Bass Frequency Cutoff

Post by estalson1 »

Some recordings have bass content below the capabilities of a user's speakers/subwoofer. This results in a low bass noise since the speakers cannot reproduce the detail in the lowest end or the recording. For example, I have an inexpensive subwoofer that doesn't resolve sounds below 40 Hz and it does not have a cutoff filter. I h have tried using the equalizer (set to -20 dB in the 31 Hz and 63 Hz bands and it does eliminate the unresolved bass content. However, I feel I am losing useful bass content as well. The ability to set a precise bass cutoff would be helpful. Different cutoff values would likely be necessary to allow for variations speaker brands/models.

You can make any audio curve you wish by using open-source Peace.
A bass cut-off (high-pass) filter is easily done and can be graphically adjusted in real-time.

"Peace equalizer is a Windows PC interface for Equalizer APO http://sourceforge.net/projects/equalizerapo. Besides an system-wide audio equalizer on your Windows PC, Peace has an effects panel for balance, crossfeeding, delay, etc., a graph window and much more."

https://sourceforge.net/projects/peace- ... extension/

IMO it is the best headphone equalizer program there is. You can find many calibration EQ curves for each of hundreds of headphones and ear buds. Enjoy!

Hi,
Hmmm, Josh, that is a nice EQ. THX will check it out for sure.

Amplifying on my post: 'Equalizer APO' should be installed first:

"Equalizer APO is a parametric / graphic equalizer for Windows. It is implemented
as an Audio Processing Object (APO) for the system effect infrastructure
introduced with Windows Vista."
https://sourceforge.net/projects/equalizerapo/

Peace is the GUI front-end to Equalizer APO.

I experimented in Peace to make a bass cut filter.
I selected the "Equalizer 5-Band" preset, then modified the filter and frequency of the first slider band.
Set Frequency to 40 Hz.
Right-click on the first band's filter and choose "High Pass Butterworth Filter (even orders only)".
This gives a sharp cut-off, as can be seen by displaying the Graph Window.
The standard "High Pass" filter has a sharp peak before the cut-off.
You can set the Graph Window to allow dragging of the handles.

Thank you! I have installed PEACE and am very pleased with it. Are there other apps, outside the Media Monkey environment, that can improve on performance of my audio system like this?

Thanks again! I love how quick and easy it was to solve my problem with junk bass noise.

There probably are other useful audio control programs for Windows, but I do know of any myself.
But, in Android, if you want to use the same headphone calibration profiles that Peace can use, try the Wavelet app:

https://play.google.com/store/apps/deta ... r&hl=en_US

The Android app Poweramp is the ultimate multi-band adjustable EQ with from 5 to 32 bands, and can be switched to Parametric mode. Also has a Limiter and bass and treble controls.

Poweramp's Parametric mode filters can be adjusted for level, Q and frequency. Does not have the additional HighPass etc. filter types that Peace does. But if you wish play music on your phone wirelessly (Wifi or BT) to your sound system, you can create a Parametric filter at, say 35 to 40 Hz with high Q to cut off/reduce the very low bass.

Both Wavelet and Poweramp can be used together.

Hi,

To address the issue of unresolved low bass content, consider using a high-pass filter with a cutoff frequency just above your subwoofer’s limit, typically around 40 Hz. This approach will help remove the problematic low bass content without significantly affecting the useful bass. Many audio processors and digital equalizers offer adjustable high-pass filters, which can be set to match your specific speaker’s capabilities and avoid unnecessary loss of valuable bass information.

That sounds like a solid solution. Perhaps it’s worth experimenting with different filter slopes or Q settings to see if that gives you even more control over how the low end is cut off, while still keeping the useful bass intact.

Hi Josh! Hope you are doing well. Can you please tell me more about this IMO Headphone Equalizer program? I listen to songs almost 9-10 hours a day and prefer bass-boosted music. I would love to listen to them all day. So that's the main reason to know about this program.
Thank you,
Mike Taku.
