A-B Comparison refers to the process of switching between two audio sources or parts of a gear / equipment to compare a parameter setting, component, or sound quality. The best A-B comparisons are “blind,” where the listener does not know the identity of the sources until after the test is concluded. The test results are better if the two sources can be switched instantly.
More about A-B Comparison
An A-B comparison is a method used to evaluate the performance of two audio sources or pieces of equipment. The process involves switching between the two sources and comparing a specific parameter, component, or sound quality. A-B comparisons are commonly used in the audio industry to evaluate and compare different equipment, such as amplifiers, speakers, and microphones.
Understanding A-B Comparison
A-B comparison is a useful tool for evaluating the performance of audio equipment. It allows for a direct comparison between two sources and can provide valuable information about the relative strengths and weaknesses of each source. The process of A-B comparison is simple, but it is important to understand some key concepts to ensure accurate and meaningful results.
Advantages of A-B Comparison
One of the main advantages of A-B comparison is that it allows for a direct comparison between two sources. This means that the listener can hear the differences between the two sources and make a more informed decision about which source is better suited for their needs. Additionally, A-B comparison can be used to evaluate a specific parameter, such as frequency response, noise floor, or distortion, which can provide valuable information about the performance of the audio equipment.
Blind A-B Comparison
A-B comparison is most effective when done “blindly,” where the listener does not know which source is playing at any given time. This helps to eliminate any potential bias and ensures that the test results are as accurate as possible. This is often referred to as “blind A-B comparison.”
Switching Time
It is important that the two sources can be switched instantly to minimize any effect of switching on the listener’s perception. This allows for a more accurate comparison and ensures that the listener is not influenced by the switching process.
