basebandaudio

Baseband audio refers to the raw, uncompressed audio signal that is transmitted or processed by a device. It is the fundamental audio data before any modulation, encoding, or compression techniques are applied for transmission or storage. In essence, baseband audio is the pure sound information itself.

This raw audio signal is typically represented as a series of amplitude values over time. When discussing baseband audio, it's important to distinguish it from processed or modulated signals. For example, in telecommunications, the voice signal captured by a microphone is baseband audio. This baseband signal is then modulated onto a carrier wave for transmission. Similarly, in digital audio systems, the uncompressed data stream representing the audio is the baseband audio.

The characteristics of baseband audio include its bandwidth, which determines the range of frequencies it encompasses, and its sampling rate and bit depth in digital systems, which define its fidelity and resolution. Understanding baseband audio is crucial for comprehending various audio processing, transmission, and reproduction technologies. It forms the foundation upon which more complex audio systems are built.
