  1. 01

    Upload your source

    Sign in and upload a local file. Inspection checks the streams and duration.

  2. 02

    The relevant settings section opens after inspection. Review the starting values below.

    Convert and download

    Follow background processing and download the validated output.

The controls you will use

Audio tempo settings

Choose the operation here and it stays selected through registration or sign-in. Upload and inspect your source to open its settings. Starting values are editable; check them against your file before submitting.

Audio tempo

0.25× to 4×; starts at 1.25×.

Trim range

Select the recording portion first.

Output format

Choose an audio profile to retain the changed duration.

What to check before exporting

Large tempo changes can introduce artifacts. In video output, independently changed audio is trimmed or padded to match the video; use Change Video Speed to change both together.

Choose a compatible output profile and review the source streams, selected range and final settings. Processing uses structured controls, and incompatible combinations are rejected before queueing. Download the requested result when final validation completes.

Inside Media Converter

A real workspace. A result you can inspect.

This actual product screenshot shows source playback, range selection, an uploaded-audio area and encoding settings. It illustrates the shared converter; your operation opens its own relevant controls after inspection.

A processed preview creates a separate short task. It covers the first ten seconds of your range at up to 360p in a compatible format. Image and subtitle exports still need inspection of the requested final download.
