Has anyone attempted to create a better equalizer profile for the embedded microphone?

Yours is my favorite of all the presets!
Makes the speakers less midrange-heavy while giving them all the great bass that they were missing.
Many thanks!!
Edit: I’m using it on the Framework 16

Glad you like it!
It’s interesting to know that it also seems to work on Framework 16.
I don’t know which speakers the Framework 16 has, and I’m quite certain that the Framework 16 chassis has quite different resonance frequencies. Perhaps @Kieran_Levin has the resonance frequencies for the Framework 16 and could provide them?
As I don’t have a Framework 16, I can’t provide a preset. If there is someone in Vienna with a 16, I would love to hear it and try to get the most out of it!

Thank you for the preset! I ported this over to easyeffects on linux. Works like a charm. Significant increase in audio quality. Not as good as a macbook though, but I wasn’t expecting that much haha.
I believe the creator of this preset was actually Philonmetal, you can see some posts above Speakers sound quality - #63 by Philonmetal and thelitedragon kindly made it into and APO preset for Windows users.

Kieran, I am wondering with the ALC295 if there is hardware equalization available and if framework is already using it? This I believe would be accessed via the registers one can already change with hda verbs? It would be much better if we could tweak the hardware equalization right on the codec instead of wasting so much CPU on tuning the speakers with software.
I haven’t been able to get my hands on a ALC295 datasheet online to confirm but even codecs from 2006 have this feature and the Tempo 92HD95B also has it.
Edit: The 92HD95B shows that there is a 5 band per side hardware eq you can setup via the EQ_COEFs. Someone with a board with this codec could potentially mess with this I think.

which platform?
Latest 13 and 16in platforms enable some limited EQ in hardware.
I am on the FW13 AMD mainboard. Would be amazing to have information about the hardware equalization registers as then we could tweak them easily with hda-verbs afaik.
Are you saying that there is some enabled HW EQ currently on AMD mainboards? Don’t want to start trying to diff the two platforms haha
Yes, both 13 and 16in AMD platforms have some hardware EQ features enabled.
Would it be possible to get the information about the parameters/coefficients implemented so that we could tune the hardware EQ via hda-verbs?
Here is an example from the Linux verb on the 16in Notebook:
Disable EQ

Very interesting. I’m scratching my head right now on the format though. Wasn’t what I was expecting. Any context around how that is being applied?
this should just be formatted into a byte array, which you should find matches the verb table in memory.
Are they packed verbs? 0x0nnvdddd
nn = node
v = verb
dddd = data
I don’t have access to a FW16 only a FW13. I think the FW16 also has an additional IC for the second set of speakers. I don’t have any nodes at 0x050 on here.
Edit: They do look like pairs of 0x5 + 0x4 verbs but maybe it’s just the node throwing me off from the Fw16 setup
Edit2: Oh looks like the format is similar to this reference https://temposemi.com/wp-content/uploads/docs/92HD95_mobile_ref_sch_verb_table.txt
I have a feeling that this is supposed to be
Disable EQ
dd 05350000h
dd 0534219Ah
dd 05450000h
dd 0544219Ah
To turn it off on each side? Else it’s just setting the same data twice. Do you happen to have the same thing for the FW13? I wonder what that is going to look like node wise.
I wasn’t able to figure out a way to dump the same stuff on Windows yet to see if the driver does anything. Are these hda verbs set in the bios on these models?
Any chance to get the verbs for the 13? Any chance to get documentation about the verbs or that section of the datasheet for the ALC295?
Haven’t heard back in 26 days so I thought I’d reply again. Maybe there isn’t tuning on the 13? Thanks
For the AMD 13in using the realtek codec, this is the part cut out related to the EQ configuration:
//ALC295 EQVerbtable

@parawizard Looking forward to also directly trying setting up the hardware codec, but do not know how to utilize the published verbs.
If you could share, a script I guess

Well. Have to figure out how the verbs work so we can change this values. Setting them is not difficult no published datasheet that I know of and it’s not standard. We may be able to find a similar datasheet with a similar implementation. There is going to be x number of eq bands with a value for frequency, potentially a qfactor and db change. That will be per side likely as the speakers arent symmetric iirc.
