Analysis result of “DD DÉ MOUSE” and “be yourself” by AI Mastering
Loudness time series
How can I get the same sound pressure as "DÉ DÉ MOUSE" and "be yourself"?
According to the analysis results, the loudness of "be yourself" is -7.6 dB, so I think that it is better to set to a target sound pressure a little larger than that in AI Mastering and mastering.
Because the target sound pressure is high, the Ceiling setting is recommended "Peak" or "True Peak". "True Peak (15 kHz Lowpass)" is too conservative for clipping because it lowers the peak so that it does not clip if it is cut more than 15 kHz due to re-encoding, etc.
If you set "True Peak", it is recommended to set oversampling to 2x.
