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.
CONCLUSION
Although stereophony is attaining a respectable age, much more information must be obtained before it ran be said to rest on a foundation of quantitative relationships. It is hoped that this
summary of present knowledge will stimulate the acquisition of this information, and in the interim will srrvr as a useful guide to those who musi make recordings without waiting for complete theoretical understanding.
