What audio processing technique is most effective at controlling the dynamic range of a vocal track?

The audio processing technique most effective at controlling the dynamic range of a vocal track is compression. Compression reduces the difference between the loudest and quietest parts of an audio signal. It works by automatically reducing the gain (volume) of the signal when it exceeds a certain threshold, which is a set level. The amount of gain reduction is determined by the ratio, which specifies how much the signal is reduced for every decibel it exceeds the threshold. For example, a ratio of 4:1 means that for every 4 dB the signal exceeds the threshold, the output level is only increased by 1 dB. This makes the louder parts of the vocal track quieter, while the quieter parts remain relatively unchanged. This results in a more consistent overall volume level, making the vocal track easier to hear and preventing it from being too loud or too quiet at different points. A compressor also has settings like attack and release, which control how quickly the compressor responds to signals exceeding the threshold, and how quickly it stops compressing after the signal falls below the threshold. Proper use of compression can make a vocal track sound more professional and polished.
