Lastly, we have an option that allows us to normalize the stereo channels independently. This can have serious consequences during editing. This solves a problem that sometimes happens when we digitalize sounds – when the center of the sound wave doesn’t match with the “zero” point of the recording, and it’s placed incorrectly at a higher or a lower point instead. The upper one says, “Eliminate DC offset”. Let’s see the other two options that the Normalizer offers. Exactly the same as if we had done it with the Amplify tool. The basic one is in the middle: we set an amplitude peak, just like we did in the amplitude window.Īnd Audacity will modify the level of the selected audio evenly, so that it reaches the desired peak without surpassing it. We have a window with three options that can be activated. It essentially does the same: it raises or lowers the level of the recording.īut it’s presented in a different way. The “Normalize” tool is very similar to the Amplify one. This security measure is turned off when we activate “Allow clipping”.
Thus, it will only allow us to amplify the sound if we don’t deteriorate the sound. If it’s not on, we won’t have the option to click on accept when the maximum peaks value is positive. To prevent this level from going over 0db by accident, there’s an option called “Allow clipping”. When we move the slider, the value of the highest amplitude varies. When we’re working with digital recordings, any peak that goes beyond 0db will not be recorded as such, instead, it will be clipped, and the result, will be a deteriorated sound quality.
This tells us the highest value that the audio will reach in its peaks. Right under it, we have a small text box where we can see the maximum amplitude peak that corresponds to our selection. We click on Effects, Amplify.Ī small window appears, with a slider that allows us to indicate by how many decibels we want to increase our audio level. Let’s suppose that we want it to be registered louder. We have loaded one audio file in Audacity as an example. Lets check them out in the Audacity Tutorial Guide for Beginners: How to Control the Level There are two basic tools for this: amplification and normalization.
