What would make an audio file sound louder?

Question

im not talking about the volume

is there a change if i change the audio codec or audio bitrate?

Answer 1

Changing audio codecs and bitrates only changes your quality of the audio file, not the volume. The best thing to do is to download a sound editing program, for example: Acoustics Mp3 Audio Mixer. Its great for standard users. Increase the volume of the song itself to lets say around 150% (thus you are getting a 50% volume boost compared to the original). Then save it as a mp3/wma (whichever one u prefer) file.
