High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth.It commonly refers to 96 or 192 kHz sample rates.
The dynamic range of an audio system is a measure of the difference between the smallest and largest amplitude values that can be represented in a medium. Digital and analog differ in both the methods of transfer and storage, as well as the behavior exhibited by the systems due to these methods.
An audio analyzer is a test and measurement instrument used to objectively quantify the audio performance of electronic and electro-acoustical devices. Audio quality metrics cover a wide variety of parameters, including level, gain, noise, harmonic and intermodulation distortion, frequency response, relative phase of signals, interchannel crosstalk, and more.
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 ...
Considerably more music (with respect to total running time and quantity of songs) or; Encoding at higher linear sampling rates and more bits-per-sample, and/or; Additional channels for surround sound reproduction. Audio on a DVD-Audio disc can be stored in many different bit depth/sampling rate/channel combinations:
It is difficult, but very important, to match sound levels before comparing systems, as minute increases in loudness—more than 0.15 dB [11] or 0.1 dB [12] —have been demonstrated to cause perceived improvements in sound quality. Listening tests are subjected to many variables, and results are notoriously unreliable.
A test CD is a compact disc containing tracks of musical and technical tests and demonstrations. Most of the tracks are made of electronic signals and pure frequencies . The purpose of these specialized compact discs is to make accurate tests and calibrate audio equipment .
It is a formidable challenge for an amplifier, subwoofer speakers, and cabinet to reproduce these sound effects at a high volume without encountering problems such as power amplifier clipping (distortion), unwanted rattle or resonance in the wooden cabinet, or excessive "chuffing" sounds from the bass reflex vent (if a vent or port is used in ...
