There are 2 common types of formats: WAV and MP3. There is no difference in sound between these two, but the difference is a WAV file is uncompressed audio and MP3 is compressed audio. Lossy Compression: CD’s contain uncompressed audio although your brain cannot process all of the different sounds so MP3 compresses the audio by taking the frequencies from the song and throwing away the frequencies the average human can’t hear so there is no difference in the sound, to humans.
Another important thing to know is how to figure out the file size to ensure your files are not to big for the cd or other storage device. Here is how you figure it out:
1) Convert the minutes to seconds. Exp: 8 minutes and 42 seconds à 522 seconds
Note: Stereo sound uses 2 channels or 16 bit DAC (Digital Audio Conversion
2) Figure out the 16-bit number. Exp: Total 16-bit sampled: 522*44100*2=46,040,400
3) Now figure out the 8-bit by multiplying it by 2. Exp: Total 8-bit bytes = 92,080,800 (87.8 MB)
