A theoretical ideal for audio components, especially speakers, representing a frequency response that does not deviate from a flat line over the audible frequency spectrum when fed a flat-line test signal. While a flat response is ideal, it is impossible in real world listening due to not only the speaker itself but also its interactions with the room and various surfaces within the room. A speaker can often be moved and adjusted to achieve a flatter frequency response within a given room.
An output signal in which fundamental frequencies and harmonics are in the same proportion as those of the input signal being amplified. A flat frequency response would exhibit relatively equal response to all fixed-point frequencies within a given spectrum.
A componet has a flat response when all frequencies are equally emphasized. Having a flat frequency response is a desirable thing.
Refers to a flat, or linear, frequency response, meaning that an audio component can reproduce all audio frequencies at the same, correct, level. See Frequency Response.
A frequency response that is uniform and equal at all frequencies.
In audio, a condition whereby a signal is not boosted or attenuated at specific frequencies over its operating range.
The faithful reproduction of an audio signal; specifically, the variations in output level of less than 1 dB above or below a median level over the audio spectrum.
Is the capacity of a speaker to reproduce sound without adding any artifacts or distortions to it. Flat response speakers are close to the ideal speakers.
The reproduction of sound without altering the intensity of any part of the frequency range.
The ability of a speaker or amplifier to reproduce all points of the frequency band equally, without dips or peaks when referenced to the original input.
