![]() ![]() Equalizing that massive >10 kHz valley on the V6 would be unwise as it'd likely create audible distortion (and, worse, if a measurement is unrepresentative of your headphones on your head, boosting 10,000 Hz+ content too strongly could be harmful to your ears), so we'll select 20 Hz to 10,000 Hz. Under filter tasks, select the frequency range you wish to equalize. For this measurement the bass at 20 Hz is -6.7 dB, so I'll set it to that. Set target level to whatever the amplitude value is of the lowest point on the graph you wish to boost. Make sure LF Cutoff, LF Rise Slope and HF Fall Slope are set to 0. Click target settings and set speaker type to full range. Click Equalizer at the upper right and set it to generic. How to automatically EQ the frequency response you just loadedĬlick the EQ button at the top of REW. You have successfully loaded the Headroom measurement into Room EQ Wizard:Ģ. csv file to remove any rows which are out of order, as REW expects the frequency values to increase for every new downward row. If, at this point, you get an error, you probably need to manually edit the text of the. csv you just created in LibreOffice Calc/Excel. Open Room EQ Wizard, which can be found at Ĭlick file menu => Import Frequency Response. Go to file menu => Save As and save as a. Delete all columns except "dataSeries_data_value_001" and "dataSeries_data_value_002." Delete row 1. Check comma and only comma under Separator options. Open the file in LibreOffice Calc (Excel should work too but I will not explain how to use it as I don't have it). I've been using and I just open the JSON with Wordpad, copy all the text, paste it into the box, click the big green download button and save the. Use a JSON to CSV converter to convert the JSON file to CSV. Click download and select your location for it. Use the lowest X and Y values you can which can successfully generate a one dot thick line covering the whole measurement. If the result is multiple dots thick, raise the X and Y values under algorithm and click Run again. You want the result to be a single line of dots covering the measurement line. Trace over the measurement line with the pen, making sure you cover all of it. The thinner the stroke you use, the more precise your generated data can be. Adjust the stroke width to the thinnest you're comfortable using. Click the color box next to foreground color. Amplitude will probably not be in a log scale, so leave log scale unchecked for Y-axis. Frequency will probably be in a log scale, so click log scale for X-axis. Click complete after adding the four points. Click proceed and follow the directions just given. Follow its directions, and note the frequency and amplitude values you click on. A diagram will pop up instructing you what to do next. Select 2D (X-Y) Plot and click Align Axes. Go to File => Load Image and load your measurement. ![]()
