Summary (IA Generated)
On a fundamental level, sampling rate is a result of the digitization of audio.
While analog sound waves are continuous, digital music is made up from lots of small data points played one after another.
Sampling rate in audio is literally the number of “samples” taken per second.
Now, the common rate is that of CDs or FLAC, which is a lossless audio file.
What this means in practice is for every second of music, 44,100 samples are taken from a continuous analog signal in order to create a digital file.
This is useful visualization tool, because it clearly shows how a high sampling rate (the wave underneath the x-axis) produces a more precise wave.
All that should have illuminated you on what sampling rate in audio is, but now we have another question….
What impact does sampling rate have on music? e.
the higher the sampling rate, the higher the quality), but it’s not quite that simple.
Sampling rate is directly related to frequency, in other words the highest sound that can be accurately reproduced.
The easiest way to remember it is the sampling rate of audio needs to be double that of the highest frequency that needs to be reproduced.
Do you remember earlier when I said sampling rate impacts quality, but only up to a point? .
The limits of human hearing stretch from 20Hz to 20kHz.
What this means is that CDs and many FLAC files play music with frequencies beyond what humans can hear.
I’m not going to get into this too much (a lot of my view with music is that if it makes you happy, then it’s fine — who am I to judge?), but the science supporting the importance of high sampling rates to listeners is shaky at best, and non-existent at worst.
For recording, high sampling rates canyou can read more about here be a useful tool, mainly due to a whole load of technical details .
Sampling rate can be seen as the audio version of frames per second.
It is the number of “clips” taken from an analogue sound wave in order to make it a digital file.
On top of this, sampling rate also controls the highest frequency that can be accurately reproduced by a digital file.
