Music drowning out singing

If it was recorded with one microphone, there is no good way to rectify this problem. Vocals and guitars share the same frequencies, so EQ is out of the picture. Sorry.

How do you convert sound decibel (dB) measurements to a common loudness scale?

If a speakers specification says it is a 30 Watt speaker, why can’t the formula for decibels be used to convert the 30 watts to dB?

There is at least one more specification needed: effiency also known as sensitivity. Converting electricity to sound is very ineffecient. Typical values of sensitivy is around 90dB sound level for 1 W ...
