[arm-allstar] real world audio values *CORRECTED*

[David McGough]

Hi Chris,

I just looked back at those original numbers and realized I made an 
error---I used the incorrect exponentiation function in Octave.  *SIGH*
...See below.

Here are the corrected values, as output from a simple C program:
---------------------------------------------------------------------

[root at RPi4B-dev ~]# cat dsplvl.c
#include <math.h>
#include <stdio.h>

void main()
{

	for (double db = 0; db > -61; db -= 1.0) {
		int i;

		i = (int)(999.0 * pow(10.0, db / 20.0));
		printf ("txdsplvl = %3.1d, target db = %5.1lf, real = %6.4lf\n", i, db, 20.0 * log10( (double)i / 1000.0));
	}

}
