Mastering
Mastering is the final stage of audio production where the completed stereo mix is processed and prepared for distribution. It involves tonal balance, dynamic control, loudness optimization, and ensuring the track meets streaming platform LUFS targets—typically -14 LUFS integrated for Spotify.
Mastering serves several distinct purposes:
1. Tonal correction: Subtle EQ adjustments to correct any frequency imbalances in the mix that weren't apparent during mixing (often due to room acoustics). 2. Dynamic control: Light compression or limiting to control peak transients and increase perceived loudness. 3. Loudness maximization: Using a brickwall limiter to bring the track to competitive streaming levels without clipping. 4. True Peak limiting: Ensuring inter-sample peaks don't exceed -1 dBTP for streaming delivery. 5. Format preparation: Dithering to 16-bit for CD, metadata embedding, and preparing distribution files.
For self-mastering EDM tracks, a common chain is: mild EQ → subtle compression → stereo widener → loudness maximizer/limiter. The target is a track that sounds balanced, punchy, and competitive in volume without sacrificing dynamics.
