A common pre-processing tool used to compensate for the average spectral shape is pre-emphasis, which emphasises higher frequencies. Typically, pre-emphasis is applied as a time-domain FIR filter with one free parameter, for example, in speech coding at a sampling rate of 8kHz or 12.8kHz, we use the pre-emphasis filter .

The amount of pre-emphasis in US FM transmission and sound transmission in TV has been standardized at 75 μsec. The pre-emphasis circuit is basically a high pass filter. The pre-emphasis is carried out at the transmitter.The frequency for the RC high pass network is 2122 Hz as shown in fig.1 (b).
Pre-emphasis and De-emphasis - D&E Notes

Pre-emphasis refers to boosting the relative amplitudes of the modulating voltage for higher audio frequencies from 2 to approximately 15 KHz. De-emphasis De-emphasis means attenuating those frequencies by the amount by which they are boosted. However pre-emphasis is done at the transmitter and the de-emphasis is done in the receiver.
FM Pre-Emphasis and De-Emphasis - Radio Museum

FM Pre-Emphasis and De-Emphasis. FM systems use a pre-emphasis for the audio signals. That means, all audio frequencies above a corner frequency are emphasized. The corner frequencies are: f c = 2.1221 kHz for region 2 (the Americas) f c = 3.1831 kHz for Region 1 (Europe and Asia) This gives the time constants: τ = 75 μsec for region 2.
