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 ...

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 ...

Can a digital sound wave take any shape?

A perfect sine wave can only be one shape as it is derived from geometry: So it always sounds the same. But yes, a wave can take any shape and this affects the timbre. An interesting point however, ...

Can a digital sound wave take any shape?

According to theory, all complex sound waves can be decomposed into a set of sine waves, which are the most basic of wave shapes. Two sine waves of the same frequency will be identical except possibly ...

Pulse wave duty cycle

What makes a signal audible is it's variations, not it's absolute level. Both examples you mention (0% or 100% duty cycles are in fact DC signals, either at 0 or full voltage) can therefore not be ...

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 (...

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 ...

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 ...

Do digital oscilloscopes display timbre or fundamental waves?

You have a slight misunderstanding of what a wave is. Your ears (or an oscilloscope) will hear the sound of pressure increasing and decreasing. That's what sound is. The air in your ear can really ...

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 ...

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 ...

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 ...

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 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 ...

Pulse wave duty cycle

Sound is generated from signals based on movement of a speaker cone. The cone responds to the voltage applied resulting in a magnetic field that drives a magnet to push the cone. The movement of the ...

Can a digital sound wave take any shape?

The only shape a digital sound wave can not take is a perfect square wave (or impulse but its the same issue). This is a mathematical limitation caused by the electronics them selves. They simply need ...

Can a digital sound wave take any shape?

Can a digital sound wave take any shape? Now, there's no such thing as a digital sound wave. But most digital (16 bit wav 44.1kS/s, 24 bit wav 48kS/s, and higher quality) will get you VERY CLOSE to ...
