3) Audio

Those sound waves which we can hear are called audible or sound. Audio is an integral part of multimedia. The frequency range of an audio signal is from 200 Hz to 3200 Hz, while humans can hear the frequency of 20 Hz to 20 kHz. Audio is an analog signal. This is converted into electronic signals by the microphone.

These electronic signals are converted into digital data and stored in the computer. These are converted into electrical waves for listening to this digital audio. Speakers or headphones convert these electrical waves into analog sound waves that our work can hear. Artificial digital audio data can be generated by computers that we can hear through speakers or headphones. For this, it is necessary to have sound card hardware in the computer. A multimedia computer is capable of generating, recording and playing audio data. Some popular audio file formats are:

  • MPEG – Motion Picture Expert Group Audio
  • mp3 – mpeg audio layer 3
  • WAV – Waveform Audio File Format
  • MIDI – Musical Instrument Digital Interface, etc.

4) Video

A multimedia computer can record, edit, store and play a series of video images that can be viewed on a computer monitor. This requires video card hardware. Nowadays multimedia computers are being used in the field of entertainment for recording videos, viewing video pictures and playing video games etc.

5) Streaming

A file of audio or video data takes up a lot of memory and takes a long time to be downloaded over the Internet. And we can use the downloaded audio or video data only when the file is completely downloaded. Streaming technology is used to solve this problem.

With this technique the audio/video file is compressed so that it occupies less space. Also the file is started immediately i.e. play. While the file is playing, the remaining parts of the file are also downloaded. Thus, there is no need to wait for the entire file to be downloaded to use the file. This is called streaming. YouTube video streaming is the most common example of this.
