8. Ways to Store Audio Information
Tape
The magnetic tape on
which sound can be
recorded
CD (Compact
Disc)
a plastic-fabricated, circular
medium for recording, storing,
and playing back audio, video,
and computer data
9. Ways to Store Audio Information
USB Drive
an external flash drive, small
enough to carry on a key ring,
that can be used with any
computer that has a USB Port
Memory Card
- is a small storage medium used to
store data such as text, pictures, audio,
and video, for use on small,
portable, or remote computing
devices.
10. Ways to Store Audio Information
Computer Hard Drive
Secondary storage
devices for storing
audio file
Internet or Cloud
websites or file repositories for retrieving
audio files, and more precisely the files
are stored in some datacenter full of
servers that is connected to the Internet
12. MP3 (MPEG Audio Layer 3)
- a common format for consumer audio, as
well as a standard of digital audio
compression for the transfer and playback of
music on most digital audio players.
13. - An audio coding standard for lossy digital audio
compression. Designed to be the successor of the
MP3 format, AAC generally achieves better sound
quality than MP3 at a similar bit rate
M4A / AAC (MPEG4 Audio / Advanced Audio Coding)
14. - is a Microsoft audio file format
standard for storing an audio bitstream
on PCs. It has become a standard file
format for game sounds, among others
WAV
15. WMA (Windows Media Audio)
- is an audio data compression
technology developed by Microsoft and
used with Windows Media Player
23. 1. Mixing – the combination, balance, and control of multiple sound
elements.
2. Pace – time control, editing, order of events
3. Stereo Imaging – Using left and right channels for depth. This
refers to the aspect of sound recording and reproduction.
4. Transition – how you get from one segment or element to
another
24. 1. Segue – one element stops, and the next begins (“cut” in the film).
2. Cross-fade – one element fades out, the next fades in, and they overlap on the
way
3. V-Fade – the first element fades to inaudible before the second element begins
4. Waterfall –As the first element fades out, the second element begins at full
volume. Better for voice transitions, than for effects
25. Accessibility:
For individuals with visual
impairments, audio media provides a
means of accessing information and
entertainment that might otherwise be
difficult or impossible to obtain..
Convenience
Audio media can be enjoyed on
the go, making it a popular
choice for people who are
commuting or traveling.
Emotional Impact
Music and other types of audio
media can have a powerful
emotional impact on listeners,
evoking a wide range of feelings
and memories.
Educational Value
Audiobooks, podcasts, and
other types of audio media can
be a valuable source of
information and education on a
variety of topics.

Quality control:
• Ensuring that audio recordings are of high quality
and free from errors or technical issues can be
difficult.
Copyright issues:
• Audio media is subject to copyright laws, which
can make it difficult to use or distribute certain
types of content.
Language barriers:
• Audio media that is recorded in a particular
language may be inaccessible to those who
do not speak that language.
