Introduction to the Audio Speed Changer Tool:

1. This tool allows you to adjust the playback speed of audio files in bulk online, supporting speeds ranging from 0.5x to 2x, and generates new audio files for download to your local device.

2. How to use the tool:

(1) First, upload the audio files whose playback speed you want to adjust. Batch uploads are supported.

(2) Drag the slider with your mouse to select the playback speed you want to adjust.

(2) Click the "Start Processing" button. The tool will begin batch processing, and the progress will be displayed in real time.

(3) Once the audio processing is complete, "Download" and "Preview" buttons will appear; you can preview and download the files as needed.

(4) Processing speed depends on the size and format of the audio files you upload; please be patient while the tool processes them.

3. Audio reverse processing is performed entirely within your browser; your audio files will not be uploaded to the server, so you can use this tool with confidence.
