Description🔵 MKV Matroska is an open-source multimedia container format that supports more than one audio and subtitle tracks in the same file. It is the most convenient file type where you can add a large sum of data, such as videos, audios, texts, and various images. It is a RAW format which you can later flip and separate based on needed data tracks.
Technical details🔵 Whether it is video, audio, subtitle, or image, every file will be stored in a separate data line. It is a lot similar to the MP4 or AVI format, although when users are packaging an MKV file, they rarely bundle all the tracks within the file. Various media players don't even support the MKV video format; therefore, the users need to use specialized media players who can help the MKV format, such as VLC media player.

Description🔵 .mp (MPEG Layer Audio) The .mp format is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a standard de facto codec for the transfer and playback of music on most digital audio players. MP files compress audio data by eliminating sounds that are outside the hearing range of most people, thus reducing the file size without significantly affecting the perceived sound quality.
Technical details🔵 The `.mp3` format, MPEG-1 Audio Layer III, is a popular digital audio format. Here are the key technical details: - Lossy Compression: Reduces file size by removing less audible sounds. - Compression Ratio: Typically around 10:1, balancing quality and size. - Bitrate: Encoded at different rates, affecting quality and size. - Sampling Rates: Supports various rates, including CD quality. - Channel Modes: Offers mono, stereo, joint stereo, and dual channel. - Metadata: Stores info like title, artist, and genre (ID3 tags). - Streaming: Suitable for internet audio streaming. - Universal Playback: Compatible with most devices and software. - Variable Bitrate (VBR): Dynamically adjusts bitrate for efficiency. - Frequency Range: Covers 20 Hz to 20 kHz (human hearing range). - File Size: Much smaller than uncompressed audio. - Psychoacoustic Model: Removes less audible frequencies. - Developed by Fraunhofer Society in the 1990s. MP3 revolutionized the music industry for its efficient compression and wide compatibility, enabling digital audio storage and sharing.
