COMPRESSION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these are Lossy file type.
A
MP3
B
FLAC
C
Audio
D
None of the above
Explanation: 

Detailed explanation-1: -MP3 (MPEG-1 Audio Layer III) is the most popular of the lossy formats. MP3 files work on most devices and the files can be as small as one-tenth the size of lossless files. MP3 is fine for the consumer, since most of the sound it drops is inaudible, but that’s not the case when it comes to bit depth.

Detailed explanation-2: -MP3 uses two compression techniques to achieve its size reduction ratios over uncompressed audio-one lossy and one lossless. First it throws away what humans can’t hear anyway (or at least it makes acceptable compromises), and then it encodes the redundancies to achieve further compression.

Detailed explanation-3: -Lossy Compression is when data is lost or quality is reduced from the original version while compressing data. Lossy compression is typically associated with image files, such as JPEGs, but can also be used for audio files, like MP3s or AAC files.
