digitaaliääni

Digitaaliääni refers to sound that has been converted into a digital format. This means that continuous analog sound waves are sampled at regular intervals and represented by a series of binary numbers. This process allows sound to be stored, processed, and transmitted using computers and other digital devices.

The key to digital audio is the sampling rate and bit depth. The sampling rate determines how many times per second the sound wave is measured, with higher rates capturing more detail. Bit depth refers to the number of bits used to represent each sample, affecting the dynamic range and accuracy of the digital representation. Common sampling rates include 44.1 kHz (used in CDs) and 48 kHz (used in professional audio and video), while bit depths range from 16 bits to 24 bits or higher.

Once sound is digitized, it can be manipulated in various ways without degradation of quality, unlike analog audio which can be affected by noise and distortion. Digital audio editing allows for precise control over volume, equalization, and the addition of effects. It is also the foundation for digital audio formats like MP3, AAC, and FLAC, which compress audio data to reduce file sizes for easier storage and transmission. The widespread adoption of digital audio has revolutionized music production, distribution, and consumption.
