An inconsistent headphone may have a drastically different sound from listener to listener. Although most listeners naturally compensate for variations in frequency response caused by their unique features, such as the shape and size of their heads, other factors like their preferred headphone position, and how the ear cups' acoustics interact with their ears, may cause additional variations in the response.
Headphones will sound slightly different depending on the size and shape of your head, how they interact with your ears and whether you wear glasses.įrequency response is the most important part of good audio reproduction.

Audio is also sometimes recorded at 88.2kHz or 96kHz in a process known as oversampling, wherein the sample rate is taken to be well over the Nyquist frequency in order to improve resolution and signal-to-noise ratio. Humans can hear sounds in the 20-20,000 Hz range, so music and other sound waves are often sampled at 44.1kHz or 48kHz (slightly over the Nyquist frequency). How does sample rate affect sound quality?Īudio signals are subject to the same criteria as other analog signals. Higher sample rates typically come at the cost of slower speeds and higher power consumption.
The Nyquist criterion sets a theoretical lower limit, and in practice, sample rates must be (sometimes much) greater than twice the highest frequency to be sampled for the signal to be accurately converted. The Nyquist frequency is equal to half of the sample rate, so increasing sample rate means that higher frequencies can be recorded without aliasing.

Is a higher sample rate better?įor a sampled signal to be free of distortion known as aliasing, the Nyquist frequency of the sampler must be greater than the highest frequency that needs to be preserved. Sample rate and sampling frequency represent the same value. Hertz is the unit for frequency, and the sample rate is sometimes referred to as the sampling frequency. The two are equivalent since the Hertz is equal to the reciprocal second, =. The units for sample rate are samples per second (sps) or Hertz (Hz). The sample rate (or sampling rate) is the number of samples taken per second. An ADC takes a continuous analog signal and converts it to a discrete digital signal by taking samples that represent the signal’s amplitude at specific points in time.
