RTW SW32002 - Loudness and SPL License for TouchControl 5

The Loudness and SPL license expands the basic PPM instrument with graphical and numerical instruments for loudness measurements as described in current loudness guidelines (EBU R128, ITU-R BS.1770-4/1771-1, ATSC A/85, ARIB, OP-59, AGCOM, CALM, LEQ(M), TASA, SAWA). The range of metering instruments is extended with RTW's highly recommended LRA instrument for the graphical display of the Loudness Range.

• Full implementations of the latest loudness standards and recommendations
• Bargraphs for summed Loudness with Momentary, Shortterm, Integrated values, and Loudness Range (LRA)
• Numerical display of all relevant values like M, S, I, LRA, TPmax, Mmax, Smax, Itime
• Adds the LRA instrument

For signals with more than four channels, software license SW32001 is required.

Loudness Sum
With the Loudness Sum instrument you get a bargraph display of the summed Loudness values M, S, and/or I of a Loudness measurement acc. to EBU R128, ITU BS.1770-4/1771-1, ARIB, ATSC A/85, OP-59, AGCOM, CALM Act, LEQ(M), TASA, SAWA, or specified by customer. A SPL meter is also included.

Loudness Num
With the Loudness Num instrument you can monitor some or all relevant values of a loudness measurement on a numerical display: M, S, I, LRA, TPmax, Mmax, Smax, Itime.

LRA (Loudness Range)
The LRA (Loudness Range) instrument displays a graphical representation of the loudness variances within short time periods. These are measured against the Loudness Range (LRA) descriptor specified in EBU R 128. It is used to show whether a program has a continuously constant loudness or a high variation between low and high level components. It allows for making assumptions on whether the program has seen or requires dynamic processing with regard to the intended distribution path.
