VU meter controls.
When enabled, VU reports are sent automatically at approximately the requested rate in the same format as responses to a
“get” command. VUs appear in a “vu” response. The value is a 4-character string. Each character is one of:
0123456789ABCDEFG. The first character is the compressor RMS input level. The second character is the compressor gain
reduction level (0 dB = no compression). The third and fourth characters indicate the left and right channel peak output level.
VU meter characters:
G = 0 dBFS
F = -2 dBFS to -1 dBFS
E = -4 dBFS to -3 dBFS
D = -6 dBFS to -5 dBFS
C = -8 dBFS to -7 dBFS
B = -10 dBFS to -9 dBFS
A = -12 dBFS to -11 dBFS
9 = -15 dBFS to -13 dBFS
8 = -17 dBFS to -16 dBFS
7 = -20 dBFS to -18 dBFS
6 = -24 dBFS to -21 dBFS
5 = -28 dBFS to -25 dBFS
4 = -34 dBFS to -29 dBFS
3 = -42 dBFS to -35 dBFS
2 = -54 dBFS to -43 dBFS
1 = -65 dBFS to -55 dBFS
0 = less than -65 dBFS
get or set VU meter rate: vurat
The value indicates the number of input VU reports per second, and is an unsigned integer between 0 and 30. A
value of 0 turns off input VU reports. Once the input VU report rate has been set, VU reports are sent automatically
at approximately the specified rate.
Examples:
=svurat:10! select 10 VU reports per second
=svurat:0! turn off VU reports
