Adjust the direct monitoring of your measurement microphone. Make sure that you hear the sound of the measurement microphone in one of your speakers when you touch the measurement microphone. Then include the Room EQ VST plug-in to that project and open the plug-in window in accordance with the manual of your VST host software.\u003cbr\u003e- If you use the Foobar2000 version of the plug-in, click File - Preferences - Playback - DSP Manager, then select \"MathAudio Room EQ\" in the right pane and click the right-to-left arrow to activate it.

If you use the VST version of the plug-in, the microphone input device coincides with the input device of your DAW and you can change it in your DAW settings if necessary. If you use the Foobar2000 version of the plug-in, you can change your microphone input device by means of the additional \"In\/Out\" button which is shown below.\u003cbr\u003e\u003cimg src=\"http:\/\/mathaudio.com\/images\/inoutbutton.png\" alt=\"In\/Out button\" width=\"192\" height=\"96\"\u003e \u003cbr\u003e\u003cem\u003eFig.3.

Please note that the Room EQ plug-in interrupts the signal path in the measurement mode, so you cannot hear the sound of the microphone in your speakers when the measurement mode is activated.\u003c\/p\u003e\n\u003cp\u003eConventional measurement microphones work perfectly with MathAudio Room EQ without calibration. However, if you have a calibrated measurement microphone, you can use it too.

Measure the frequency response of your room and your speakers\u003c\/strong\u003e\u003cbr\u003e- Plan to make no less than 5-20 measurements. The measurement locations must be uniformly distributed within the area of possible locations of all listeners.\u003cbr\u003e- Place the microphone at your ear height. Set it vertically. The microphone should not be near reflective objects or sound absorbing upholstery. It is very convenient to use a tripod.\u003cbr\u003e- Click the \"Start Measurement\" button.\u003cbr\u003e- Wait until the end of the measurement (about 10 seconds). Then move the microphone to the next measurement location and click the \"Yes\" button in the prompt window. Repeat this procedure in all the necessary measurement locations. Click the \"No\" button in the prompt window when you will finish the last planned measurement. You will get the plots of frequency responses as it is shown in Fig.4 (your plots will be different).\u003cbr\u003e- Click the \"Save preset\" button to save the frequency response of your speakers as a \u003cstrong\u003e.snr\u003c\/strong\u003e file.\u003cbr\u003e\u003cimg src=\"http:\/\/mathaudio.com\/images\/room-correction-2.png\" alt=\"screenshot\" width=\"730\" height=\"636\"\u003e\u003cbr\u003e\u003cem\u003eFig.4.

After that click the \"Room EQ\" radio button to activate the Room EQ mode.\u003cbr\u003e- If you use the Foobar2000 version of the plug-in, just click the \"Room EQ\" radio button. If you use other audio effect plug-ins, make sure that Room EQ is included as the last audio effect in the chain.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e8. Balance your speakers\u003c\/strong\u003e\u003cbr\u003eSometimes speakers are not well balanced (i.e. one of them is louder than another). If your speakers are not well balanced you can click the \"Stereo Balance ON\" radio button to compensate for the disbalance. You can skip this step if the frequency responses of the left and right channels of your speakers look similar.\u003cbr\u003eComparison of the left and right frequency responses in Fig.4 shows that the loudness of the right speaker is approximately equal to the loudness of the left speaker and we don't need balancing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e9. Choose the reference frequency response\u003c\/strong\u003e\u003cbr\u003eClick the \"Bright\" button to get a standard flat frequency response of ideal speakers or click the \"Neutral\" button if you want to get the frequency response of ideal speakers with a h.f. roll-off. The latter reference response will ensure more neutral sound of your speakers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e10. Move down the vertical slider\u003c\/strong\u003e\u003cbr\u003eMove down the vertical slider and release it to cut out some part of the main resonances as it is shown in Fig.5.\u003cbr\u003e\u003cimg src=\"http:\/\/mathaudio.com\/images\/room-correction-3.png\" alt=\"screenshot\" width=\"730\" height=\"636\"\u003e\u003cbr\u003e\u003cem\u003eFig.5. Cutting out a part of the main resonances of the room and speakers.\u003c\/em\u003e \u003cbr\u003e\u003cbr\u003eThe resultant processed frequency response of your room and speakers will be shown by a white line as it is shown in Fig.5. It is possible to see that the main resonances of the resultant frequency response (white line) became much smaller. Such resonances added unnatural timbre to the sound. The removal of the resonances dramatically improves the sound.\u003cbr\u003eIt is also possible to see that MathAudio Room EQ doesn't boost the spectral components lying below the green line. This important feature prevents the large excursions of the speaker diaphragm that can be caused by the ideal linearization of the frequency response. Besides that this feature allows you to avoid the overcompensation of your room. As a result you will not get a muddy sound that is peculiar to conventional linearizing equalizers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e11. Compare processed sound of your speakers with their original sound\u003c\/strong\u003e\u003cbr\u003eMake sure that the \"Room EQ\" radio button is selected as it is shown in Fig.6 (a). Play music. Remember the loudness of the processed sound of your speakers. Then click the \"Bypass\" radio button to listen to the original (unprocessed) sound and move the \"Bypass signal volume\" slider left until the loudness of the original sound becomes equal to the loudness of the processed sound: equal loudness is necessary for correct comparison of the processed and original (unprocessed) sounds. Switch \"Room EQ\" and \"Bypass\" radio buttons and adjust the position of the volume slider until the loudness of the processed sound will be equal to the loudness of the original (unprocessed) sound (see Fig.6 (b) and (c)). Compare the qualities of the processed and original (unprocessed) sounds.\u003cbr\u003e\u003cimg src=\"http:\/\/mathaudio.com\/images\/s2.png\" alt=\"screenshot\" width=\"680\" height=\"162\"\u003e \u003cbr\u003e\u003cem\u003eFig.6.

Change the position of the vertical slider and repeat the test\u003c\/strong\u003e\u003cbr\u003eYou need to make at least a few experiments to find the optimum location of the vertical slider. The optimum location of the vertical slider corresponds to the maximum fidelity and transparency of the sound. Your ears have the final say.\u003cbr\u003eMove the vertical slider up and down a little and compare original and processed sounds. Don't forget to adjust the loudness of the original sound for correct comparison of the processed and original sounds. Different positions of the vertical slider result in different shapes of the frequency response (compare Fig.5 and Fig.7).\u003cbr\u003e\u003cimg src=\"http:\/\/mathaudio.com\/images\/mathaudio-room-eq-vst.png\" alt=\"screenshot\" width=\"730\" height=\"636\"\u003e\u003cbr\u003e\u003cem\u003eFig.7.

If the volume of the processed sound is still not sufficient, choose a higher position of the vertical slider.\u003cbr\u003eIf unpleasant rattling is present at low frequencies, you also need to choose a higher position of the vertical slider.\u003cbr\u003eRepeat the audio test for different positions of the vertical slider and choose the best one. Leave the best position for the permanent use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e13. Draw and try your own reference frequency response if you still wish to change something in the sound\u003c\/strong\u003e\u003cbr\u003eThis step is optional and can be recommended for those who want to fine-tune the timbre of the sound. For example, you can modify the built-in reference frequency responses and listen to the result. MathAudio Room EQ contains a convenient tool for drawing your own reference frequency response.
