A chip called an Analogue to digital converter (ADC) is used to convert sound waves in the form of analogue electrical impulses, into numeric values which can then be processed by the computer.
Conversely, a chip called a digital to analog converter (DAC) does the reverse.
The quality of the sound recorded is goverend by two constants , this is the sample rate and the bit depth.
The sample rate is the number of samples of a sound taken per second. For instance a CD is sampled at 44kHz or 44,000 samples per second.
The bit depth describes the maximum value of a number used to store the amplitude of a sound. The greater this value the greater the change between silence and the maximum sound value stores or greater dynamic resolution. In the case of CD's 16 bit or a value between 0 and 65535.

LaoDigitized sound involves converting analog sound waves into binary code that can be stored and transmitted digitally. This process typically involves sampling the analog signal at regular intervals (sampling rate) and quantizing the amplitude of each sample (bit depth), resulting in a series of numerical values that represent the original sound wave. The digital signal can then be stored, processed, and converted back into analog form for playback.

How is sound digitised?
Sound is digitized through a process called analog-to-digital conversion. This involves capturing the sound waves using a microphone, converting them into electrical signals, and then sampling and quantizing these signals into discrete numerical values that can be stored and processed digitally. This results in a digital representation of the original sound.
What are the parts of voice mechanism?
The voice mechanism consists of three main parts: the lungs, which provide air for sound production, the vocal cords, which vibrate to produce sound, and the resonating chambers in the throat, mouth, and nose, which shape and amplify the sound.
What converts your voices sound waves to digital signals?
A microphone converts voice sound waves into electrical signals, which are then digitized by an analog-to-digital converter (ADC) to produce digital signals. These digital signals can then be processed and transmitted digitally.
Why is a sound made every second?
A sound made every second could be due to a repeating event occurring at regular intervals. This could be caused by a mechanism triggering the sound every second, such as a timed alarm or a metronome.
How is sound produced by a keyboard?
Sound on a keyboard is produced when a key is pressed, which triggers a mechanism that strikes a string or activates a digital sound sample. The vibration produced from this action is then amplified through the keyboard's speakers or connected to an external audio system.
