As explained in “Audacity Effects: Use of Decibels (Log Scale),” sound is representation better in decibel scale, especially if you want to show volume (amplitude) changes.1 Although Audacity’s default view is in linear scale, most of the effects use decibels … Continue reading
In Audacity, we normalize to a level, but amplify by a level. However, in the “amplify” effect, there is also an option for you to amplify to a chosen peak amplitude. When this option is used, “amplify” basically functions the … Continue reading
In the previous article we talked about “allow clipping” for “amplify” effect. By checking the “allow clipping” option, you allow the signal to be amplified above the maximum level, so distortion or clipping will occur. In this article, we will … Continue reading
When we work with audio in Audacity, we basically work with relative scales. With a particular calibrated system, the linear amplitude of 1.0 (or 0 db in log scale) represents the maximum amplitude before distortion or clipping occurs. While we … Continue reading
The Amplify effect is similar to Normalize effect. Amplify allows you to amplify a track or tracks by a certain level whereas Normalize sets the peak amplitude to a certain level. Optionally, Amplify can also set peak amplitude to a chosen level, in … Continue reading
“Normalize” effect is an effect that sets the maximum amplitude to a chosen level (expressed in decibels). For multiple tracks, “normalize” effect treats each track independently, that is, it will set the maximum amplitude of each track to the chosen level. … Continue reading
In last article, we talked about the effect of “normalize.” Basically, it takes the maximum amplitude of the signal we are processing, adjusts it to the level that we choose and adjusts the whole signal proportionally. In terms of decibels … Continue reading
The normalize effect is a simple effect to set maximum amplitude to a chosen level. If you think of any audio system, be it a simple CD player or a complex sound system with lots of equipments, the normalize effect … Continue reading
Some people might find it strange that dc offset removed is lumped together with normalization effect. The reason is that in mathematics, normalization usually involves offset shifting and re-distributing of data, and dc removal is the offset shifting part. In … Continue reading
Sound intensity is related to pressure, and the unit of pressure is Pascal (abbreviated Pa). However, we don’t normally use Pa in describing sound intensity; we use the unit of decibel (db) instead. It is not necessary to understand all … Continue reading
