Free online MED to AAC converter

Brief explanation of the source format

MED is a family of file formats most commonly associated with music tracker modules, especially files used by the OctaMED and related Amiga-era music tools. A MED file usually stores pattern-based music data rather than recorded audio, including notes, instruments, effects, and sequencing information. It is used by musicians, retro-computing enthusiasts, and archivists who work with classic tracker compositions.

Because MED is a module format, it is not directly playable everywhere without a compatible player or converter. It is often used for preserving tracker music, editing old compositions, or exporting them to modern audio formats.

Brief explanation of the target format

AAC (Advanced Audio Coding) is a compressed digital audio formatgood sound quality at relatively small file sizes, which makes it a common choice for music distribution and portable playback.

Unlike MED, AAC is not editable as musical patterns; it is a rendered audio file. Converting MED to AAC means first playing or rendering the module into audio, then encoding that audio as AAC.

How to perform the conversion

The best approach is to use a tracker/module player or converter that can open MED files and export or render them to audio, then encode the result to AAC. A practical desktop workflow is:

1. Open the MED file in a compatible player or tracker such as OpenMPT, XMPlay, or another module-capable application that supports MED playback.
2. Render or export the song to an uncompressed audio format such as WAV or FLAC. In many programs this is found under File → Export, File → Render, or File → Save as.
3. Convert the rendered audio to AAC using an audio encoder such as FFmpeg. For example, if you exported song.wav, you can run: ffmpeg -i song.wav -c:a aac -b:a 192k song.m4a
4. If your player or editor can export directly to AAC or M4A, you can use that option instead, but a two-step render-then-encode workflow is usually the most reliable.

If you want a simple browser-based option, you can convert the file on 101convert.com for free, without installing any software.

Notes on quality, compatibility, or limitations

MED to AAC is a lossy conversion in the final step, so some audio detail may be reduced compared with the rendered source. To preserve the best quality, render the MED file to a lossless intermediate such as WAV or FLAC before encoding to AAC.

Compatibility depends heavily on the specific MED variant and the software used. Some players support only certain OctaMED-related files, so if a file does not open correctly, try a different tracker or module player. Also, because MED is pattern-based music, the final AAC output will reflect the playback engine’s interpretation of instruments, effects, and timing.

For archiving, keep the original MED file as well as the rendered AAC file. The MED preserves the editable composition, while AAC is best for convenient playback and sharing.
