Audio bit depth. An analog signal (in red) encoded to 4-bit PCM digital samples (in blue); the bit depth is four, so each sample's amplitude is one of 16 possible values. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample.
User-generated database of comparison between original tracks and covers, or songs that use samples. 460,000. 150,000. SIMUC. Chilean music and musicians. SIMUC is a Non-profit organisation that collects data on composers, academics, institutions, people and other topics related to classical music and Chile .
Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to ...
This is the ratio (usually expressed in dB) between the noise floor of the device with no signal and the maximum signal (usually a sine wave) that can be output at a specified (low) distortion level. Since the early 1990s it has been recommended by several authorities including the Audio Engineering Society that measurements of dynamic range be ...
t. e. An audio frequency or audible frequency ( AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [ 1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz. [ 2][ 3][ 4] In air at atmospheric ...
dBFS. Clipping of a digital waveform. The red lines indicate full scale, and the waveform is shown before and after hard clipping (grey and black outlines respectively). Decibels relative to full scale ( dBFS or dB FS) is a unit of measurement for amplitude levels in digital systems, such as pulse-code modulation (PCM), which have a defined ...
A Dolby noise-reduction system, or Dolby NR, is one of a series of noise reduction systems developed by Dolby Laboratories for use in analog audio tape recording. The first was Dolby A, a professional broadband noise reduction system for recording studios in 1965, but the best-known is Dolby B (introduced in 1968), a sliding band system for the consumer market, which helped make high fidelity ...
EBU R 128. EBU R 128 is a recommendation for loudness normalisation and maximum level of audio signals. It is primarily followed during audio mixing of television and radio programmes and adopted by broadcasters to measure and control programme loudness. [1] It was first issued by the European Broadcasting Union in August 2010 and most recently ...
