streaming mode | Loudness/dynamics category
- signal (real) - the input signal (must be non-empty)
- leq (real) - the equivalent sound level estimate [dB]
This algorithm computes the Equivalent sound level (Leq) of an audio signal. The Leq measure can be derived from the Revised Low-frequency B-weighting (RLB) or from the raw signal as described in . If the signal contains no energy, Leq defaults to essentias definition of silence which is -90dB. This algorithm will throw an exception on empty input.
