Free online MED to OPUS converter

Source format: MED

MED is a tracker music module format associated with the OctaMED family of music software, originally popular on the Amiga platform. A MED file typically stores pattern-based music data, instrument definitions, samples, and sequencing information rather than a finished audio recording. It is used by musicians and retro-computing enthusiasts for composing and preserving tracker music, especially where the original arrangement and sample structure need to be retained.

Because MED is a project-style music format, it is best suited for editing and playback in compatible tracker software. It is not as universally supported as common audio formats, so conversion is often needed when you want to share the music broadly or play it on standard devices.

Target format: OPUS

OPUS is a modern compressed audio format designed for efficient storage and high-quality playback, especially for speech, music, and streaming. It offers excellent compression efficiency, low latency, and strong quality at low bitrates. OPUS is widely supported in browsers, VoIP tools, messaging apps, and many media players.

The main advantage of OPUS is that it turns a tracker module into a standard audio file that is easy to play almost anywhere. Unlike MED, OPUS does not preserve editable patterns or instruments; it stores the rendered audio output only.

How to perform the conversion

The most reliable way to convert MED to OPUS is to first render the MED module to audio, then encode that audio as OPUS. In practice, this usually means using a tracker player or converter that can open MED files, followed by an audio encoder such as ffmpeg.

1. Open the MED file in compatible software. Use a tracker or module player that supports OctaMED files, such as OpenMPT, XMPlay with the right plugins, or a dedicated Amiga tracker emulator/player if needed.
2. Render or export to WAV/FLAC. In the software, look for File → Export, File → Render, or File → Save as audio. Export to an uncompressed format such as .wav or a lossless format such as .flac to preserve quality before encoding.
3. Encode the audio to OPUS. Use ffmpeg to convert the rendered audio file to OPUS. For example: ffmpeg -i input.wav -c:a libopus output.opus
4. Adjust quality if needed. You can set a target bitrate such as -b:a 128k or use a variable bitrate setting for better efficiency. Example: ffmpeg -i input.wav -c:a libopus -b:a 160k output.opus

If you prefer a simpler workflow, you can convert the file on 101convert.com for free without installing any software, provided the site supports the specific MED file variant you have.

Notes on quality, compatibility, or limitations

MED is not a direct audio format, so conversion to OPUS is always a rendering process. That means the result depends on the playback engine, sample handling, tempo interpretation, and any effects supported by the software used for rendering. Different players may produce slightly different audio.

Because OPUS is lossy, it is excellent for distribution and playback but not ideal if you need to preserve the original module for future editing. For archival purposes, keep the original MED file and, if possible, a rendered .wav or .flac master alongside the OPUS version.

Compatibility is generally very good for OPUS in modern software, but some older hardware players and legacy systems may not support it. If maximum compatibility is required, consider also keeping an MP3 or AAC version in addition to OPUS.
