The purpose of the AudioLevelizer audio object is to automatically adjust and balance the loudness of incoming audio signals, regardless of the input from different audio sources. Basically, this audio object allows you to continuously maintains the perceived loudness of audio sources without performing volume adjustments when switching between audio sources.<\/span><\/p>\n

It induces a fixed latency of 512 samples (~10 ms at 48 kHz sample rate) between the audio input and the output.<\/span><\/p>\n

Example: Tuner > USB. The AudioLevelizer will adjust the volume automatically to make sure the perceived loudness will be equal after the source switch.<\/span><\/p>\n
