About this tool, tips & FAQ

What is bitrate?

Bitrate describes how many kilobits of audio are processed every second. Higher bitrates typically retain more detail in the recording, while lower bitrates reduce fidelity but produce smaller files.

What are recommended bitrates?

For spoken word, 64 or 96 kbps is often sufficient, while general music works well between 128 and 192 kbps. High-fidelity needs, such as streaming or archiving, usually target 256 or 320 kbps, but the best value depends on your audience and storage constraints.

How does quality compare to size?

Increasing the bitrate improves audio quality but also increases the file size. There are diminishing returns above certain thresholds, so balancing bitrate with how much storage or bandwidth you can afford ensures you don’t overdeliver bitrate where listeners can’t distinguish the difference.
