What does an expander plugin do?
Expander is similar in concept to a compressor, but increases, rather than reduces, the dynamic range above the threshold level. You can use Expander to add liveliness and freshness to your audio signals.
What do expanders do mixing?
What are Expanders? Expanders are helpful dynamic processing tools that increase the dynamic range of an audio signal. They are essentially the opposite of a compressor, which decreases the dynamic range of an audio signal.
What is an expander?
An expander, also called a rapid palatal expander or RPE, is an appliance designed to correct a narrow upper arch that can result in crossbite, crowding, or impacted teeth. Two bands are cemented onto the last upper molars and connected by a metal screw that gets turned regularly to expand the appliance.
When would you use an expander?
An expander can be used to achieve the opposite result of a compressor, expanding the dynamic range rather than compressing it. Therefore, expanders are best used when you want to have a wider dynamic range. Expanders can be used to make instrumental or vocal performances a bit more varied in volume.
What do expanders do audio?
What do expanders do? Again, like a compressor “compresses” and a limiter “limits” the dynamic range, an expander expands it. Louder and quieter parts become relatively louder and quieter respectively. As such, it’s essentially the opposite of a compressor.
How do you use an expander?
The bands are placed around the first molars, with an expansion appliance that goes across the roof of the mouth. Use the expander key, insert until it clicks into place and push towards the back of the mouth until the next hole comes up. The expander will have arrows pointing the direction for the expander key.
How does an expander work in audio?
More commonly, expanders are used for noise reduction. In this application (downward expansion), a threshold is set at a level below desired audio signals, but above the noise floor. When signal drops below the threshold, expansion is applied, pushing signal even further down, reducing the level of noise.
Are expanders necessary?
Palatal expanders are necessary to correct skeletal jaw discrepancies. When the upper jaw is more narrow than the lower jaw, your child will have a bite problem. This includes a crossbite on one side or both sides in the most extreme cases. There are legitimate reasons to start your child’s orthodontic treatment early.
What does the expander do audio?
What is an upward expander in audio?
In a standard expander (which is upward), an expansion ratio of 1:x amplifies the signal to a level of x dB above the threshold for every 1 dB it crosses. Again, let’s look at an example. Say we had an upward expander with a ratio of 1:3 and a threshold set at 0 dB.
When to use an expander?
Expanders are also useful when producing voice oversand ADR. Note that an expander isn’t effective when the noise level is almost the same as the dialogue level. In this case, an expander could not differentiate between the voice and the noise. More destructive noise removal tools would be needed here.
What is the best plug-in to expand a stereo signal?
Wizard is a plug-in that expands the stereo image of any mono or stereo signal, in general this is a mono-compatible plug-in, so we avoid some phase problems when summing a mono signal. Nice and simple to use, very effective. Love it.
How do you use an expander on a mic?
An expander can be used, for example, to decrease the volume of the hat in the snare mic. As the hat will be further away from the mic than the snare, it will be quieter than the snare when picked up by the snare mic.
