What is an expander in audio?

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. Upward expanders boost the level of an audio signal above the threshold, making loud sounds even louder.

What is upward and downward compression?

Downward compression reduces the volume of loud sounds above a certain threshold. Upward compression increases the volume of quiet sounds below a certain threshold. The louder sounds above the threshold remain unaffected.

How do I increase the volume on my voice recording?

Workaround

1. Click Start , and then click Control Panel.
2. Click Hardware and Sound.
3. Under Sound, click Manage audio devices.
4. Click the Recording tab.
5. Click the microphone device, and then click Properties.
6. Click the Levels tab. Move the slider to increase or decrease the volume.

What is audio peaking?

This is distortion caused by speaking or screaming too loudly for the poor, sensitive microphone. The wave form goes vertically right out of the box.

What is expansion and compression?

Compression is a process under which volume of the system is gradually reduced, pressure and temperature increases where heat transfer may or may not be possible. While in expansion process volume is gradually decrease with the decrease in pressure and temperature and heat transfer may or may not be possible.

What is audio compression expansion?

Audio expansion means to expand the dynamic range of a signal. It is basically the opposite of audio compression. Whereas compression and limiting take effect whenever the signal goes above the threshold, expansion effects signal levels below the threshold.

Where should audio levels peak?

For safety, no peaks should be above -6db. Most video editors agree that the overall audio level of your audio mix (all of your audio combined) should normalized between -10db to -20db. I personally level my videos around -12db with occasional peaks to -8db. The trick here is to stay away from 0db as best you can.

What is digital audio clipping?

Clipping audio is when an audio signal is amplified past the maximum allowed limit, whether in a digital or analog system. This is called ‘overdrive’ and just like the guitar pedals with the same name, it leads to distortion and a lowering of audio quality.

What is expander plugin?

Expanders increase the difference in loudness between quieter and louder sections of audio making quiet sounds quieter and loud sounds louder. A side effect of expanders is that they change the way sounds decay and can end up silencing quieter parts of your audio that you want to keep.
