List of Amir's Headphone GEQ filters

See the SPOILER for a quick and dirty script to convert the files @sweetchaos had mentioned. Save the contents to wavelet_conv.py. You can try executing directly (./wavelet_conv.py input_file.txt) or you can call from python (python3 wavelet_conv.py input_file.txt, if you're getting errors). Please read the notes at the beginning of the file for how to use it or what it does.

Please let me know if you want additional features or changes to formatting.

Thanks for creating this script @GWolfman
This is very helpful.
This will save me from making data-entry mistakes and speed up the process.
Appreciate it. :D

Hmm, I'm still on the borderline for this...

Here's what I wrote earlier (in another thread):
How to upgrade Foobar2000's (for Windows) 18-band GEQ (with +-1dB gain adjustments), to a 31-band GEQ (with +-0.1db gain adjustments)?
1. Get the free addon "Graphic Equalizer" from https://www.foobar2000.org/components/view/foo_dsp_xgeq
2. Download, save .zip to desktop
3. Foobar2000, file, preferences, components, select "install" button, select .zip from desktop, "apply", it will restart Foobar
4. To adjust GEQ, go to View, 'Graphic Equalizer', you'll see the 31-band GEQ (with +-0.1db gain adjustments).
Note: The original GEQ is still there, just under View, DSP, Equalizer.
Click to expand...

Which quickly converts the 18-band GEQ (with less accurate gain adjustments) to the 31-band GEQ (with more accurate gain adjustments), almost instantly....and for free.

To get even better results:
For Windows, you can use 'Equalizer APO' or 'Peace' (both free) to get the more accurate PEQ.
For iOS/iPadOS, you can use 'Neutron Music Player' (paid) to get the more accurate PEQ.

I forgot about that EQ, as a matter in fact I might already have it installed. Stick with the 31-band. Thanks for the reminder.

I need someone else with an Android (I can't, since I have an iPhone), to install 'Wavelet' (free app), and try to import any of my 127-band GEQs.

I'm not sure if the issue is because I tried doing this all on my phone or not (including creating the text file in Google Docs and exporting to a .txt file), but the attached file did not import. (I think this is the Sony MDR-ZX110.)

@sweetchaos I've got some other ideas to automate some of the steps so it's less manually intensive. Let me know if you're interested.

I would try a straight upload of a text file to your phone. I did the same thing you did, and the one from Google Docs (exported to txt) wouldn't import at all, but one from my computer would import (and just not do anything).

I'll try later today. If it works, I'll compare the two and try to find out what's different.

This doesn't import:
$ file HifimanHE400i-AmirM.txt
HifimanHE400i-AmirM.txt: UTF-8 Unicode (with BOM) text, with very long lines

This imports:
$ file HifimanHE400i2016-GEQ-AmirM.txt
HifimanHE400i2016-GEQ-AmirM.txt: ASCII text, with very long lines

I can confirm that your profile works when ASCII-formatted (possibly even UTF-8), but not when the BOM (byte order mark) is included (e.g., when creating and exporting from Google Docs).
 
Added Improvements:

For anyone using VLC media player:
By default, VLC comes with a 10-band GEQ profile, with frequencies 60,170,310,600,1000,3000,6000,12000,14000,16000
But this is non-standard and won't match with the typical ISO standard with frequencies 32,64,125,250,500,1000,2000,4000,8000,16000.
To fix this, go to:
1. Preferences
2. Show "All" settings (on the bottom left)
3. Select "Audio" Tab, then "Filters" sub-tab, then "Equalizer" Tab
4. Disable the option "Use VLC frequency bands".
1612903084877.png
Now you can use the typical 10-band GEQ with frequencies 32,64,125,250,500,1000,2000,4000,8000,16000

Hi,

I was able to load the Sony WH-1000XM4 127 band GEQ into the Wavelet App. One funny thing is that when you import a file, it is merely added to the database. Then you must search for and choose it before it can be selected. I was confused at first because I assumed that importing the file would automatically select it. Nope, it is a 2 step process.

Here is the process that I used:

1. Copy/Pasted the line into a text file (UTF-8, LF, no BOM)
2. Saved the file as Sony WH-1000XM4(Amir).txt
2. Downloaded the file onto my Google Pixel 5, Download folder
3. Imported the file, nothing obvious will happen
4. Search for XM4, selected the Sony WH-1000XM4(Amir)

Attached below are screenshots of the GEQ loaded from here, also for academic interest, I attached a screenshot of the built-in AutoEQ for the XM4.
