Bitrate vs sample rate: two different audio measurements
Sample rate describes measurements per second in sampled audio; bitrate describes encoded data per second.

Quick comparison
| Question | First option | Second option |
|---|---|---|
| Unit | Hz or kHz | kbps or Mbps |
| Applies to | Sampling process | Encoded stream |
| Higher means | More samples | More data allocation |
| Quality effect | Depends on source and workflow | Depends on codec and source |
How to choose
- Do not use bitrate as a substitute for checking the source codec.
- Match sample rate to the project and bitrate to the delivery constraint.
The right choice follows the source and destination. Converting a lossy source to a larger file does not recover removed information, while keeping a lossless master leaves future delivery options open.
