Early digital audio gear and video games used 8-bit integer samples or less. Roland's classic TR-909 drum machine used 6-bit integer samples. The number of bits used in each sample directly affects the signal-to-noise ratio and dynamic range of the digital signal, specifically by determining the amplitude of a kind of noise called quantization ...
The time alignment of an amplified music signal and its distortion components has a profound effect on perceived sound quality. Nakamichi researchers discovered that the human ear is much more tolerant of harmonic distortion if the distortion components are time-aligned with respect to the primary signal.
Many electric guitar players intentionally overdrive their amplifiers (or insert a "fuzz box") to cause clipping in order to get a desired sound (see guitar distortion).. Some audiophiles believe that the clipping behavior of vacuum tubes with little or no negative feedback is superior to that of transistors, in that vacuum tubes clip more gradually than transistors (i.e. soft clipping, and ...
When a stereophonic recording is heard through loudspeaker systems (rather than headphones), each ear, of course, hears sound from both speakers. The audio engineer may, and often does, use more than two microphones (sometimes many more) and may mix them down to two tracks in ways that exaggerate the separation of the instruments, in order to ...
Component speakers: These speakers are designed for higher-end car audio systems and typically consist of separate woofers, tweeters, and crossovers. This allows for more precise sound tuning and a higher level of sound quality. Subwoofers: These speakers are designed to reproduce low-frequency sounds, particularly bass.
One of the great viral hits of the moment is DJ Crazy Times and Ms. Biljana Electronica's “Planet of the Bass,” a parody song pulled straight from the absurdity of late ‘90s, early ’00s ...
Many audio components are tested for performance using objective and quantifiable measurements, e.g., THD, dynamic range and frequency response. Some take the view that objective measurements are useful and often relate well to subjective performance, i.e., the sound quality as experienced by the listener. [12]
Modern home cinema systems typically augment the audio output from a DVD player or Blu-ray player with a multi-channel power amplifier and anywhere from two speakers and a stereo power amp (for stereo sound) to a 5.1 channel amplifier and five or more surround sound speaker cabinets (with a surround sound system).
