Exciter

An exciter is a device used in audio and radio systems to enhance sound quality. It works by adding subtle harmonic details and boosting certain frequencies, which makes the audio sound brighter, clearer, and more lively. Think of it as a way to inject warmth and presence into the sound without changing the overall tone too much. Exciters are commonly used in music production, broadcasting, and audio mastering to improve how audio signals are perceived, making them more engaging and full-bodied.
