Loudness Units Full Scale (Integrated) measures the average loudness of your entire track. Spotify and Apple Music typically normalize audio to -14 LUFS. If your mix is significantly louder (e.g., -8 LUFS), it will be turned down by streaming algorithms.
Unlike standard sample peaks, True Peak accounts for inter-sample peaks that occur during digital-to-analog conversion. Keeping your ceiling at -1.0 dBTP ensures your music won't distort when converted to lossy formats like MP3 or AAC.
This is the difference between your peak and RMS levels, representing your dynamic range. A Crest Factor of 8-14 dB is generally considered healthy. A very low number suggests your mix is over-compressed, while a very high number may lack "glue" and impact.
Measures the phase relationship between left and right channels. A value of +1.0 is mono, while 0.0 is wide stereo. If your meter dips into the negative (red zone), you have phase cancellation issues that will make elements disappear on mono speakers.
Calculates how much energy is lost when your stereo mix is summed to mono. Keeping this loss below 1.5 dB ensures your mix translates well to club systems, phones, and Bluetooth speakers.
The checker analyzes Sub/Bass, Warmth, and Air. These ratios are genre-dependent, but significant deviations usually indicate a need for corrective EQ on your master bus to match commercial spectral profiles.
This tool utilizes the ITU-R BS.1770-4 standard for loudness measurement to provide broadcast-accurate technical data.
It checks integrated LUFS, momentary loudness, estimated true peak, sample peak, clipping, crest factor, stereo correlation, mono loss, stereo width, and broad spectral balance.

Many streaming services normalize playback around -14 LUFS, but genre and taste still matter. Use the reading as a technical reference, then decide whether the song still feels alive.
