Relationship between amplitude and loudness (again)?
Amplitude is an objective measurement. In a waveform, it is the value of the y axis at any given point in time.
Loudness is a subjective measurement, based on how we perceive amplitude and other ...

How does a cardboard paper towel roll amplify the sound?
Quite an interesting project indeed.
The paper towel roll and cups are are working as an acoustic megaphone, also called (in ancient times) speaking trumpet.
Directional focus of the radiating sound ...

How do sound waves work that make certain intervals sound good?
Simple frequency intervals generally sound good. Our auditory processing parts of our brains appreciate simple relationships. A perfect fourth has a 4:3 frequency ratio and a diminished fifth (...

Effect of sound waves striking an object
Interesting topic!
If you first imagine that sound waves emanating from a point source (which you are going to have to approximate as a speaker) will emit spherically. Where the sphere intersects ...

On proper use of Waves L2
Always run it as the very last plugin in the chain.
Even if you are going to be sending the mix away for mastering, setting both threshold & out ceiling to -0.3 will just prevent overs.
If ...

What makes these "sweeping" artifacts happen in high pitched audio?
Those are sampling artifacts. The sample rate is too low to cope with the frequencies involved so you get aliasing distortion, where the artificial elements of the digital signal (high frequency ...

Shape and dimensions of a parabolic cone for effect soundwave redirection
Aside from downward facing subwoofers, where there is not really a need for a diffuser, the only "audiophile-ready" loudspeaker that is similar to what you ask is the Citation X by Harman ...

How do I use Impulse Responses from Waves in another convolution plugin
The reason that Waves store the files in a 'wir' format is to make them proprietary, thus preventing you from using them elsewhere. You would have to reverse-engineer the 'wir' file format, extract ...

Threshold and Out ceiling in Waves L2
Assuming it is the last plugin in your chain & you're using it it as a 'mastering leveller' then I'd set the out ceiling to just under zero. I find -0.3 avoids nasty crunching even on cheap ...

How does a cardboard paper towel roll amplify the sound?
Pitch content that roughly matches the resonance tendencies of the shape will also get a boost relative to the other frequency content. The resonance frequencies of the tube are probably very limited, ...

How do I recreate this detuned synth?
I already made a pluck sound in Serum some time ago that is similar to this. To recreate something more like your sound I modified my existing pluck like this:
When using these waveshapes you might ...

What gives a square wave harmonics, and not a sine wave?
You're looking at it the wrong way round.
The square sounds like it does because it is made up of a fundamental frequency and a series of harmonics, whereas the sine wave just has the fundamental ...

Shockwaves: loudness or speed?
Your research is heading in the right direction, but you should firstly understand that as an absolute measurement metric, the "decibel" is meaningless. It's like asking someone "how long is that ...

How do sound waves work that make certain intervals sound good?
Particular intervals don’t sound good — they sound familiar.
It all comes down to what you are used to. Which intervals were used in most of the music you have heard in your life, depending on its ...

Solving for Amplitude and Frequency in WAV files
I'm not sure I understand the question, but you can use the Fourier transform (https://en.wikipedia.org/wiki/Fourier_transform) to decompose any signal into its constituent frequencies. The result ...
