d.) Lossless and lossy audio files and normalization

Lossless Audio Files: are digital audio recordings that are compressed without discarding any of the original audio data, ensuring that playback sounds identical to the original source.

  • Examples:
    • FLAC
    • ALAC
    • WAV

Lossy Audio Files: are compressed audio formats that reduce file size by permanently discarding some audio data, resulting in a loss of audio quality compared to the original.

  • Examples:
    • MP3
    • AAC
    • WMA

How normalization is different than compression:

  • Normalization is different than compression because it adjusts data to bring it to a common scale or range, often within a specific boundary or distribution. Compression reduces the dynamic range of data, the difference between the loudest and quietest parts.
