SMPE 16-mm. Test-Films

A brief description of the SMPE 16-mm. sound and visual test-films. The visual test-film is an optical reduction of the 35-mm. visual test-film; and the 16-mm. sound test-film is an optical reduction of a special 35-mm. recording, pre-corrected so that the selected frequencies (50 to 6000 cycles) will be reproduced at constant level by an ideal reproducer.
