Äänenkorjaus

Äänenkorjaus, often translated as audio correction or sound adjustment, refers to the process of modifying sound signals to improve their quality, clarity, or aesthetic appeal. This can involve a wide range of techniques applied to recorded audio, live sound reinforcement, or even within musical instruments themselves. The primary goal is typically to address undesirable characteristics of the sound and enhance its desirable qualities.

In the context of audio production and engineering, äänteenkorjaus commonly involves equalization (EQ), which adjusts the balance of different frequencies. This can be used to reduce muddiness, boost clarity, or shape the tonal character of a sound. Other common techniques include compression, which reduces the dynamic range of a signal to make it more consistent, and noise reduction, which aims to eliminate unwanted background sounds like hiss or hum.

Beyond technical adjustments, äänteenkorjaus can also encompass artistic manipulation. This might involve adding effects such as reverb to create a sense of space, or delay to produce echoes. In vocal processing, it can include pitch correction to ensure notes are in tune. The specific methods and goals of äänteenkorjaus vary greatly depending on the source material, the intended application, and the desired final outcome, whether it's for music, film, broadcasting, or public address systems.
