What is Audio Bitrate?
Audio bitrate refers to the amount of data processed per second in an audio file, typically measured in kbps (kilobits per second). Higher bitrate generally means better sound quality but larger file size. Common bitrates include:
- 128 kbps – Standard quality
- 192 kbps – Good quality
- 256 kbps – High quality
- 320 kbps – Studio quality (for MP3)
