Which Audacity effect is best to raise audio volume

The best effect in Audacity to raise the audio volume level. There are a couple of ways, but does that make any difference? You will find that answer in this Audacity video.

The best video so far on volume on audacity. If I’m doing voice over for my YouTube channel what number should I put my normalize peak amplitude as ?

How do you alter volume setting while recording from a digital source, soundcard? In WASAPI

Am I able to isolate the vocals and amplify just them?

Allow me to introduce a new unit of measurement for sound volume,
which I call vovol* (abbreviated: volume voltage).

THIS IS HOW IT WORKS: You use two pre-stages, one with positive volume values, and the other negative.
For example, so has the pre-step with positive values
a measurement from +0 decibels up to +20, while the one with negative values, has from -0 decibels down to -20 decibels.

The highest voltage occurs when the value is
+20 and -20 decibels (or: 20 vovol),
while there is low voltage, when the value is on
+0 and -0 decibels (or: 0 vovol).

You can possibly also combine two different values with each other, by adjusting the value to +10 -20 vovol, which gives a crisper effect. Have experimented with this myself at work and at home.
The adjustment can of course be set to taste.

More information about Vovol:

When the sound has high volume voltage, the speaker membrane is stretched like a guitar string, so that the sound becomes more sharper, realistic and noise-free.

This can be achieved by using an equalizer with a preamp. First, all frequencies are lowered, to, for example, -12 decibels.
Then you raise it up to +12 decibels, with a preamp.

This is how I usually experiment, with vovol, because currently there are no tools, or apps, to do this.

If you, or other who reading this, have an equalizer with a preamp, I think you should try it too.

And thank you all for reading!

Great video!

Normalize mess the : stereos ( if you not cfg right destroy the stereos ), flat all peeks, if normalize and amplifier was the same wouldn't need two concepts .
Amplifier let the wave peeks same just high respectively your choose .
Definitely don't do the same thing .
