Level gives a good balance between overall volume control on the Matches the average loudness of the Google Assistant TTS output. When playing back audio files using SSML, the average loudness shouldīe -16 LUFS (Loudness Units Full Scale) for stereo audio content, which

To compare audio material to the Google Assistant TTS output. Peak level is not a good measure of loudness and should not be used Maximum loudness of a digital waveform (0.0 LUFS). Loudness is a relative value used to compare digital programs based on the Physical measurement of peak air pressure change in a given acoustic situation. LUFS is also known as LKFS (Loudness, K-weighted, relative to Full Scale) Note: Volume is distinct from loudness.

Listening volume and lets audio producersĪvoid jumps in amplitude that would require users to constantly adjust volume.

LUFS is a complicatedĪlgorithm based on perceived loudness of human hearing at a comfortable Normalization across many genres and production styles. LUFS (Loudness Units relative to Full Scale) is a standard that enables volume
