Fritts filed a patent claiming the idea. In 1923 a patent was filed by E. E. Ries, for a variable density soundtrack recording, which was submitted to the SMPE (now <a href="/wiki/Society_of_Motion_Picture_and_Television_Engineers" title="Society of Motion Picture and Television Engineers">SMPTE</a>), which used the mercury vapor lamp as a modulating device to create a variable-density soundtrack.

A two-channel audio signal is recorded as a pair of lines running parallel with the film's direction of travel through the projector's screen. The lines change area (grow broader or narrower) depending on the magnitude of the signal. The projector shines light from a small lamp, called an <a href="/wiki/Exciter_bulb" class="mw-redirect" title="Exciter bulb">exciter</a>, through a perpendicular slit onto the film. The image on the small slice of exposed track modulates the intensity of the light, which is collected by a photosensitive element: a photocell, a <a href="/wiki/Photodiode" title="Photodiode">photodiode</a> or <a href="/wiki/Charge-coupled_device" title="Charge-coupled device">CCD</a>. </p><p>In the early years of the 21st century distributors changed to using cyan dye optical soundtracks on color stocks, eliminating the need for a separate and difficult to control black-and-white emulsion on the soundtrack portion of the film. Because traditional incandescent exciter lamps produce copious amounts of infra-red light, and cyan tracks do not absorb infra-red light, this change required theaters to replace the incandescent exciter lamp with a complementary colored red <a href="/wiki/Light-emitting_diode" title="Light-emitting diode">LED</a> or laser. These LED or laser exciters are backwards-compatible with older tracks. </p><p>Earlier processes, used on <a href="/wiki/70_mm_film" title="70 mm film">70 mm film</a> prints and special presentations of <a href="/wiki/35mm_movie_film" class="mw-redirect" title="35mm movie film">35 mm film</a> prints, recorded sound magnetically on <a href="/wiki/Iron(III)_oxide" title="Iron(III) oxide">ferric oxide</a> tracks bonded to the film print, outside the sprocket holes. 16 mm and Super 8 formats sometimes used a similar magnetic track on the camera film, bonded to one side of the film on which the sprocket holes had not been punched ("single perforated") for the purpose. Film of this form is no longer manufactured, but single-perforated film without the magnetic track (allowing an optical sound track) or, in the case of 16 mm, utilising the soundtrack area for a wider picture (Super 16 format) is readily available. </p> <div class="mw-heading mw-heading2"><h2 id="Digital_sound-on-film_formats">Digital sound-on-film formats</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Sound-on-film&action=edit&section=3" title="Edit section: Digital sound-on-film formats"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Three different digital soundtrack systems for 35 mm cinema release prints were introduced during the 1990s.
