Hangkódolási

Hangkódolási refers to the process of converting audio signals into a digital format. This is a fundamental step in many digital audio technologies, including digital audio recording, streaming, and compression. The core idea is to represent the continuous waveform of sound as a sequence of discrete numerical values. This is typically achieved through sampling and quantization.

Sampling involves taking measurements of the audio signal's amplitude at regular intervals. The frequency at which these measurements are taken is called the sampling rate. A higher sampling rate generally results in a more accurate representation of the original sound. Quantization then assigns a numerical value to each sampled amplitude. The precision of this assignment is determined by the bit depth, which dictates the number of possible values that can represent each sample. A higher bit depth allows for a finer gradations of amplitude, reducing distortion.

Various algorithms and techniques exist for hangkódolási, each with different trade-offs between fidelity, data rate, and computational complexity. These methods are crucial for enabling the storage, transmission, and playback of digital audio. Understanding hangkódolási is essential for comprehending how digital sound is processed and manipulated in modern electronics and communication systems.
