Recordings can be analog or digital. Analog recording captures sound waves on a medium like a phonograph. Digital recording converts sound to a series of numbers and stores it digitally. Recordings are used in education for speech practice, drama, and music. They allow replaying lessons and come in formats like tapes, records, and CDs. The recording process involves capturing sound, converting it to numeric format, storing it, and reconverting playback. Recordings provide a safe, easy way to store information but overuse can bore students.

2.  is a process of capturing data or translating
information to a format stored on a storage
medium often referred to as a record.
 is an electrical or mechanical inscription and
re-creation of sound waves, such as spoken
voice, singing, instrumental music, or sound
effects.

3.  Ways of recording text suitable for direct reading
by humans includes writing it on paper. Other
forms of data storage are easier for automatic
retrieval, but humans need a tool to read them.
Printing a text stored in a computer allows keeping
a copy on the computer and having also a copy that
is human-readable without a tool.

4.  Recordings includes tapes, records, and
compact discs. Tapes may be in form of teacher-
recorded, student-recorded or ready-made tapes
that are commercially produced.
 Audio media are used by teachers in connection
with speech rehearsals, drama musical
presentation.

5. Two main classes of sound
recording technology
1. Analog Recording- is achieved by a small
microphone diaphragm that can detect
changes in atmospheric pressure (acoustic
sound waves) and record them as a graphic
representation of the sound waves on a
medium such as a phonograph (in which a
stylus senses grooves on a record).
- A process with a bigger loudspeaker diaphragm
causing changes to atmospheric pressure to
form acoustic sound waves.

6. 2. Digital Recording- converts the analog sound
signal picked up by the microphone to a digital form
by a process of digitization, allowing it to be stored
and transmitted by a wider variety of media.
- stores audio as a series of binary numbers
representing samples of the amplitude of the audio
signal at equal time intervals, at a sample rate so fast
that the human ear perceives the result as
continuous sound.

7. - digital format can prevent much loss of quality found in
analog recording due to noise and electromagnetic
interference in playback, and mechanical deterioration or
damage to the storage medium.

8. PROCESS
 Recording
1. The analog signal is transmitted from the input
device to an analog-to-digital converter (ADC).
2. The ADC converts this signal to a series of binary
numbers. The quantity of numbers produced per
second is called the sample rate.
3. These numbers are stored onto recording media
such as magnetic tape or hard drive or optical
drive.

9.  Playback
1. The sequence of numbers is transmitted from
storage into a digital-to-analog converter (DAC),
which converts the numbers back to an analog
signal.
2. This signal amplified and transmitted to the
loudspeakers or video screen.

10.  Easy to operate
 Safe way of storing information
 Can be used for big or small groups
 Best used to improve speech skills
 Lessen distraction when used with headphones.

11.  Extended use may bore students
 Costly compared to actual oral presentation
