The amount of data processed per second in an audio file, usually measured in kbps (kilobits per second). Higher bitrate means better quality and larger file size.
The number of audio samples captured per second, measured in Hz. Common values are 44.1 kHz (CD quality) and 48 kHz (video standard).
Audio can be mono (1 channel) or stereo (2 channels). Stereo offers a more immersive sound experience.
Encoding mode where the bitrate stays the same throughout the entire file. Predictable file size, lower efficiency.
Encoding mode where the bitrate varies based on audio complexity. Higher efficiency and potentially better quality at the same average bitrate.
A type of compression that removes some audio data to reduce file size. Formats like MP3, AAC, and OGG are lossy.
Preserves 100% of the original audio data. Formats like FLAC and ALAC are lossless and ideal for archiving or editing.
An uncompressed audio format offering high quality but large file size. Suitable for editing or archiving.
A lossless compressed format that maintains original quality while reducing file size. Great for storage and high-fidelity playback.
The most widely supported audio format, using lossy compression to balance quality and size. Ideal for casual listening and sharing.
