COMPUTER 101: AUDIO

If you have used computers for a while you know this, if you are fairly new to computers, this may help you. 

This is a computer 101 lesson, which will hopefully give you some more information that will enable you to understand what is going on with and in your computer in regards to emcee pro and how emcee pro works with your computer.

There are a handful of audio file types you should be familiar with if you are planning to copy music off the Internet or even copy a CD. If you aren't sure what file types you are working with, you can distinguish any file type on your computer by the extension in the file name. The extension is the set of letters that follows the dot.

File extension or filename suffix is usually three or more letter codes or numbers at the end of computer file name. This extension tells the computers operating system (Microsoft Windows 7, Windows Vista, Windows XP, Windows 95/98/ME/2000, operating systems etc.) what kind of data file they are dealing with. File extension tells to operating system which software program can open or edit the file.

1.     Waveform Audio (.wav)

Waveform Audio (.wav) is a common file format. Created by Microsoft and IBM, WAV was one of the first audio file types developed for the PC. WAV files are defined as lossless, meaning that files are large and complete; nothing has been lost.

The three file formats below must begin with a lossless format-such as a store-bought CD or a computer WAV file-then compress it. Most lossy formats boast little or no detectable change in sound quality. But because each compressing format selects the deleteable data differently, converting one compressed file into another lossy format will sometimes result in lower quality audio. Again, always start with a CD or WAV file, then compress.

2.       CD Audio Track  (.cda)      

Professionally recorded CDs are also a lossless audio source. In contrast, the audio formats listed below are lossy-redundant and non-auditory data is removed to allow for more compact storage.  This process of removing data to shrink the file size is called compression.

3.     MPEG-1 Audio Layer 3 (.mp3)

MPEG-1 Audio Layer 3 (.mp3) is a common, compressed WAV file. MPEG-1 files are about one-twelfth the size of WAV files. This is why MP3 players can accommodate hundreds of songs on a tiny chunk of storage space.

4.     Windows Media Audio (.wma)

Windows Media Audio (.wma) was developed to compete with the MP3 format for Windows Media Player. Microsoft claims that the WMA files are compressed three times more than MP3s yet retain their original sound quality.

Now with the above information digested, I will take the explanation several steps further.

You can get music onto your computer’s hard drive in several ways. 

  • Use Windows Media player (download or extract or rip)
  • Use a Flash or thumb drive (copy)
  • From the internet (Download)
  • Use EmceePro (extract)

If your music is on a CD Audio Track  (.cda)   Professionally recorded CDsyou must RIP or EXTRACT the music. You can use Windows Media player or Emceepro

If your music is on the internet, you have to DOWNLOAD.

If your music is on someone else’s computer, or flash drive, you must COPY and then PASTE to the place in your computer you wish to have the music. Learn how to navigate using your windows explorer.

It's really fast. Try it now.
