![]() With both my Topping 元0 (sent back to Amazon due to the ESD/blown headphone matter) and the JDS Lab Atom that replaced the 元0 needed to be set to the high gain level for maximum flexibility in listening levels. Of course, the downside of this is that, depending on the EQ applied, a significantly reduced signal level will be sent to a headphone amp. The practical result is that any boost EQ applied in MathAudio Headphone EQ should never clip the output form Foobar. Run a measurement sweep What's next Here are the key differences between the UMIK-1 (original and v2) and UMIK-2: Note: this app note describes use of REW for a stereo system. The filtered output maximum peak is -6 dB below the pink noise output when no filters were applied. It is implemented as an Audio Processing Object (APO) for the system effect infrastructure introduced with Windows Vista. In the second graph, the Headphone EQ slider was set to -6 dB. 241 Reviews Downloads: 68,484 This Week Last Update: Download Summary Files Reviews Support Downloads Documentation Wiki Code Tickets Discussion Equalizer APO is a parametric / graphic equalizer for Windows. The Headphone EQ gains slider was set to 0 dB in this test. The remainder of the filtered response is below the output from Foobar with no EQ applied. The maximum boost peak touches the no EQ applied pink noise output. In one graph, the output of the pink noise signal with no EQ applied in the MathAudio plug in is compared to the output with the HD280 Pro filter active. In this EQ, there is a total range of about 11 dB between the maximum boost and cuts in the filter. If your DAW uses audio outputs that bypass Equalizer APO, all you need to do is use a Convolution VST last in the chain of your stereo bus that will load the same stereo impulse file as Equalizer APO (bypass using your studio monitor convolution for headphone listening, they'll need their own. There is a screenshot shown of an EQ I developed for my Sennheiser HD280 Pro headphones. Output from my laptop went to the ASIO driver for a Topping D10 DAC, and the analog output was input into a Focusrite Scarlett 2i2 with measurements taken with ARTA. 28th June 2019 1 drsoundsmith Gear Head 5 years Equalizer APO for room correction I can't find anything about people talking about using something like Equalizer APO in conjunction with Room EQ Wizard to correct the frequency response of a room for mixing. These were generated by playing a pink noise signal in Foobar 2000 with the MathAudio Headphone EQ plug in enabled in the DSP manager of the Playback Preference. Since then I have made some measurements with the results shown in the attached files. I also said that I had not made any measurements to confirm this hypothesis. In my earlier post on this thread ( #5), I mentioned that it appears that MathAudio Headphone EQ for Foobar reduces the overall output by setting the maximum boost applied in the EQ to a level of 0 dB. ![]() Adjust your preamp filter down until there's no clipping. There will probably be clipping, so you'll have to click the plus sign>Basic filters>Preamp. Give it your WAV file that you just made. This is a follow up to my earlier post on this thread. Click a plus sign>Advanced Filters>Convolution.
