Will consider that. Thanks. Does @rbj's answer consider the artifacts you've mentioned? If not, could you please give a lead on how to include these?

This is an interesting and informative perspective. That's correct. I am looking at audio samples, which is more often than not a speech signal and hence a combination...

This looks really good (and more inclined towards textbook definition of gain). Is this independent of factors like DC components and noise? I'm looking to apply...

Is RMS a good metric to estimate gain

New thread started 2 years ago
I have two vectors V1 and V2. V1 is the source signal vector and V2 being the (possibly) degraded (attenuated/amplified) output signal. I have calculated the RMS...
Hi niptoz, I'm looking for a solution for a similar problem as yours as mentioned here - basically, calculate the delay of an audio captured over microphone (a...
Thanks a lot. This helped. Exactly what I wanted to understand regarding the maxLag parameter of xcorr.
Thanks for the pointer on normalization.Sorry, I meant on the number of correlation coefficients in the correlation vector. I understand that the peaks would be...
So, for the Rx signal I need to choose a window size (like you said, say, 128 samples) and calculate a moving/block average, multiply it by a constant like, say...
Very interesting - all at analog level?I'm sensing that this could be a hint for me?
So, the following are the details of the input signal vectors (all from files of length 8 seconds, mono channel and sampled with a rate of 8 kHz):y1 - the original...
Yeah right? I too thought so. But when I analyse it - it's amplitude is lesser than the original speech file male_8k.wav and it's gain level is also less, -68dB...
I have been experimenting with cross-correlation function to verify the presence of speech in a recorded file wrt a source file. I tried the following in Matlab:source...
