The desired loudness of a finished audio track, especially after mastering, is a crucial consideration. Digital audio workstations (DAWs) often display audio levels in decibels (dB) relative to digital full scale (dBFS). The peak level, representing the loudest point in the audio, and the integrated loudness, a measure of the perceived average loudness over time, are key parameters. A mastered mix should generally aim for a specific integrated loudness target suitable for its intended distribution platform, while ensuring the peak level does not exceed 0 dBFS to avoid clipping or distortion. For example, streaming services like Spotify typically normalize tracks to around -14 LUFS (Loudness Units Relative to Full Scale), so a mix aiming for that platform might be mastered to a corresponding level.
Achieving an appropriate loudness level during the mastering process is significant for several reasons. It ensures the track sounds competitive in today’s environment, where listeners often compare audio from various sources. A well-mastered track, set to an appropriate level, maintains dynamic range while delivering a competitive perceived loudness. This prevents the track from sounding weak or quiet in comparison to others. Furthermore, adhering to the recommended loudness targets of specific platforms optimizes playback quality and avoids unwanted loudness adjustments by those platforms. Historically, loudness standards have evolved to address the loudness war, promoting a more balanced listening experience across different audio sources.
