Bitrate refers to the amount of data processed in a given amount of time, typically measured in bits per second (bps). It is a crucial factor in determining the quality of audio and video files. Higher bitrates generally result in better quality, as more data is used to represent the sound or image, while lower bitrates can lead to compression artifacts and reduced clarity. In digital media, bitrate can vary depending on the format and compression method used. For example, streaming services like YouTube and Spotify adjust their bitrates based on internet speed to provide a smooth experience. Understanding bitrate helps users choose the right settings for their media consumption.
