Hi guys, can you help me please. I don’t get why my sub and snare peak together. Theyr freqs don’t overlap at all.
Is it bug, or wotefak?

video has no sound, but hope you get the thing

 

on pro-q3, you are showing a one bar sub bass note for the whole bar. when your kick hits, it is hitting with the same amplitude; relatively.

You are looking at Saturate and seeing the spike of the kick's initial transient rolling off after it happens. the peak is the same approximate 2 parts, equal in amplitude. Therefore, the overall level is doubled, roughly.

What are you seeing that is unexpected to you? You have 2 audible events occurring at the same time, and they are being summed in loudness.

Equation to add the dB volume of two simultaneous events in dB SPL?

Spoiler

To add the dB volume of two simultaneous events in dB SPL (Sound Pressure Level), you can use the formula for adding sound pressure levels in decibels. When two sound sources are combined, the total sound pressure level is calculated as the sum of the squares of the individual sound pressure levels, and then taking the square root of that sum.

The formula is:

�total=10⋅log⁡10(10(�1/10)+10(�2/10))Ltotal=10⋅log10(10(L1/10)+10(L2/10))

Where:

• �totalLtotal is the total sound pressure level in dB SPL.
• �1L1 is the sound pressure level of the first event in dB SPL.
• �2L2 is the sound pressure level of the second event in dB SPL.

You can plug in the values of �1L1 and �2L2 to calculate the total sound pressure level, �totalLtotal.

Thanks for reply! Maybe I don’t know something ngl. If it was bass and kick — no surprise, they have the same low freqs, which doubles them, but here I have snare (without any lows). Why it doubles? Sorry if it stupid question.
It just bothers me in whole mix, when snare and claps have the highest peak (even higher than kick, bec its side chained to bass). I am stuck here tbh

 

have you tried reverse the polarity of one of them ?

 

yep, no difference

 

They don't need to have the same frequency. Different frequencies sum up in the same way.

 

ohh, I definitely have a gap in my technical knowledge right here. Thank you

 

I would agree with @clone . It's probably a pure volume (loudness) thing rather than a frequency one.
So tweaking with the volume should fix it.

 

If you live in South Dakota, and take a small handgun down to the gravel pits to shoot the family dog and a shotgun for the goat.

Remember safety glasses. The little handgun has a high pitched bang! sound, and the shotgun is a nice bassy boom! sound. If you pull both triggers at the same time, will it be louder than only one of them?

x+y=z. next audio math lesson, calculating turns ratio and inductive reactance? Who writes these lessons?

calculating turns ratio and inductive reactance

ChatGPT

Spoiler

To calculate the turns ratio (�N) and inductive reactance (��XL) of a transformer, you need to know the number of turns in the primary (�1N1) and secondary (�2N2) windings, as well as the frequency (�f) and inductance (�L) of the coil.

1. Turns Ratio (�N): The turns ratio is the ratio of the number of turns in the secondary winding to the number of turns in the primary winding. It is calculated as:

�=�2�1N=N1N2

1. Inductive Reactance (��XL): Inductive reactance is the opposition that an inductor presents to alternating current due to its inductance. It is calculated using the formula:

��=2���XL=2πfL

Where:

• �1N1 = Number of turns in the primary winding
• �2N2 = Number of turns in the secondary winding
• �f = Frequency in Hertz (Hz)
• �L = Inductance in Henrys (H)

You may need to adjust units (e.g., Hz to kHz) depending on the given values.

Um, because everything is summed into a single wave? Like, mathematically, a sound within a DAW is a two-dimensional graph, where X goes from 0 to whenever and Y goes from -1 to 1. When two sounds are played together at the same time (have the same X value), their Y values get just straight-up summed up. Like, arithmetically.

 

Unfortunately, I live in a country where guns are illegal. Therefore I couldn’t get this knowledge from guns
Thanks for reply! Got it.
