Abstract: The present technology relates to a signal processing apparatus, a signal processing method, and a program each enabling reproduction of images and sounds in a synchronized manner. A signal processing apparatus includes a reproduction control unit configured to control, on the basis of image data of an image associated with a sound based on multichannel audio data, reproduction of the image, and a synchronization signal generation unit configured to generate a synchronization signal for reproducing the sound synchronized with the image on the basis of the multichannel audio data, on the basis of audio data for reproducing the sound, the audio data being smaller in number of channels than the multichannel audio data. The present technology is applicable to an omnidirectional contents reproduction system.
