    MOD is a computer file format used to represent music, and was the first module file format. MOD files use the ".MOD" file extension, except on the Amiga where the original trackers instead use a "mod." prefix scheme, e.g. "mod.echoing". A MOD file contains a set of instruments in the form of samples, a number of patterns indicating how and when the samples are to be played, and a list of what patterns to play in what order.

    A pattern is typically represented in a sequencer user interface as a table with one column per channel, thus having 4 columns; one for each Amiga hardware channel. Each column has 64 rows.

    A cell in the table can cause something to happen on its column's channel when its row's time is reached:

    Start an instrument playing a new note in this channel at a given volume, possibly with a special effect applied on it

    Change the volume or special effect being applied to the current note

    Change pattern flow; jump to a specific song or pattern position or loop inside a pattern

    Do nothing; any existing note playing in this channel will continue to play

    An instrument is a single sample along with an optional indication of which portion of the sample can be repeated to hold a sustained note.

    In the original MOD file the minimum time frame is 0.02 seconds, or a vertical blanking, because the original software used the VSync of the monitor running at 50 Hz (for PAL) or 60 Hz (for NTSC) for timing.

    The rate at which pattern data is played is defined by a speed setting. Each row in pattern data lasts one vertical blanking (or 0.02 seconds) times the current speed setting. The speed setting varied from 1 to 255. In later versions of the format, the vertical blanking was replaced with an adjustable time period staying in range [0.001, 0.078] seconds. The old speed setting command was replaced with a new one that was used to change both the old speed setting and the new adjustable time period. Unfortunately, some of the old functionality was broken, because the new speed setting command had identical code value to the old one. Values in range [1,31] were interpreted as old speed settings, but other values were regarded as modifications to the adjustable time period. Hence, values in range [32, 255] used in some old songs broke in new versions of the player.

    For more info about the MOD format see the alt.binaries.sounds.mods FAQ.

    MOD is also the file extension for the video file format used on many camcorders, such as the JVC Everio, and the Panasonic D-Snap SD-card camcorders.

    It appears that you can just rename the MOD file extension to MPG as it appears to be a standard MPEG-2 file. Then the file is compatible with players and other software tools that can read Dolby AC-3 Surround Stereo encoding.

    MOD also happens to be the file extension used by the Neverwinter Nights game for game modules. This has been known to cause some confusion, as NWN modules are not playable in a music player.

    其實點開 .mod 好視乎你個file本身係裝咩既.

    我諗你可以先試下轉左個file extention 做 .mpg 先.


    如果唔得你再話比我知啦 :)
