6. On the Monitor application, change the rendering mode to the desired format: 7.1 or

5.1.

7. Proceed with live monitoring, print-master recording, or print-master playback.

--rerenderSurroundCrossover (Bass Management Routing)

The --rerenderSurroundCrossover command-line option (in Hz) routes bass

management of surround speakers to LFE during re-rendering, rather than to the bass

management speakers that were assigned to speakers for rendering Dolby Atmos (via the

Dolby Atmos Designer). This prevents loss of bass material.

When re-rendering to 7.1, the crossover is applied to Left Side Surround (Lss), Right Side

Surround (Rss), Left Back (Lb), and Right Back (Rb) speakers. When re-rendering to 5.1,

the crossover is applied to Left Surround (Ls) and Right Surround (Rs) speakers. For both

7.1 and 5.1, the bass from those crossovers (in addition to bed LFE) is summed into LFE.

When

–-rerenderSurroundCrossover is specified (with a valid range of 0 and above, in

Hz), the renderer applies a crossover at the specified frequency and the bass content is

preserved and summed into the LFE. Typical settings are 50–150 Hz. The bass content is

cut by 10 dB to account for the LFE being calibrated 10 dB higher than other speakers.

If there is more than one speaker in the LFE array, the energy is distributed to all the LFE

array speakers.

When

--rerenderSurroundCrossover is not specified, the renderer applies the default

crossover at 120 Hz, maintains the high content in the surround arrays, and discards the

bass content. This behavior also occurs if you specify an invalid argument (such as a

negative value or nonnumeric value).

--rerenderSurroundGain (Master Trim Control)

The --rerenderSurroundGain command-line option (in dB) provides a master trim

control for re-rendering to 7.1 or 5.1.

When re-rendering to 7.1, the trim is applied to Lss, Rss, Lb, and Rb speakers. When re-

rendering to 5.1, the trim is applied to Ls and Rs speakers.

When

–-rerenderSurroundGain is specified (with a valid range: 10 and below, in dB),

the renderer applies the trim. For trim values below 0 dB, use a minus sign, followed by

the value.

When

--rerenderSurroundGain is not specified, the renderer applies the default trim

of 0 dB (no trim). This behavior also occurs if you specify an invalid argument (such as a

nonnumeric value).
