- Description
- A lossy file format used to compress speech in Global Standard for Mobile (GSM) telecommunications. It is very effective for reducing audio file size. However, encoding and decoding audio signals severally is discouraged as the final product will have a lot of noise. Popular with some voice mail software but it is CPU intensive.
- An RTF file is a common text file format that supports "rich text." It includes several types of text formatting, such as bold type, italics, different fonts and font sizes, and custom tab settings. RTF files also support objects and images, such as .JPG and .PNG files, saved within the text file.
