The bit depth allows for greater nuances to be captured. The higher sampling rate results in less fake samples making their way into an average person’s hearing range. These lossless audio files have a higher sampling rate and greater bit depth. This moves it further from our hearing range resulting in cleaner sounding audio. By increasing the sampling rate you move the low-pass filter higher into the frequency range. Anything above that will introduce fake samples which is where the low-pass filter kicks in to process them out. For example, if the sampling rate is 44.1kHz anything below half that will be accurately rendered. This filter processes out frequencies that are not within the sampling limit.
Analog to digital converters have an in-built low pass filter. There are instances where a higher sampling rate does help to improve the listening experience. The question often comes up if this is needed. Hi-resolution audio can be recorded at double the standard CD rate or even as high as 192kHz. This hasn’t stopped people from recording at a higher sampling rate. Nothing that you would realistically hear. By doubling that you can assume that nothing relevant is lost when recording/reproducing the original sound. The human hearing range tops out at about 20kHz. This theorem determined that if you double the maximum frequency of the source you can accurately capture the sample. This all stems from the groundwork laid out in the Nyquist–Shannon theorem. For example, CDs have a sampling rate of 44.1kHz. The sampling rate is the number of samples taken in a second. Audio bitrate is usually the primary way to determine the sound quality of files but there is more to it than meets the eye….or should I say ear.īitrate is determined by the sampling rate and the bit depth. To understand the battle between 24 Bit and 16 Bit we need to cover how sound functions and more importantly how we hear that sound. There has been much debate about whether the difference between the two is really that important. But there are audio files that are at 24 Bit. You may have noticed a pattern above when covering bitrates. They are still used heavily by streaming services and digital music platforms. It made them easier to share across slow internet connections. MP3s became extremely popular in the early days of the internet due to their low file size. This does result in a reduction in sound quality but also a big reduction in file size. MP3s use a compression codec that removes frequencies while trying to preserve as much of the original recording as possible.

The highest quality MP3 bitrate is 320 kbps at 16 bit. The general trend has moved towards internet-based music distribution methods. From there CDs rapidly replaced compact cassettes as the standard for the sale and distribution of audio recordings. After a few discussions on details, it was adopted as a standard in 1987. This was first established by Philips and Sony all the way back in 1980. CD Audio BitrateĬDs have a bitrate of 1,411 kbps at 16 bit. Now let’s look at some common files you’ll likely have encountered and dive into the details of their respective audio bitrates.

More kilobits equals more data stored across the full frequency range. It will also be defined by the crispness and clarity of high frequencies. For the average listener, the quality will be defined by the strength and depth of low frequencies. The more kilobytes that are stored per second the higher the sound quality of the file. For example, a 128 kbps (kilobits per second) file will have 128 kilobits stored for every second of audio. When it comes to sound files this is calculated by the number of kilobits of data per second. Every second of an audio recording contains a certain amount of data or bits. Every audio file has a “bitrate” associated with it. What Is Audio BitrateĪudio bitrate defines the amount of data that is stored in the sound file you are listening to. But how much do you really know about the sound you are hearing? In this guide, we cover how sound works in the modern age and give you a definitive outlook on how you can enjoy sound more. From our mobile phones to TVs to the music we play. With the explosion of modern technology, we are now constantly surrounded by sound. From the very first time that humans have been able to record sounds, we have wanted to share those recordings with the world.
