i want the music to be at a higher volume
so i should make the vibrants higher so it will have a bigger volume?
and also if i do that will it also affect the quality
There is what I
would call a glitch with Audacity to allow you to infinitely adjust your music volume. If you use the envelope tool and make sure the volume is expanded to the max, be sure to test it. If you hear static or abrupt speaker blows, nerf the envelope. Get it just right and you can manage to get the music louder without it sounding like static stuff.
To exceed the EnvelopeI call this a glitch but some people might call it a feature. When you reach the max of the envelope, and the music STILL sounds too low without speaker blows, export the selection, and paste it to your desktop (It's what I do). Next, you want to put that SAME file you pasted onto your Desktop right back into audacity. This will now reset the envelope to where you saved it but will act like the envelope was never touched. In english, it means you have louder volume and can make it more loud.
