Feature description:
Please extend the equalizer bands to include subwoofer bands. The extra bands 5, 7, 9, 11, 15 Hz
Problem solved:
Control and shape subwoofer frequencies below 20hz. Although beyond the human hearing range, the lower frequencies are felt and resonate through the body where the brain picks up and decipher to us as sound.
Sound is very personal, so even the best designed inear buds, will not cater to all ears and preferences.
Reshaping frequencies below 20hz will allow better control as compared to a generic curve below 20hz.
Not all drivers are created equal. The extra frequencies will allow either reduction or boost of the higher lower frequencies, so the lower harmonics (warmth) of a musical instrument can be relegated to the subwoofer.
For example, a kick drum has frequencies ranging 200hz to 10hz. Too much of the mid lower frequencies, will be perceived as a bad kick drum because it does not have the “boom”. We can increase from 95hz down to 20hz. But then we will face the issue of "mud"ding the kick sound because it will also increase the frequencies of the bass guitar.
Some of modern hip-hop or bass heavy music have been studio equalized to produce the lower “Boom”. Hence if we are able to reduce some of the kick drum frequency between 20 - 95hz to leave room for the bass guitar to shine and delegate the “Boom” to the subwoofer by increasing the sub-lower frequencies between 5hz to 17hz. This will allow the Boom to Boooomed without mudding the bass guitar.
Brought benefits:
Boost or cut lower frequency for better control to simulate subwoofer for 10mm and higher drivers for inear buds.
This will also help to better control OEM subwoofers in cars while using Android Auto or carplay.
Modern cars with OEM sounds systems are very expensive and difficult to replace unlike generic car sound of pre 2000s.
Other application solutions:
Poweramp
Additional description and context:
I like that Symfonium does not have a default equalizer preset.
Android Auto controls the OS and this is annoying in that it over-rides Poweramp’s saved EQ presets to default.
So everytime I start the car, I have to start Poweramp to play (even if I do not want to listen to music yet), so I can change the EQ from Default to my preset. This is due to this country’s heavily cam’d “No Touch Phone while in car for driver” laws.
Symfonium does not have default settings so Android Auto cannot mess with it.
I also find that Symfonium has a better GUi and more user practical settings.
I would like to use Symfonium but at present I cannot control the sub-lower frequencies and hence, at present, Poweramp provides control over the subwoofer.
