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.

One method of mixing commentary and music on tape is twin-track recording. The commentary is recorded first (top left) on one side of the tape. Later (top right) it is played back, mixed with music in the amplifier and re-recorded on the other side of the tape. On the completed recording (bottom), the side carrying the commentary alone can be erased later.
While you are doing this, the combined speech and music are being recorded by the normal record/playback head onto the unused standard side of the tape. So at the end of the process, you have a combined recording in the normal position while still retaining the preliminary recording of commentary alone on the "wrong" half. If the combination of speech and music is not completely satisfactory, you can repeat the process until it is. When you are satisfied with the result, you can reverse the reels to erase the "wrong" half and use it in the normal manner for some other purpose.
This method has the advantage of allowing you to perfect your commentary independently of the music. Any mistakes can be erased and corrected in the usual way without any complications. The mere knowledge that this is so, often serves to put the commentator at his ease and so contributes to a good performance which may not need revision.
To many enthusiasts, the electrical aspects will present a difficulty. They are a simple matter to anyone familiar with radio sets, so call in the assistance of a radio engineer if necessary. Tape recorders vary considerably in detail: some include the necessary provision for mixing inputs, others do not. On some you can listen to what you are recording, but often you cannot.
