Flat Frequency "Loudness" @ Any Volume Level

[shkumar4963]

Does anyone know a way to introduce a frequency equalizer in the line that changes the equalization curve based on volume.

We all know that we perceive low frequency much less at lower volumes than at high volumes. In 80s, there used to be a bass boost switch that tried to correct for that. But it was a one step boost and not that accurate. Now with digital equalization technology it should be possible to get a flat frequency "perception" or "loudness"
curve at any volume level.

I am hopeful that this is available from some manufacturer. But if it is not, would love to hear why you feel it is not needed.

Audyssey Dynamic EQ.

Usually the ReplayGain setting in software players. I think Foobar has one.

ReplayGain - Hydrogenaudio Knowledgebase

Replay gain just increases the volume of the tracks / album.

You're right. I misunderstood the question. I thought OP was talking about dynamically adjusting loudness.

It is called 'active equalization'.

The most used method in stereo systems is the passive ones and does not change the equalization in real-time mode based on the volume. Those systems do equalization based on the position of volume control, and not based on the signal strength which could be different on loud passages in a song and soft passages.

I personally like the active equalization concept in Bose music systems.

That sounds like Dynamic Volume, which is also not the same. It changes the volume of the content, not the frequency curve. Dynamic EQ compensates for the reduced perceived low frequency at lower volumes. What he want's is based on the position of the volume control.

May I ask why you need it?
If it is for loosing bass at low volume, then that actually can happen for many reasons, poor designed speaker, amplifier, intentional recording are being few.

What I do in such cases is change equalization in amp or in my graphic equalizer or in foobar depending on my source.

Let me know, if I missed something in understanding your request actually.

Sumanta. let me explain. A producer adjusts intensity of different tracks to sound about right to him. He does it at a volume often referred to as reference volume. When I hear the same recording at much lower volume I don't hear the lower frequency at the same RELATIVE level as he heard when he was producing the music. Also his frequency vs. Perception curve was different than mine and that has to be compensated for as well so that my perceived RELATIVE volume of different frequencies arw same as his. I was referring to the first pary. The second is much harder.

Also, since I listen to music sometime loud and sometime soft, I need to correct the equalization at each volume so that my relative perception of low and high frequencies remain the same.

Hope this helps.

There is a loudless button on most older 2 channel amps for use

at lower listening levels, when you raise the volume release the

loudness button this is the most simple way, active Eq requires a mike placed

near the listner, and it can be off depending on the type of music playing it can be
good but its complicated
