hangfájl

A hangfájl, often translated as "sound file" or "audio file," is a digital representation of sound. It stores audio data in a format that can be played back by electronic devices. These files are created by capturing sound waves using a microphone and then converting them into a series of binary numbers. Various encoding methods are used to compress this data, reducing file size while attempting to maintain audio quality.

Common hangfájl formats include MP3, WAV, AAC, and OGG. MP3 is widely popular due to its efficient compression, making it suitable for music storage and streaming. WAV files typically offer uncompressed audio, resulting in higher quality but larger file sizes, often used for professional audio editing. AAC is another compressed format, known for its good balance between quality and size, and is frequently used by Apple devices. OGG Vorbis is an open-source alternative offering good compression and quality.

Hangfájlok are used in a multitude of applications, from music playback and podcasting to voice recordings and sound effects in video games and films. They are essential for digital audio distribution and multimedia content creation. The process of creating a hangfájl involves sampling the analog sound wave at regular intervals and assigning a numerical value to each sample, which is then stored according to the chosen file format's specifications.
