Measure integrated loudness and loudness range

`loudness = integratedLoudness(audioIn,Fs)`

`loudness = integratedLoudness(audioIn,Fs,channelWeights)`

```
[loudness,loudnessRange]
= integratedLoudness(___)
```

specifies
the channel weights used to compute the integrated loudness. `loudness`

= integratedLoudness(`audioIn`

,`Fs`

,`channelWeights`

)`channelWeights`

must
be a row vector with the same number of elements as the number of
channels in `audioIn`

.

`[`

returns the loudness
range of the audio signal using either of the previous syntaxes. The
EBU R 128 Tech 3342 standard defines the loudness range computation.`loudness`

,`loudnessRange`

= integratedLoudness(___)
