Compressors are devices that reduce or control levels, whether in sound, gas, or air, by applying pressure. Understanding them is essential because compressors help us achieve consistent and desired results in many fields.In audio, a compressor manages sound levels, keeping the loud and soft parts of a track balanced, so recordings sound professional and clear. In industrial settings, compressors pressurize gases or air, which powers tools, enables cooling systems, and supports various mechanical functions. Familiarity with compressors helps ensure that you can operate them correctly, improve efficiency, and maintain safety in tasks that require controlled pressure or consistent output.
