What is sample rate and why does it matter?

Sample rate is the number of audio samples per second. It is separate from bit depth and codec bitrate. Browser audio may be resampled during decoding or processing, so the rate of an exported file can differ from the source's rate without changing its intended playback speed.

Try this workflow

1. Check the output rate when importing into another audio project.
2. Let the receiving project handle normal sample-rate conversion.
3. Listen to pitch and timing after import if something sounds wrong.

What to check before you finish

SurStudio's AI separation works at 44.1 kHz internally. Increasing a low-quality file's sample rate does not add missing musical detail. For collaboration, agree on project settings rather than assuming every file uses the same rate.

A practical example

An AI output at 44.1 kHz can be imported into a project working at a different rate using normal sample-rate conversion. The intended tempo should remain the same. If it plays unexpectedly fast or slow, check how the receiving program interpreted the file instead of changing its extension or assuming the model changed the song speed.

More questions

Does a higher sample rate always sound better?

No. Recording quality, conversion and the actual content matter; a higher number alone is not a quality guarantee.

Is codec bitrate the same as sample rate?

No. Bitrate describes data per unit of time, while sample rate describes samples per second. Neither number alone establishes the quality of a recording.
