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.
Music and Effects
The recording studios can intersperse your commentary with music and sound effects if desired. This increases the cost of the recording by about one quarter. Here again, you can choose the type of music and sound effects to be added. Alternatively, the script-writer will do it for you.
Practically speaking, there is no limit to the sound effects at your disposal. The studios can usually find the effect you need in their comprehensive library. But if they cannot, they will be able to fake it quite readily.
With music things are not so simple. Copyright restrictions may prevent the studios from re-recording any record which strikes your fancy. So usually you must content yourself with indicating the kind of music you want — piano, dance, concert, symphony and so on.
Master Recordings
As a protection against accidents, the commentary is usually recorded first on magnetic tape. When the recording is satisfactory, it is re-recorded on to the disc or film, whichever you are using. In the case of film, the magnetic recording is kept at least until the film is developed. Then if the optical recording is not satisfactory, a second copy can be made from the tape.
Once you have got your disc or optical recording, the master recording on tape may be erased and the tape used for another job. However, the studios will usually retain the master for a small extra charge. Then if later on you want further copies — to replace worn discs, for example — you can get them made for a fraction of the original cost.
In the case of an optical sound track, you may not need to preserve a magnetic or disc master after you have got a satisfactory print. The optical recording is often made first on to a separate film. Later it is printed, with the picture, on to a single film to provide a married print. You can then keep the original optical recording as a master.
