Audacity compressor and Audacity normalize are both use by sound editors to increase audio track volume. Now, go to File > Export Audio and export your merged audio file. Normalization of the data allows us to get experience with step sizes and use systematic weight initializations. ogg But why don't you use replaygain (mp3gain/vorbisgain) instead of normalize-audio? Difference is that normalize-audio will re-encode the audio files and you'll lose quality. Normalization is one of the functions commonly provided by a digital audio workstation. Sound Grinder is great for file conversion, and summing split mono files and it also has a normalize feature but I think it only does peak normalizing. This is another term for normalization and is very similar to the Sound Check feature in iTunes. We had no idea extracting audio from a video files using Audacity would be so easy.
