Dear All,

I have written a small test application to calculate Average RMS and max RMS power of

a wave file. Wave file audio data having 16 bit sample and mono.

i'm using the following algorithm :

i=N-1

rms = sqrt(1/N ∑ sample[i] * sample[i] )

i=0

AvgRMS = 20.0 * log10 ( rms /2^N-1);// for RMS power in dB.

When i compared the AvgRMS value with adobe audition, it matches with Total RMS

power instead of Average RMS power but i want to calculate Avg RMS power.

Can you advise me where I'm wrong to calculate Average RMS power in dB.

Thanks in advance.

Best Regards
