Speech Compression

Notes de l'éditeur

  1. Hello, Today I will talk about the common techniques commonly used for digital audio compression of various audio filetype formats.
  2. -I will discuss the difference between redundant and irrelevant further in my presentation. -Depending on storage or transmission, there is an optimization in size
