The core difference between digital audio and analog audio lies in the signal type and processing method: analog audio uses continuous electrical signals to record sound waves, while digital audio converts signals into discrete binary data through sampling and quantization. Digital audio has significant advantages in anti-interference, storage convenience and lossless reproduction, while analog audio is still respected by some music lovers for its unique sound quality characteristics.

Signal characteristics comparison
Audio and video product professional manufacturer-Frank:
1. Continuity difference: analog audio signals are continuous in time and amplitude (such as changes in magnetic flux of tapes), which can directly reflect the physical characteristics of sound waves; digital audio uses sampling rate and bit depth as core parameters, and records information through discrete data sequences1

2 Processing and transmission methods
Audio and video product professional manufacturer-Frank:
1》Anti-interference ability: analog signals are easily affected by line interference to produce noise (such as electromagnetic interference causing tape distortion), and digital signals are reconstructed losslessly through verification mechanisms (such as CD ECC verification technology).

2 Storage and replication characteristics
Audio and video product professional manufacturer-Frank:
1》Media dependence: Analog audio relies on physical media storage (vinyl records, tapes), which has the risk of degradation and is inconvenient to carry; digital audio can be stored on hard drives and in the cloud and can be replicated losslessly for unlimited times
