There are several methods for producing and capturing sounds, including audio recording and reproduction techniques as well as obtaining sounds from the web. Audio can be recorded using both analog and digital methods. Analog recording stores audio as a continuous wave in a medium, such as using early phonographs, wire recordings, or magnetic tape. Digital recording converts analog sound waves into a stream of discrete numbers through techniques like pulse code modulation, allowing for clearer reproduction of sound.

3. Different Methods of Producing Sounds
• Audio Recording and Reproduction
• Ripping CD Tracks
• Sounds from the Web
4. Audio Recording and Reproduction
• This involves the electrical and mechanical capturing and creation
of sound waves with the use of different audio devices.
• There are two main classes of audio recording.
• Analog recording
• Digital recording
5. Analog recording
• A method of storing audio and video signals as a continuous wave
in the media for later playback.
• In 1877, Thomas Alva Edison, the American inventor of the
phonograph, successfully demonstrated the use of analog audio
recording.
• There are various ways of recording audio.
• Gramophone or phonorgraph recording
• Wire recording
• Magnetic tape, Magnetic sound recording
6. Gramophone or phonograph recording
• It is a device created by, Emil Berliner in 1887 which was based on
Edison’s original phonograph
• It used a diaphragm directly controlling a needle, which scratches
an analog signal into a tinyfoil cylinder.
• This was then improved using flat records with a spiral
groove, which resulted to a greater number of recorded outputs.
7. Wire recording
• Makes use of a thin steel or stainless steel wire for storing audio.
• 1890s, the first wire recorder, the Valdermar Poulsen Telegraphone
was made.
• It was used as substitute for commercial office dictation
recorders.
8. Magnetic tape/Magnetic tape sound recording
• Uses magnetic tape for storing audio
• Consists of a thin, magnetisable coating on a long and narrow strip
of plastic
• Was initiated by Oberlin Smith in 1877
• Demonstrated in pactice in 1988 by Valdemar Poulsen.
9. Digital recording
• Handles analog sound and converts them to a stream of discrete
numbers in a specific period of time
• Developed by Max Mathews on Bell Telephone laboratories in 1957
• Other advancements in digital electronics and microchips led to
the development of the first digital Pulse Code Modulation (PCM)
audio recoder in 1967
