Compressor
/kəmˈprɛsər/
Definitions
2 meaningsA mechanical device that reduces the volume of a gas (such as air) by applying pressure, thereby increasing its density and often its temperature.
/kəmˈprɛsər/
A mechanical device that increases the pressure of a gas.
The mechanic diagnosed a faulty compressor in the car's air conditioning system.
💡 Simply: Imagine you're inflating a bike tire. The pump, or the part that makes it happen, is like a compressor. It takes air and squishes it into a smaller space to make it strong enough to fill the tire. Compressors are used in things like refrigerators, air conditioners, and even to make air tools work!
👶 For kids: A compressor is like a squishy machine for air. It makes air smaller and stronger!
More Examples
The industrial compressor provides compressed air for operating heavy machinery.
Audio engineers use compressors to control the dynamics of sound recordings.
How It's Used
"The air conditioning system utilizes a compressor to cool the refrigerant."
"Pneumatic tools in the factory are powered by a large industrial compressor."
"The audio engineer used a compressor to reduce the dynamic range of the vocal track."
In audio engineering, a device that reduces the dynamic range of a signal, making louder sounds quieter and quieter sounds louder, or vice-versa, to achieve a desired effect in terms of audio dynamics.
/kəmˈprɛsər/
A device used in audio engineering to reduce dynamic range.
The mixing engineer used a compressor to smooth out the vocal track.
💡 Simply: Imagine a sound being too loud and quiet at times. A compressor is like a volume control that automatically turns down the loud parts and turns up the quiet parts to make the sound smoother and more balanced, so you can hear everything clearly without any sudden loud moments or inaudible soft ones. It's what you'd use to make a song more balanced.
👶 For kids: It's like a sound adjuster that makes the loud parts of a sound quieter and the soft parts louder so you can hear everything.
More Examples
Careful use of a compressor can give a recording a polished, professional sound.
Over-compression can lead to a 'pumping' effect in the audio.
How It's Used
"The compressor helped to reduce the dynamic range of the recording."
From Late Latin *compressor*, from *compressus*, past participle of *comprimere* 'to press together' (com- 'together' + premere 'to press').
The term 'compressor' has been in use since the late 19th century, coinciding with the development of mechanical refrigeration and air compression technologies.
Memory tip
Think of squeezing a sponge – the compressor squeezes gas, making it smaller and more powerful.
