And now let's turn the low-frequency gain first back down to 0. And now we're back to flat equalization.
Use flat equalization and keep the volume the same the whole time you do the mix to ensure a consistent volume no matter how many tracks are being mixed.

"Flat plus flat equals flat," Steinhardt says.
This assumption is valid for OFDM-OQAM systems since by design the filters should divide the whole bandwidth in subchannels where the radio channel frequency response can be considered approximately flat (since otherwise computationally cumbersome equalization methods would be required).
The success of OFDM systems relies on the orthogonality property of its chosen subcarriers which transforms the frequency selective channel into a set of frequency flat fading channels simplifying the equalization task.
We first equalize the channel contained in matrix by a subcarrier-wise equalization of the flat-fading SDMA channel and thereby spatially separate the single user signals.
Multicarrier schemes such as orthogonal frequency division multiplexing (OFDM) transform a frequency selective fading channel into a flat fading channel, simplifying or even eliminating equalization.
Equalization is often unable to achieve flat frequency response at all listening locations in part because of the resonance (i.e., standing wave) patterns at low frequencies in nearly all rooms.
In particular, we compare the rate based on a widely used transmission structure in both systems, where equal power allocation (meaning a flat power spectral density mask) is used for the transmitted signal of each user, and linear frequency domain equalization is employed at the receiver.
Moreover, if the channel remains constant within one OFDM symbol duration, OFDM renders a convolution channel into parallel flat channels, which enables simple one-tap frequency-domain equalization.
Using MC communications, a frequency selective channel can be divided into several parallel subchannels with flat or mildly selective fading, facilitating channel estimation and equalization (the terms "subchannel", "subband" and "subcarrier" are used interchangeably throughout the whole text, referring to the frequency subband centered at the subcarrier frequency).

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
