Increasing Volume Issues

This is on Windows 7, Audacity 2.1.2
Hello everyone, I’ve been looking into this for a while and I can’t seem to find any solutions anywhere.
I have noticed that when I upload any of my songs to Soundcloud, they are significantly quieter than other songs by other artists. I was trying to increase the volume of my song, but I could not find a way to do this without clipping and the bass becoming distorted. However, if I increase the volume manually on my computer, just turning it up, no clipping occurs and everything is fine. I was wondering if there was a way to make this increased volume the start volume of my track, without having any clipping or bass distortion occur. I hope I explained this well enough and thanks for any help you can give.

Try the compressor effect or the limiter effect (set to hard limit), both with make-up gain to bring-up the overall volume, or instead of make-up gain, you can re-normalize or re-amplify after compression/limiting. I’d say start with the limiter set to about -6dB to see what that does for you.

Dynamic compression is an art so it will take some experimentation (and there are no "easy fix-all presets) and you are unlikely to get “loudness” equal to a modern, professionally-mastered song. And if you over-do it, the whole song will be constant-loudness with no dynamic contrast and you can get distortion. (See [u]The Loudness War[/u].)

Try Audacity’s (soft) limiter with make-up gain, see …

Alright thanks guys, I will try these out.
