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 ...
Block diagram of the signal-flow for a common feedback loop. [1]: 118 Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio output (for example, a loudspeaker) and its audio input (for example, a microphone or guitar pickup).
The term 1-dimension refers to a simple pistonic relationship between the noise and the active speaker (mechanical noise reduction) or between the active speaker and the listener (headphones). Protection of a 3-dimensional zone requires many microphones and speakers, making it more expensive.
Russell O. Hamm, an engineer working for Walter Sear at Sear Sound Studios, wrote in 1973 that there is a major difference between the harmonic distortion components of a signal with greater than 10% distortion that had been amplified with three methods: tubes, transistors, or operational amplifiers.
In signal processing, distortion is the alteration of the original shape (or other characteristic) of a signal.In communications and electronics it means the alteration of the waveform of an information-bearing signal, such as an audio signal representing sound or a video signal representing images, in an electronic device or communication channel.
This allows headphones of a low sensitivity to be driven louder as a result of the extra voltage provided by the amplifier. There are potential fidelity gains if headphones are driven with lower distortion than using a headphone amplifier integrated into a general purpose audio product.
Right now, Lalgee said, many companies are struggling to gain loyalty from employees. In the recruitment universe, he said, he hears comments all the time about how many younger people don’t ...
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. [1] The first was Dolby A, a professional broadband noise reduction system for recording studios that was first demonstrated in 1965, but the best-known is Dolby B (introduced in 1968), a sliding band system for the consumer market ...
