We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

Stripe Recording The great advantage of magnetic stripe is that timing problems are eliminated. You have only to speak the commentary in step with the picture and it can never be reproduced out of synchronism. The recording is carried on the film itself and speed variations affect the picture and sound to the same extent. Projector Noise Although this single-system recording overcomes several serious problems, it introduces new ones. The most troublesome is projector noise. Magnetic stripe projectors are designed to run as quietly as possible and are often built into a blimp or box which deadens the sound. Nevertheless the reciprocating parts in a projector inevitably make more noise than a smoothly rotating tape recorder and since the stripe projector must be running during recording, it is difficult to produce a commentary which has no background of projector noise. This can be minimised in various ways. 1. Speaking louder and turning down the volume. 2. Speaking closer to the microphone and turning down the volume. 3. Using a directional microphone. 4. Increasing the distance from projector to microphone. 5. Muffling the projector noise. 6. Placing the projector and commentator in separate rooms. None of these remedies is as simple as it appears and you may have to use a combination of them all. Let us consider them separately. 97
