Study Notes
Transducers in Digital Audio
- A transducer is a device that converts one form of energy into another, such as sound waves into electrical signals.
- In the context of digital audio, a microphone is a type of transducer that converts sound waves into electrical signals.
- The function of a microphone is to capture sound waves and convert them into electrical signals that can be processed and digitized.
Amplitude and Intensity
- In the context of audio, amplitude refers to the magnitude or size of a sound wave, while intensity refers to the power or energy of the sound wave.
- Amplitude and intensity are related, but distinct concepts, with amplitude affecting the loudness of a sound and intensity affecting the perceived volume.
Digital Audio Conversion
- The process of converting sound waves into discrete digital samples is called digitization or sampling.
- This process involves capturing sound waves and converting them into a series of digital values that can be stored and processed by computers.
Audio Signal Properties
- The perceived pitch of an audio signal is related to its frequency, with higher frequencies resulting in higher pitched sounds.
- Transducers like speakers convert digital audio signals back into sound waves, allowing us to hear the audio.
Transducer Functions
- A transducer like a microphone converts sound waves into electrical signals, which can then be digitized and processed.
- A transducer like a speaker converts digital audio signals back into sound waves, allowing us to hear the audio.
