Does sound lose quality if sped up and then slowed down back to normal speed?

It depends what method is used. If it's simply played back 'faster' without actually changing the data, then of course there is no lasting damage. This would be how a simple sampler would ordinarily ...

Need help to understand the basic components of sound

The highly simplified answer is that sound in the real world is not sine waves with fixed frequencies. We learn about sound initially as frequencies or notes and simplify the concept down to thinking ...

Need help to understand the basic components of sound

Ok, let's start from the basics. Audio is usually recorded (sampled - converted from a continuous analogue signal to a digital record) and stored as a series of numbers representing the momentary ...

does obstacles in front of sound work bidirectional?

Yes. This is all to do with wave interaction. Wave sources and sinks operate independently of each other, even when waves interact with each other and with the medium through which they travel. This ...

What's the science behind acoustic dispersion?

When there's shear waves (like in an ice layer or a steel rail, the high frequencies travel faster than the low frequencies due to higher shear wave speed. A sound impact source results in a downward ...
