Converting your recording format
If you want to keep your recordings in .mmb format but process your data in .imb format, you can convert .mmb files to .imb files using a batch conversion utility.
Context
The M3 software records sonar data in two formats — raw element data (.mmb) or beamformed data (.imb).
If you wish to convert a selected clip of data, you can play back an .mmb file and record the clip as an .imb file. However, if you wish to batch convert many files, a conversion utility is provided with the M3 software.
Note
If files are recorded in .imb format, they cannot be converted to .mmb.
You can find the conversion utility in the folder C:\KML\M3_V0253\bin\M3Converter.exe.

Procedure
1 Select Recording File to convert a single .mmb recording.
Alternatively, select Recording Folder and Include Subdirectories to convert all your .mmb files.
2 Click the Browse button beside Source to select your .mmb file or folder.
3 Click the Browse button beside Destination to select where you want to save the converted files.
If you are saving a single recording, then you must give the file a name.
Tip
When converting the contents of a folder, the files will automatically be renamed. However, we recommend selecting different source and destination folders to avoid filename duplications.
4 Click Convert.
A dialog box will notify you when the file conversion is complete. Click OK to dismiss it.
