MDR File – What is .mdr file and how to open it?

MDR File Format

MDR files are compressed audio module files that utilize the ModPlug Sound System (Mss). They contain digital music data in a lossy format, meaning some quality is sacrificed for a smaller file size. MDR files are typically used for storing and sharing music created with ModPlug Tracker, a popular software for composing and editing music in the tracker format.

The MDR file format employs a custom compression algorithm designed to reduce the file size of the module data while maintaining acceptable audio quality. This makes MDR files suitable for online distribution and storage on devices with limited space. However, they cannot be played back directly by all audio players; specialized software like ModPlug Player or XMPlay is required to decompress and play the audio contained within.

Opening MDR Files with ModPlug Tracker

MDR files are compressed module files used by the ModPlug Tracker, a free and open-source software for creating and editing music modules. To open an MDR file in ModPlug Tracker:

1. Launch ModPlug Tracker and click on “File” > “Open…”
2. In the file browser window, navigate to the location of the MDR file.
3. Select the file and click on “Open.”
4. ModPlug Tracker will load the MDR file and display its contents in the tracker window.

Using Third-Party Software to Open MDR Files

If ModPlug Tracker is not available, there are alternative third-party software programs that can open MDR files:

• Winamp is a popular media player that can play a wide variety of audio formats, including MDR files. To open an MDR file in Winamp, simply drag and drop the file onto the Winamp window or right-click on the file and select “Open with” > “Winamp.”
• Foobar2000 is another free and open-source media player that can play MDR files. To open an MDR file in Foobar2000, drag and drop the file onto the Foobar2000 window or right-click on the file and select “Open with” > “Foobar2000.”

ModPlug Compressed Module (.MDR)

MDR files are compressed music modules that utilize the ModPlug Tracker format. Developed by Olivier Lapicque, ModPlug Tracker is a music creation tool designed for creating and editing module-based music. MDR files are a compressed version of the MPTM (ModPlug Tracker Module) format, reducing the file size for efficient storage and distribution. This compression makes MDR files more suitable for sharing and archiving purposes.

Technical Specifications

MDR files employ lossless compression, preserving the original audio quality without degrading it. They contain musical patterns, sample data, and instrument definitions, enabling playback on compatible software such as MilkyTracker, OpenMPT, and other music trackers that support the ModPlug Tracker format. MDR files can be decompressed to the corresponding MPTM format using tools like MDRDecompress, allowing for further editing and modification in ModPlug Tracker. The small file size of MDR files makes them a convenient option for storing and handling large music modules, particularly in contexts where file size optimization is crucial.
