While this can sound more than a little cheeky and with a hint of possible false advertising, the benefits are clear. In one instance, calibration can further increase the accuracy of studio monitors by better tuning them around the listening environment.Īnother use of calibration works around the electrical bias in lower cost and less accurate speakers to improve the frequency response, using DSP to flatten the shaped curve. Digital calibration debuted on studio monitor speakers before crossing over to home theater systems.Īdjustable calibration is particularly interesting because of its possible applications. The idea behind it is to allow sound systems to adjust their output frequency response to compensate for the room’s frequency response. One area that has gained significant traction outside pro audio circles in the last decade is automatic speaker calibration. Home theatre systems opt for a more portable interface in the form of a custom or USB connector for their calibration microphones. It’s used for measuring and calibrating rooms and can pair with Behringer’s DEQ2496 EQ analyzer processor. The Behringer ECM8000 is an affordable calibration microphone with an XLR interface. Their primary use is for vocal auditions and room calibration, respectively. Model types include reference vocal microphones and calibration microphones. Microphones with a flat response also exist but make up a smaller portion of models overall. Flat frequency curves are not naturally occurring and are purely artificial. The cost factor comes down to electrical components, bias and tolerance. So much so that most people prefer a shaped curve for day-to-day listening because flat response curves can sound boring or lacking drama to casual listeners.Īchieving a flat response comes with one drawback: cost. Nonflat response speakers are most commonly used in consumer systems because they can get away with less accuracy. Just like their visual counterparts, a good pair of studio speakers deserve to go into a suitable room. Flat frequency response in speakers is necessary for the accurate reproduction of sound. Let’s refer back to the color gamut and accuracy analogy. These factors are primarily down to product and consumer category, which directly determine the cost and the device’s intended use. Shaped response curves are common across most speakers and microphones for several reasons. The cardioid pattern focuses the pickup pattern towards the front and makes it a great fit for broadcasts by rejecting most of the sound around it. That’s not to say it is a slouch at regular volumes. Its dynamic side makes it capable of taking a beating, and vocalists can really project into it without fear of distortion. The SM7B is a dynamic cardioid microphone. This is a big part of why microphones have different timbral qualities - also explaining their ability to add texture and color to a recording.įor example, take the Shure SM7B and its reputation for delivering rich, smooth vocal recordings. The answers to which should make the user experience more meaningful.Ī microphone’s exact shaped response is the byproduct of its design and electrical component selection. What does a shaped frequency response sound like, and how does it impact my work? Both of these are great questions. While not a distinct curve design, the technology has matured over the last fifty years and is worth considering. Adjustable curves that use digital signal processing (DSP) have been crossing over into consumer theatre systems for some time now. Both curve types feature in microphone and speaker designs. shaped frequency responseĪudio frequency response curves come in two distinct types, flat and shaped. There are also several types of digital and analog signal types available for use. The reference signal must use constant amplitude. A reference signal is sent through the device input that sweeps through the frequency spectrum. If you happened to read our guide on acoustics, you’re already familiar with the measurement methodology.
