logic, Ableton or Pro Tools. There are however many other applications that will get you the same results including open source audio editor Audacity that is available for free download.
