1. Basics of sound recording:
When recording a sound using
electronic devices you will have a
high noise ratio, it is very likely
that you will have analogue
distortion, and digital distortion.
Mono: This means that there would
only be one type of recording
equipment for example you may
only have one microphone or one
speaker.
Stereo: This means that there
would be more than one speaker
or microphone present when the
recording will take place.
When recording onto a sound you
will use a digital audio file to
record on they will have certain
formats e.g. .mp3, .wav, .mid, .ogg,
.wma, .aif
Analogue versus digital:
Comparison of analogue and digital
sound: Analogue sound uses lest
bandwidth and is more accurate
with the recording making the
sound stronger and easier to hear
and develop. Digital sound
however is more reliable, flexible
and connects well when you use
other digital.

2. Sound in the interactive media
Applications:
Interactive media products
CD- This is a compact disc which
stores information; it can store
items such as music or pictures. It
was first developed to play back
sound recordings but was after
adapted to store data. The data on
the CD can be something such as
Music this music can be used in
any device that would allow a cd
to be played, the music on the
device can be anything that is
downloadable. This is mainly
used for entertainment but can be
used to transfer important music
files or photos;
DVD interface- Within the media
there is a concept in which two
components; this can be
conducted by using something
small like an SD card or
something as big as the internet.
The data can be used to hold
music, photos or moving images
and can be played in any device
that is DVD compatible. This is
mainly used for entertainment
but in some cases can be used to
transfer important data.
Television- This is a telecommunication
device in which you can transmit
moving images or sound recordings
such as radio. The sound recordings
used on a telecommunication device can
show the emotion of the characters in
the television show, for example if the
character in the TV show is sad, sad
music will be played to show that the
character is sad.
Mobile phone content- This is a device
that can be used to make and receive
phone calls, this is a device that uses the
sound waves across a signaled path so
that the person on the other end of the
phone line can hear what the first
person is saying.
Pitch- Pitch is where the ordering of the
sound is related on the frequency scale.
Pitches are compared as ‘higher’ and
‘lower’ Pitch is a major attribute of
musical tones, duration, and loudness.
Decibel level (dB) - The decibel (DB) is a
unit that indicated the ratio of quantity.
A decibel is one tenth of a bell.
The rate at which a sound wave moves
is called the frequency. Frequency is
measured Hz. The length of a single
cycle of a waveform is the span of time
it takes for that waveform to repeat.

3. Sound is being used in almost every single electronic device. Toys, video
games, music, television, appliances, cars and many more. They are not all
placed there for entertainment purposes. Houses and cars appliances can
indicate when something is wrong and produced a sound so we can all be
alert and aware. A great example of this is a smoke alarm.
Sound within video games is updating frequently and is becoming more
and more creative with the use of the newest technology. In these videos
games nowadays the graphics are on point, sound tracks used are in the top
charts to apply to mainstream audiences and SFX are so realistic that it
makes you feel like you are there.
Just like video games Television is always being modernized. With Foley
artists and software becoming bigger and bigger anything can be created. A
great example of this would be the film Transformers in comparison to
Indiana Jones.
Pitch
This can also be known as the frequency (again can be known as hertz (HZ).
Us humans can hear between 20 and 20,000 Hz. The lower the Hz the lower
the sound, and again the higher the sound. A single Hertz is one wave cycle
from crest to crest.
