Audio bitrate意思

"Audio bitrate" is a term used in digital audio encoding to describe the number of bits that are processed per second in a digital audio stream or file. It is a measure of the amount of data that is used to represent the audio content, and it directly affects the quality of the audio.

Higher bitrates typically result in better audio quality, but they also require more storage space and bandwidth to stream or download. Lower bitrates can result in a reduction in audio quality, but they take up less space and require less bandwidth.

The bitrate is usually expressed in kilobits per second (kbps) or megabits per second (Mbps). For example, an audio file or stream with a bitrate of 128 kbps would use 128,000 bits per second to represent the audio content.

In the context of digital music files, common bitrates for MP3s range from 128 kbps to 320 kbps, with higher bitrates generally providing better sound quality. For streaming audio, the bitrate can vary depending on the quality setting chosen by the user or the limitations of the user's internet connection.
