normaliserĪ normaliser adjusts the highest volume to a level - it does nothing to the dynamic range. Explosions hurt your ears, but turning it down so the explosions are listenable means you can't hear dialog.) and will always sound better than a temp.
Leveller is useful in Audacity for things that aren't vocals that need less dynamic range (i.e. For a vocal track or a podcast, it is basically essential, as it evens out variance in spoken volumes, which has the neato side-effect of making all talking pretty much the same volume. normaliser, I guess, and you'd get nicer sounding results, but I would never actually use it for a whole recording. You could use this for the same thing as the temp. It isn't useful if a stream isn't live, because it will not sound as good as compressed stuff.Ī compressor on the other hand, takes a signal and can then be told to reduce the dynamic range of a track (actually altering the audio to make the louder parts and quieter parts closer in volume) behaving according to set parameters. I use it via mplayer for a few select films. This is surprising useful for live streams that have huge dynamic ranges that you want to listen to at home as it'll go quieter when too loud and louder when too quiet. Kdenlive uses a temporal normaliser (in my opinion calling it a normaliser isn't useful - call it tempvolnorm or something), which just means that it turns it up or down based on the weighted average of the samples around it (I don't think it uses read-ahead).
