Why isn't the classical guitar part of an orchestra?
There certainly isn't one single reason, and, yes, “that's just how it's always been” is probably an important point.
However, I would quite agree that guitars should not be part of a ...

Why do we need power amplifier with hundred watts of power?
Indeed it's easy to generate very loud noises with a speaker system whose power is only a fraction of what's actually used in PA or HiFi systems. What's not so easy is to get any sound you want to ...

Normalization - peak amplitude level vs actual loudness level
My suggestion is to do three steps. Step one, using your EARS, adjust the volume of the various portions of your program so that they have the correct relative volume that you want. If you want them ...

Relationship between amplitude and loudness (again)?
Amplitude is an objective measurement. In a waveform, it is the value of the y axis at any given point in time.
Loudness is a subjective measurement, based on how we perceive amplitude and other ...

Why do we need power amplifier with hundred watts of power?
Some of that chart isn't very good in my opinion. 85dB isn't that loud. A typical concert will be at 106dB to 110dB or sometimes louder and the power requirement doubles every 6dB or so because it is ...

What defines loudness of mp3 in a file?
Let’s take a CD audio audio stream. It is a stream of 16 bits samples : in an other word, a stream of numbers between -32768 and +32767. On audacity, each number is matched with a number between -1 ...

How do I adjust recorded audio so that the quiet parts become louder and the loud parts become quieter?
This is one reason why a) you do a level check before you go & b) why you record to separate tracks.
If compression/limiting can't make up the gain enough, or over-compresses one voice without ...

Whether the audio file safe for my speaker? How can I know?
No matter what the maximum volume is of the file, your amplifier will have input and output maximum. If the input is too high, your gain stage will clip - generally not pleasant, but it limits the ...

The situation you are describing is where I would use a noise gate. When there is talk going on, the gate opens. When there is no talk going on, the noise gate closes and there will be silence.

You're heading in the right direction. Compression is what you need, though maybe you want more of it.
A 'harder' version of compression is known as Limiting.
