Alvaro cid ᑈ Posted October 15, 2023 Share Posted October 15, 2023 Neither the established tone knobs nor the shelving filters, low-pass filter, are sufficient to increase completely freely, since they have a wide roll-off of their own. Therefore I ask, is there a way to integrate some adjustable mode where there is a selectable Starting Point, for example, increase 7dB from 20Hz to 100Hz linearly and be able to manipulate the drop of this by saying that at 100Hz the drop is more closed and end at 130hz. Since if you try to do this with a shelving filter the drop can only be manipulated with the Q factor, however it is not precise since if you set the frequency of (100hz) Q from .8 to 1, let's say that from 20hz to 70hz it increases linearly but from there it has a natural drop according to the Q in this type of filters and ends at a non-visible frequency. and if I set the frequency to 120hz it will increase from 20hz to 90hz approx. linearly, but the drop would also be extended, ending at up to 160hz. What I am requesting could easily be done with the graphic equalizer of 31 bands or more but I have noticed that the bands are not well programmed (?) since if I raise, say, 3 knobs from 30hz to 70hz, these increase frequencies very far from them, checking with An RTA spectrum analyzer shows that it does not raise the frequencies as they should be.

MotleyG Posted October 15, 2023 Share Posted October 15, 2023 Maybe you need to consider a different headphone choice instead? This type of precision from an EQ isn’t really going to fix that. Especially with the parametric options available, if they aren’t sufficient then there is something else more fundamentally wrong there. Link to comment Share on other sites More sharing options...

Este tipo de precisión de un ecualizador realmente no solucionará el problema. Especialmente con las opciones paramétricas disponibles, si no son suficientes, entonces hay algo más fundamentalmente incorrecto. Equalizations of any type are not only corrective, they are also applied to give a tone to personal taste and this is limited by 'x' Equalizer. Now if you are telling me that the solution is to change headphones then If not Correct and Customize the Sound What would the Poweramp Equalizer work like?

Sure you can use any EQ to provide personal taste. But what you are requesting goes far beyond what any traditional graphic or parametric EQ is designed to do. The flexibility and settings in the parametric PA offers is already more than most and certainly can help flavour your sound almost any way you want. If a single band doesn’t give you the precision you seek, add a second band that will sum to get you there. Link to comment Share on other sites More sharing options...

Pero lo que usted solicita va mucho más allá de lo que cualquier ecualizador gráfico o paramétrico tradicional está diseñado para hacer. La flexibilidad y la configuración de las ofertas de PA paramétrico ya son mayores que la mayoría y ciertamente pueden ayudar a darle sabor a su sonido casi de la forma que desee. Si una sola banda no le brinda la precisión que busca, agregue una segunda banda que se sumará para llegar allí. First, I thank you for your response, this helps me learn more about the possibilities of Poweramp. In my case the graphic equalizer would work better but This as an example if I want to boost 7db having as bands 20hz 40hz 60hz 80hz 100hz if I boost 40hz the normal thing for a graphic Eq is that it boosts 7db at 40hz with a natural drop until it reaches 20hz on the left and 60hz on the right but yes I want to do that in the Poweramp graphic equalizer taking the same example 40hz +7db has a drop but it drops beyond 60hz that is the case with all bands. I have verified this with other graphic equalizers and these end up to the frequency that is established on both sides. The problem with the parametric Eq is that if I put a frequency band at 50hz I increase "x" db with "x" Q and add another at 85hz how do I know how many db increase the frequencies that are between said bands such as 60hz or 70hz if I want increase them linearly.

MotleyG Posted October 15, 2023 Share Posted October 15, 2023 Parametric EQs let you adjust the center or cutoff frequency, the width or “Q” of the adjustment, and the amount of boost or cut at that point. There are tons of resources online that explain this in detail. This is far more precise than a graphic EQ with fixed frequency and widths. Try this location for more info https://www.mixinglessons.com/parametric-eq/ Remember that with a lot of boost, you will need to apply a negative preamp gain to prevent clipping your output. Otherwise the limiter will kick in, or worse case you will max out the DAC and the intended EQ adjustments will no longer be as precise. Link to comment Share on other sites More sharing options...

Hay toneladas de recursos en línea que explican esto en detalle. Esto es mucho más preciso que un ecualizador gráfico con frecuencia y anchos fijos. Pruebe esta ubicación para obtener más información https://www.mixinglessons.com/parametric-eq/ Recuerde que con mucho impulso, necesitará aplicar una ganancia de preamplificador negativa para evitar que se recorte la salida. De lo contrario, el limitador se activará o, en el peor de los casos, maximizará el DAC y los ajustes de ecualización previstos ya no serán tan precisos. It has increased up to 15 dB in the parametric eq with a frequency of 120hz with Q.1 as a check and the eq curve is not affected if what it says is true because it only affects the graphic eq and not the parametric eq And I think I'm not being very specific so I leave these graphs This first one is from the Poweramp Equalizer with pink noise, Frequency 120hz Q:1 +15 db Link to comment Share on other sites More sharing options...
Alvaro cid ᑈ Posted October 15, 2023 Author Share Posted October 15, 2023 And this is from the Poweramp Equalizer Frequency 120hz Q:2, that is, no matter how much the Q increases, it does not close in a more abrupt way. In addition, as you increase the Q, an enhancement is created before 120hz and a decrease in front of 120hz and if the Q is lower, which generates more unwanted frequencies to enter.

Alvaro cid ᑈ Posted October 15, 2023 Author Share Posted October 15, 2023 And the latter is from the Sound Tune application. 31-band graphic equalizer has better control over the decay despite being a graphic Eq. Link to comment Share on other sites More sharing options...
maxmp Posted October 16, 2023 Share Posted October 16, 2023 First, this is Poweramp player forum category, not Equalizer, so I’ll move the topic appropriately. As for very precise low frequency bands tweaking in Equalizer it may require increasing Block size to increase resolution of the FFT used in Equalizer app. The whole processed spectrum is evenly divided, and while Equalizer tries to approximate parametric/graphic bands/settings to these fixed FFT bands, you may have like 10hz+ or so resolution, which may not be enough for 100% accurate lower bands. Increasing block size increases resolution, but it also increases cpu load and smearing, so there is a trade off. Link to comment Share on other sites More sharing options...
