mp3 images on in-dash radio
I processed several lecture series (analogue voice streams) as
follows:
(1) record each stream as a WAV file on a TASCAM digital recorder
(2) load each WAV file into "Audacity" as a project, for editing and
for manual insertion of a number of filename labels, to label sessions
within each lecture series
(3) use the "Audacity" FILE -> EXPORT MULTIPLE function to split each
project into WAV files corresponding to the manually-inserted labels,
with each session in a separate file
(4) use "lame" to encode each of the WAV files as MP3
(5) use "id3tool" to create for each MP3 file a tag showing TRACK,
TITLE, ARTIST, ALBUM, YEAR. (These fields have to do with the lecture
series, lecture topic, and session number; they are not artist name
and album and song titles in the usual sense.)
(6) copy the MP3 files into folders of a directory structure, sorting
them by lecture series
(7) use "puddletag" to create a playlist for each folder (lecture
series), to play sessions in proper order
(8) copy the directory structure to a USB flash memory stick, for
playback over the in-dash radio of an automobile.
PROBLEM: For some of the sessions, the LCD display of the in-dash
radio displays an image. The image is not related to any of the
series of lectures. Moreover, some of the images are objectionable.
Some in-dash radios make display of images optional.
I have been unable to determine the source of the images. I have
found no clues from searching on the Web.
= Is it possible that an image is embedded in the MP3 file which I
have created? Or can there be a URL to an image in the label which I
have created? If so, at what stage of the processing was the image or
link introduced? How can I remove them?
= Doe the image originate in the in-dash radio? If so, where does it
reside, and how and why is it associated with my files?
