What Is The Difference Between Sampling Rates and Bit Rates?

What is audio sample rate? Audio sample rates are the number of samples per second in an input signal. They can be used to convert between formats, for example, from 48khz pcm or 44100hz wav to 24bit float and back again if you need it.

In this article, we’ll explain why there’s a difference between these two values so that when you’re ready to start making music with your computer, you know exactly how much data you have available in which format.

Why do I need to understand the audio sample rate?

if you’ve made any sort of recordings using a microphone then you probably already know about sampling – but did you ever wonder just how many times every single sound wave gets recorded? The answer might surprise you! Sampling comes into play whenever someone records their voice onto a piece of media like tape, cd or mp3. When recording something digitally you get no choice over whether you record everything at once as one big file or break down each individual note that makes up the song into smaller chunks called ‘frames’. This means that every time you press Record the sound waves being emitted by whatever source you’re recording will be broken down into frames and written out to disk/memory card, etc.

What Is Audio Sample Rate?

In order to properly process audio digitally, you need to know how many samples per second your input has. This number is called the sampling frequency. The way this works in practice is by taking a short time slice from your signal at regular intervals when reading the data off of disk, transmitting over the network, etc. Then you can make calculations based on that very small chunk of information. If the original signal was sampled at 44100Hz, then every 1/44000th of a second would represent a new value. These values could either be positive or negative depending upon whether the sound wave is rising or falling at any given moment. We call all of these points in time “samples” because the word itself means something like cross-section or section. A single piece of music might contain hundreds of thousands of samples, so that’s why we refer to them as frames rather than notes. You may also hear the term “bit depth” which refers to how much precision each sample contains; 8 bits gives us 256 possible levels whereas 16 bits gives us 65 536 possibilities. However, if you take just two adjacent samples, you get 32 different combinations instead of 64. So while we say that our system uses eight bits of resolution, it actually does 10 times better!

What is the audio bit rate?

Audio Bit Rate is a measurement of how much information your digital file contains per second. The more bits that are used to store an amount of data, the greater the quality of sound you will hear from it. At 16-bit resolution, for example, each individual color channel uses 8 bits while the Red, Green & Blue channels use 4 bits each. This means there are 24 bits for every single pixel on the screen. If we move up to 32-bits then double our number of colors with better picture quality. In this case, each pixel would take 2 bytes which equals 16 bits. A good rule of thumb to follow is Quality vs Quantity! So if you’re looking to make high-definition videos just keep increasing the size of your files until they become too large to handle. But don’t forget about the quality factor as well. You can always lower the bit rate without compromising image quality.
