What is sound?

• is a form of a mechamical wave that propagates through a medium typically air but it can also travel through liquid and solid

• audio also a sound but mostly in the context of its recording, reproducing or transmission

• process by which sound information is captured onto a storage medium

• refer to a process of capturing and storing moving images in digital or analog format

common bit dept in digital audio.

• 16 bit

• 24 bit

• 32 bit

• 25 bit

What is the measured of sampling rate?

meaning of sample rate.

• is a crucial parameter in digital audio processing that determines how often an analog audio signal is sampled or measured per unit of time.

• is a form of mechamical wave that propagates through a medium typically

What is the definition of audio sampling?

• It is the process of converting sound waves into digital format by measuring the amplitude of the sound wave at regular intervals.

• It refers to the process of recording and storing audio signals in analog format.

• It is the method of compressing audio files to reduce their size without significantly affecting the quality of the sound.

Explain the concept of frequency in relation to sound waves.

• It refers to the number of complete cycles of a sound wave that occur in a second, measured in Hertz (Hz).

• It is the measure of the loudness or softness of a sound, often described as high or low pitch.

• It is the process of converting analog sound waves into digital format for storage and processing.

What is the role of a microphone in capturing sound?

• It converts sound waves into electrical signals that can be stored, transmitted, or processed.

• It amplifies the sound waves to make them louder and clearer for recording or broadcasting.

• It filters out background noise to ensure that only the desired sound is captured.
