Speed up or slow down your audio files without changing pitch (if possible). This page is designed for people who need to change audio playback speed. Use the controls above to complete the task and review the result before using it elsewhere.
Try a short spoken sentence at a slower and faster setting and check intelligibility.
Depending on the method, changing speed may also change pitch. Confirm the output duration and sound quality. Supported formats, processing limits, and output quality depend on the controls and services available on this page. If an operation fails, try a small supported sample and read any error message rather than assuming the file was processed.
Before using private, confidential, or business-sensitive material, review the processing note shown by this tool and the ArfaAI Privacy Policy. Some tools may use browser features, external libraries, or third-party services; do not assume every workflow is local-only. Keep an original copy of important files until you have verified the result.
Use the example above with a small input, compare the result with the original, and reopen any downloaded file in a compatible application.
Confirm the input type, required fields, browser permissions, and file size. If an external service is used, it may also be temporarily unavailable or rate-limited.
Review it first. Check accuracy, formatting, file integrity, and any rights or privacy obligations that apply to your content.
