Filename Structure
The sound files recorded in FlashMic are .wav files, with filenames made up of three
concatenated components separated by underscore characters as follows:
MIC NAME_BWF FILE NAME_TRACK NUMBER.wav
The three components of the filename are specified in FlashMic Manager as part
of a preset definition. After the configuration file containing the preset parameters
is uploaded to the FlashMic, some of the textual data that was entered in FlashMic
Manager is used to form part of the filename.
The three components of the filename are derived as follows:
MIC NAME – this is the name set in FlashMic Manager at Settings>Set
DRM Name. This name applies to all presets defined for a particular
configuration file. In an organisation using mulitple FlashMics, it allows
each to be given an individual name, which might be MIC_nn, for example,
or possibly a recordist’s name (if recordists always use the same FlashMic).
The maximum length of the Mic Name is 6 characters (alphanumeric only).
BWF FILE NAME – this is the name entered in the File Name field (in the
BWF/MPEG File Info area) of FlashMic Manager. This field can be set
differently for each preset in a configuration file. This field can be utilised
in a variety of ways depending how the FlashMic is to be used; one
possibility might be to create presets which differ only in the file name,
relating textually to different interviews that the FlashMic is to be used
for on a particular day. The maximum length of the File Name is 31
characters (alphanumeric only).
TRACK NUMBER – this part of the filename is generated within
the FlashMic itself, and is simply the number of the recording, which
automatically increments by one every time a new recording is made.
It is displayed as TRKnnn in the FlashMic LCD. The format of the track
number is also TRKnnn, where nnn is the track number. Note that the
track number does not reset to zero when a different preset is selected in
the FlashMic, when a new configuration file is uploaded, nor when the sound
files are downloaded. Reformatting the memory (see section Reformatting
the Memory for more information) does reset the track number counter.
Some examples of sound file filenames are shown below.

In the example, several files are in the FlashMic’s AUDIO folder. The first of these is
named MIC_01_JOHN_TRK001.wav.
In this filename, MIC_01 is the FlashMic name that was set in FlashMic Manager
for the configuration file loaded into the FlashMic.
JOHN – possibly the recordist’s name - is the BWF/MPEG File Name set in FlashMic
Manager for one of the presets. We do not know from the .wav filename which
preset number this was, but ‘John’ would have had this information, and would have
selected this preset.
TRK001 is the track number – the first recording of the day, perhaps.
