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?
