Track Volume
LUFS TargetsStreaming applications like Spotify, Apple Music, and YouTube use automated leveling tools to match all music catalog files to a balanced playback standard.
Too Hot: Bouncing your master file past target parameters forces streaming algorithms to turn down your track's gain, compressing transient punch.
Too Soft: Leaving files below target margins results in weak playback volumes when your track is queued up back-to-back with commercial masters.
Distortion Guard
Peak HeadroomWhile average loudness tracking monitors long-term playback energy, your distortion safety ceiling monitors the absolute highest microsecond wave spike inside the audio signal container.
When platforms accept your uncompressed master WAV file, they transcode it into delivery formats like AAC or OGG. This compression naturally causes your peak levels to expand upwards. If your file contains zero safety headroom, this conversion process triggers inter-sample clipping—causing crackling distortion on consumer playback devices.
