Question 1

My recording is too quiet. What should I do?

Accepted Answer

Turn on "Auto level" — the volume is raised as high as possible without distortion.

Question 2

Why does it crackle when I turn it up a lot?

Accepted Answer

When sound goes past the maximum, the peaks are cut off and it distorts. Lower the level or use "Auto level".

Question 3

Is it free? Do I need an account?

Accepted Answer

It is completely free and needs no sign-up.

Question 4

How much louder can I make it?

From 10% to 300% of the original volume; 100% keeps it as it is. If you are not sure which level to pick, turn on "Auto level".

Can I adjust several files at once?
