## Re: Is RMS a good metric to estimate gain

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?

## Re: Is RMS a good metric to estimate gain

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...

## Re: Is RMS a good metric to estimate gain

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

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...

## Re: Finding "channel" impulse response from input and recorded data

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...

## Re: Use cross-correlation for speech detection/verification and time delay measurement

Thanks a lot. This helped. Exactly what I wanted to understand regarding the maxLag parameter of xcorr.

## Re: Use cross-correlation for speech detection/verification and time delay measurement

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...

## Re: Use cross-correlation for speech detection/verification and time delay measurement

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...

## Re: Use cross-correlation for speech detection/verification and time delay measurement

Very interesting - all at analog level?I'm sensing that this could be a hint for me?

## Re: Use cross-correlation for speech detection/verification and time delay measurement

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...

## Re: Use cross-correlation for speech detection/verification and time delay measurement

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...

## Use cross-correlation for speech detection/verification and time delay measurement

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...
