Join Garrick Chow for an in-depth discussion in this video Using compression, part of Up and Running with Audacity.
If you don't have much experience working with audio, you may wonder what makes a professional…recording sound so different than one you record at home.…Well, obviously there are a lot of factors like the quality of your recording space, your…microphones, and so on.…But one characteristic that gives a recording a more professional sound is compression.…Raw audio recordings generally don't have a uniform volume level.…Some sections are louder than others and some sections are quieter.…When listening back to some recordings, you might feel like you have to constantly turn…the quieter parts up and the louder parts down.…For example, look at the waveform for this file I have opened.…
Even before I play it you can tell that some parts are louder than others.…I'm going to make this track little bit taller so you can see the difference better.…Now before we listen I'm going to drag the level meters out on their own and I'm going…to make them vertical.…This will make it easier to see how loud the loudest parts of the recording are.…
