Explanation:
Detailed explanation-1: -Compression algorithms preserve audio data so the audio is the same as the source. This differs from lossy audio formats such as AAC, MP3, and WMA, which compress audio using algorithms that get rid of data. Audio files are created by silences and sounds.
Detailed explanation-2: -Lossy compression results in a significantly reduced file size (smaller than lossless compression), which is its most noteworthy benefit. It is supported by many tools, plugins and software products that let the user choose their preferred degree of compression.
