Parametric EQ with 40 and more filters for TIDAL on Android, Windows, Linux, hardware?

[SashaR]

or even 48?

In first, the hum which was left after following the advice of @staticV3 was caused by using not appropriate filter set - it uses +18 dB to compensate for the hole on 110 Hz that occurs in the listening chair - and my two sleepless days resulted in me NOT using the filter set that is "for the computer chair" while sitting next to the computer [ @Sokel ] .
Please forgive me!!!

In second, setting D90SE to 44.1*24bit did not reduce the hum in this Tidal's track 74948426 (it has a 15 to 110 Hz background noise of -35 to -55 dB) but worsened the sound quality of the 192 kHz track (at least made it quieter).

But my results are not reliable, because at some point (apparently after one of the EAPO reinstallations) the "Original APO" option became inactive:

! Now (after (?) this) the playback of the Windows' test signal played with a shock if D90SE is set to 44.1 (both 16 and 24 bit). !

I couldn't understand the purpose of coloring them red, and instead of -4 dB recommended by the EAPO researcher, I hid the entire curve under zero (-20 dB!) - is I'm wrong?

Red coloring means signal boost above 0dBFS -> digital clipping.


To fix it, insert a Preamp block above all other blocks and reduce until Peak gain <0dB.

Is there a parametric equalizer with 40 or more filters for use with TIDAL - in Android, Windows, Linux or hardware?

In Android, I only know UAPP. It can change the DAC frequency - but it has only 10 filters.

In Windows, I know APO Equalizer with an unlimited number of filters - but Windows generates a hum when the "extra processing" mode is turned on, without which APO Equalizer does not work. In addition, APO Equalizer does not work if TIDAL is in EXCLUSIVE mode, and therefore TIDAL cannot change the DAC frequency when using APO equalizer (how significant is the loss of quality caused by this?)

Maybe in Linux there is no problem with controlling the DAC frequency and there is a System equalizer with 40 filters?

I am very grateful in advance for any advice and help!

I run CamillaDSP on Linux. There is no limit to the number of PEQs and it also can do FIR convolution.

turn down the completely un-necessarily high sample rate. Say down to 96kHz - or even 48

If you, dear @antcollinet , are talking about fixing the frequency of the DAC, then there is a very important "Upsampling Performance" remark about upsampling (I bought a B100 amplifier instead of an LA90 in order to gain 10 dB (go from 140-150 to 160) and then let Windows create 134 dB noise ?..). What happens with downsampling is not written (i.e. if track 192 is sent to the DAC which is fixed at 44.1). If I am demonstrating my lack of understanding with these words, then please tell me, dear @antcollinet , its magnitude!

EqAPO shows strange values sometimes, I don't think it's an issue. I think it goes by theoretical max singal, but usually you will have stuff a lot quieter an this. Example:

I have the boosted the signal +10dB via preamp, but if I look into TotalMix:

So yes, if you plan on playing back a maximum volume signal at 100% volume it might be an issue, but everyday usage, I don't think it is.

High sampling rates only deliver more bandwidth, ie higher frequencies (not more SNR, or anything else measured in dB). And what is it that makes you think you are getting anywhere near 160dB of anything with the B100?

44.1 kHz can already deliver the full 20 kHz that human hearing is capable of. 48 kHz then gives a bit of headroom. Anything more is really redundant - although some people will use 96 kHz - though it is completely unnecessary. Anything more is a real waste of data rate - and in fact, can (theoretically) result in a reduction in quality in the form of IMD in speakers. It also means a much higher processing headroom for DSP - which is the reason for my question - I was wanting you to try a lower data rate to check your system was not causing noise by not being able to process fast enough.

reduce until Peak gain <0dB.

Please explain to me what is written in the information that you recommended to me! Here, in the final "Summary Recommendations", the author wrote:
"... set EAPO's preamp gain at ~ -4 dB". So I added 4 dB to be 4 dB away from zero...

After all, the EAPO cannot work with an exclusively used DAC

I'm right - are -4 dB be must?

Can you, dear @staticV3 , explain why Tidal in Windows sounds different than UAPP in Android -- with the same settings (lack of equalization and bit-perfect)?

 

[SashaR]

near 160dB

I meant the difference in SNR of the two amplifiers: -140\-150 dB for LA90 and -160 dB SNR for B100. Forgive me for my carelessness, please!

Regarding your words about the uselessness of fixing the DAC frequency at 96 kHz due to the uselessness of a wide bandwidth. I posted a link to a story about the distortions created by Windows when increasing the frequency (and there is a link to the ARCHIMAGO study there). And vice versa, if we fix the DAC frequency at 44, then Windows will lower the signal frequency - and, probably, will spoil it when lowering the frequency too. What is your opinion in this matter?

 

[SashaR]

Please forgive my tiredness and haste - and please tell me "which button should I press" in REW to get convolution from the registration file - in case these two files can allow me to get convolution from them? Thank you very much - and once again, please forgive me for my question!

Thank you very much for opening the door to LINUX for me. I am completely new to it, but if I can't get through Windows or Android, I'll have to decide to look in that direction! Does Linux require command lines or can dummies use an interface similar to Windows or Android to play TIDAL with an equalizer?

There are a lot of linux options and variants depending on exactly what it is you're after. For starting I would suggest either an ordinary desktop distribution like Ubuntu or Mint plus EasyEffects, or one of the specialist audio builds that turn a Raspberry Pi or a PC into an audio appliance that you control through a web browser or app. You shouldn't need to use a command line for any of these. I don't know what state Tidal support is in - it's not one I use. I know the paid version of Volumio includes Tidal Connect support, and that a plugin for LMS is under active development.

Use Jriver v34

I tried to try TIDAL with Jriver - and I was unable to remove the catastrophic stuttering when playing 192 kHz. 44 and 96 are played almost without problems.

My repeated attempts to register on the forum were unsuccessful (see), and therefore I took the liberty to contact you with this problem (stuttering with 192 kHz).

 

[Sokel]

Easy with the VC if you're changing from shared to exclusive though, those 20dB will suddenly appear on playback if not set there too.

Unfortunately 192kHz does not work, it is a known issue and they refuse to fix it.....
Not sure why....

Excuse me, please! I didn't understand your advice!

192kHz does not work

And how do you use TINDAL without 192 albums?

 

[Sokel]

Excuse me, please! I didn't understand your advice!

When using EAPO you will have -20dB lower output with windows shared output.

If you switch to WASAPI exclusive or ASIO these -20dB will no longer apply if you haven't set the player's volume control as so.

So be careful with the volume control and check each time.

 

[ppataki]

And how do you use TINDAL without 192 albums?

I only have like 2-3 songs in my collection in 192kHz so I don't mind
But Jriver should fix this bug nevertheless
If more of us push them they might.....

My only problem with Jriver is its non-existing support process. There is a forum where you can ask things that mostly they ignore - really weird, especially in 2025....

 

[SashaR]

If you switch to WASAPI exclusive or ASIO

I'm trying to use EAPO to apply filters to TIDAL. The manufacturer of my DAC (Topping D90SE) gave the ASIO driver (not WASAPI) - but I do not know how to force the TIDAL to use ASIO.

with windows shared output

what is the wind shared output - and why -20 dB ?

 

[SashaR]

Try using EQApo

What should we do to make EAPO switch convolutions by itself, automatically based on the frequency of the piece being played? Should we beg the author of EAPO to implement this (VERY EASY TO IMPLEMENT!) function or write a script using EAPO (if it has such a tool)?

To the plea to the author of the EAPO, I would add a plea to create "profiles" - in my situation, a profile for a single device would be enough for me - but I have to use three different listening points! Therefore, "profiles" are also needed by those who have only one audio device!

But who should I address this plea to? Do you know? Can you help in this situation too, as in many others?

 

[SashaR]

Try using EQApo

Thanks for your advice to use EAPO: with it, using a 39-band PEQ I was able to correct the room and even the modal dip below the Schroeder frequency (two points 6 Hz apart, 24 and 21 dB below target!)!

But it is very difficult to use TIDAL in Windows: it does NOT have an ASIO interface and in order to control the DAC frequency, TIDAL must prohibit the operation of the EAPO! And in order to be able to use a sufficiently powerful PEQ (via EAPO), it is necessary to prohibit TIDAL from controlling the DAC frequency - and this makes it very difficult to use convolution filters!!! Each time the frequency of the material being played changes, it is necessary to manually change the DAC frequency and reboot the EAPO! That is, at least mixes cannot be played using convolution filters.

UAPP allows only 10-band PEQ, EAPO almost does not allow the use of convolution filters... I am waiting for your advice and opinion!!! @staticV3
