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. Now let’s look at some common files you’ll likely have encountered and dive into the details of their respective audio bitrates.īitrate is determined by the sampling rate and the bit depth. 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. From our mobile phones to TVs to the music we play.īut 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.

With the explosion of modern technology, we are now constantly surrounded by sound. Using platforms like Spotify, Soundcloud and the best DJ pools, artists can share their creations with ease. From the very first time that humans have been able to record sounds, we have wanted to share those recordings with the world.
