Another type of normalization is based on a measure of loudness, wherein the gain is changed to bring the average loudness to a target level. This average may be approximate, such as a simple measurement of average power (e.g. RMS), or more accurate, such as a measure that addresses human perception e.g. that defined by EBU R128 and offered by ReplayGain, Sound Check and GoldWave.

The practice of focusing on loudness in audio mastering can be traced back to the introduction of the compact disc, [3] but also existed to some extent when the vinyl phonograph record was the primary released recording medium and when 7-inch singles were played on jukebox machines in clubs and bars.
Signal-to-noise ratio (SNR), however, is the ratio between the noise floor and an arbitrary reference level or alignment level. In "professional" recording equipment, this reference level is usually +4 dBu (IEC 60268-17), though sometimes 0 dBu (UK and Europe – EBU standard Alignment level).

Linear timecode waveform as displayed in Audacity with 80 bit data frame highlighted. The basic format is an 80-bit code that gives the time of day to the second, and the frame number within the second.
Dialnorm is an integer value with range 1 to 31 corresponding to a playback gain of −30 to 0 dB (unity) respectively. Higher values afford more headroom and are appropriate for dynamic material such as an action film. Dolby recommends that the dialnorm value be determined by measurement of average dialog level in the program.
