Single Channel (Mono) refers to audio that is delivered through a single channel, meaning all sound is mixed together and played back through one output. This format is commonly used in older recordings, radio broadcasts, and some basic audio devices. Mono sound does not provide a sense of directionality or spatial separation, as all audio elements are combined into one track. In contrast to Stereo audio, which uses two channels to create a more immersive listening experience, mono is simpler and often more straightforward. Mono recordings can be beneficial in situations where clarity and intelligibility are prioritized, such as in speech or podcasts.
