Glossary

Artifact

Unwanted visual or audio distortion introduced by compression, upscaling, denoising, or re-encoding (e.g., “warbling” in audio, “ringing” in images).

Background noise

Unwanted sound not part of the main subject (hum, HVAC, traffic, crowd, wind). Often reduced with denoising or voice isolation.

Clarity (text)

How easy text is to read and understand on the first pass. Improving clarity usually means simplifying sentences, removing redundancy, and making structure explicit.

Compression

Techniques that reduce file size. Compression often introduces artifacts; refinement workflows commonly aim to reduce the visibility/audibility of these artifacts.

Denoising

Reducing unwanted noise from audio (and sometimes image/video) while preserving the main signal. Over-aggressive denoising can create artifacts.

Dynamic range

The difference between the quietest and loudest parts of an audio signal. Managing dynamic range can improve speech intelligibility.

Export settings

The codec/format/bitrate/resolution choices you use when saving refined output. See Export settings.

Hallucination

AI output that invents details. RefineAI docs focus on improvement workflows designed to minimize unwanted invention—especially for text.

Upscaling

Increasing apparent resolution/quality of images or videos. Upscaling can enhance perceived detail and reduce compression artifacts, but is not perfect ground truth recovery.

Voice isolation

Separating speech from background noise and competing sounds (music, crowd, room tone). Often used for podcasts and interviews.
