Signal Chain
Definition
The complete sequence of devices, processors, and connections through which an audio signal passes from source to destination. The order of elements significantly affects the character and quality of the final sound.
In Simple Terms
The order your audio travels through—microphone, preamp, compressor, EQ, converter, DAW. The order matters enormously. Swap two elements and the same settings can sound completely different.
In Practice
A typical vocal signal chain: microphone → preamp → compressor → EQ → audio interface → DAW, with additional processing applied within the DAW session during mixing.
