I strongly believe that chopping up sound files into smalll parts is
a problem. First, because it creates lots of files that can easily be
separated or misplaced. Second, because it is better to reference a
complete sound file to give context to any piece that you want to
quote. So using timecodes to annotate a whole file is the basic first
step and creates an index of the archival form of the media.
However, there are times when you do need to chop up a sound file.
For example, you may need to insert audio clips into an online
dictionary. If a speaker of the language has had the patience to read
all the headwords, then you can transcribe and time-align this
material using Transcriber, and then export the text using the 'Limsi
label' format.
The freely available program Audacity can import this file as
Audacity labels. Having opened the audio file and then imported the
labels you can select the 'Export multiple' option and Audacity will
chop up the file along the labelled timecodes, and will name each
file with the label. This means you will then have many named files,
ready to be referenced by your dictionary, and, if the labels are the
same as the headword then it should be easy enough to automate the
linking of the audio and text of the dictionary.
