Understanding Audio Jargon

  • Digital-to-Analog Conversion: DACs are electronic devices that convert digital signals into analog signals. This process allows the reproduction of digital audio files as sound waves that can be heard through speakers or headphones
  • Sampling Rate: The sampling rate refers to the number of digital samples taken per second to represent an analog signal. It is usually measured in Hertz (Hz) or kilohertz (kHz). A higher sampling rate results in more accurate representation of the original analog signal and better audio quality
  • Bit Depth: Bit depth determines the number of bits used to represent each sample in a digital audio signal. It directly affects the dynamic range and resolution of the audio. Higher bit depths allow for more accurate representation of subtle sound variations, resulting in improved audio quality
  • Signal-to-Noise Ratio (SNR): SNR is a measure of the amount of unwanted noise present in an audio signal compared to the desired signal. It is usually expressed in decibels (dB). A higher SNR indicates a cleaner and more accurate audio reproduction
  • Line-Level Output: Line-level output is a standardized signal level used to connect audio devices together. DACs typically provide line-level outputs that can be connected to amplifiers, preamps, or other audio equipment
  • Upsampling: Upsampling is a process in which a lower resolution digital audio signal is converted to a higher resolution before being converted to analog. This technique is used in some DACs to improve the audio quality by reducing the quantization noise and distortion
