the test signal, or even the music coming from the performers in real time. Pink noise is still used by audio system contractors and by computerized sound systems which incorporate an automatic equalization feature. In manufacturing, pink noise is often used as a burn-in signal for audio amplifiers and other components, to determine whether the component will maintain performance integrity during sustained use. The process of end-users burning in their headphones with pink noise to attain higher fidelity has been called an audiophile "myth".
