Study Notes
Analogue to Digital Conversion (A2D)
- Computers represent all data, including sound, in binary.
- Analogue sound waves must be sampled and stored as binary for computers to understand and process them.
- The process of converting analogue sound waves to digital is called Analogue to Digital Conversion (A2D).
- A2D involves measuring the amplitude of the sound wave at specific points in time, called samples.
- The higher the amplitude of the sound wave, the louder the sound.
- Each sample generates a value that is represented in binary and stored.
- These samples are used to create a digital representation of the original analogue wave.
- The digital wave is stored on secondary storage and can be played back by reversing the A2D process.
- The sample rate, bit depth and sample interval can be adjusted to create a digital wave that more closely resembles the original analogue wave.
