An ASX file is a specialised format that is engineered to work in tandem with Microsoft's proprietary video compression format, ASF. As a metafile, it does not contain actual media but functions as a shortcut to a parent file. But since it redirects to the data stored in an ASF file, it is possible to isolate the audio referenced by an ASX file and convert it into MP3 format. Users can take advantage of specialised programs to carry out this task, but this type of file conversion can be performed entirely online. Media Convert is a comprehensive, free-to-use application that can re-format an ASX file as an MP3 file. It is operated through an internet browser and does not require the installation of software. While other online conversion tools like Zamzar, Movavi Online Convert and online-Convert exist, Media Convert is the only one that supports ASX as an input file format.

Open your internet browser and access Media Convert.
Upload your ASX file for conversion into MP3 format. Click on the "Local File Conversion" tab. Click on the "Browse" button next to the "File" field. Navigate to your ASX file in the file selection window. Double-click on the filename and it will load into the online conversion tool. Open the "Input Format" from the drop-down menu and select "Video Stream Descriptor (.asx)."
Initiate the MP3 conversion. In the "Output Format" section, leave "No Video Preset" selected in the first drop-down menu. Go to the second drop-down menu and choose "MPEG 1/2 Audio Layer 3 (.mp3)." Hit the "OK" button. The ASX file will be uploaded to Media Convert and the conversion will begin.
Download your converted MP3 file. A confirmation message will appear when the conversion is successful. The user will be redirected to a page to download the converted file. Click on the MP3 filename and follow the instructions in the "File Download" dialogue box. Once it is downloaded to your desired location, the MP3 file will be available for use.
Tips and warnings
- Users can take advantage of Media Convert's "Advanced Settings" module to program ID tags for the MP3 file. This type of metadata can be used to convey essential information about the audio track, such as title, artist, album, release year and track number. Users can also manipulate the volume of the MP3 output in this section.
