Power Switch - Depress to turn the EQ-One on.Ģ. THE EQ-ONE'S CONTROLS AND THEIR FUNCTIONSįront Panel (Fig. This LED display provides you with the information needed to quickly equalize that speaker's response curve to flat, using the Graphic Equalizer section of the EQ-One. The crophone will transmit this response curve to the Real Time Analyzer section of your EQ-One, which will display this curve through a series of LEDs (Light Emitting Di odes). Some frequencies will be emphasized, and others subdued, due to your speakers and the effects of sir surroundings on their frequency response curve. This Pink Noise, as it emanates from the speaker, will no longer contain equal parts of all frequencies. This is played through one speaker at a time, and mon itored by a calibrated condenser microphone with your EQ-One. The EQ-One equalizes by generating a sound called Pink Noise, which is composed of equal parts of all frequencies. The EQ-One allows you to compensate for all these variables, adjusting each channel separately, so that your system's frequency response curve closely approximates the ideal "flat" curvel Other func tions the EQ-One performs will be covered later in this manual. Additionally, very few rooms are shaped and furnished symetrically, so one invariably ends up with each speaker having a different frequency response curve, and thus sounding different, due to the difference in walls and furnishings in its proximity. ing room, and will sound different in every room you might place them in. This is why your speakers probably sounded different when you brought them home than they did in the store's listen. Your listening room, and the furniture in it, act as extensions of your speakers, alter ing the frequency response curve of your entire system. Your EQ-One will perform a variety of functions, but its imary use is to provide you with all you need to compen sate for the sonic Influence of your listening room and its furnishings on the sound of your stereo system, all built into one compact component. WHAT THE EQ-ONE DOES FOR YOUR STEREO SYSTEM You have just purchased a new component for your stereo system which allows you remarkable flexibility in improving the sound of your system! The various controls on your AudioSource EO-One may seem a bit formidable at first glance, but if you take a few minutes to thoroughly read this instruction manual, you will find the unit very easy to operate. I hope that helps get you started (at least on the filtering part.) If you figure out how to write a real-time filter that can directly inject itself in to the Windows sound architecture, let us know.Audiosource eq-one in good working condition tested on home stereo all functions are working properly i know it sure made my system come to life also you can hook up a audio measuring mic to the microphone input jack and run a pink noise test of your speaker set up to get the best possible sound vary nice feature microphone not included is available on line separate Below is s description of how the unit operatesĮQ-ONE REAL-TIME ANALYZER GRAPHIC EQUALIZER AND PINK NOISE GENERATOR Some Google searching also turned up this resource: I would start by seeing what the open source programs do: Audacity is one: you can explore the equalization and audio filter plugins to see if they meet your requirements. So what you need to build is a programmable notch filter, then stack them to get as many bands as you need. A parametric EQ lets you set the specific frequency of each filter, and a good parametric EQ plugin will let you set as many or as few filters as you need. The best eq system is a set parametric eq's. Center your EQ on 1KHz (1000 Hz) and go up and down in factors of 2. In an abstract sense, a graphic equalizer is a set of notch filters, each one tuned to a specific frequency. ![]() I can only offer some insight about the filtering part. You didn't say whether your sticky point is creating the audio filters or injecting your audio in to the system's audio stream. ![]()
