Build Requirements: | QuickTime 5 |
Runtime Requirements: | Carbon |
This sample creates and manages a dialog window containing a graphic equalizer display, similar to the one in the "LCD panel" in QuickTime Player. Really there are just two key functions that you use to make this happen, MediaSetSoundEqualizerBands and MediaGetSoundEqualizerBandLevels. Important Note: While this sample still functions with QuickTime 7, the APIs being demonstrated; MediaSetSoundEqualizerBands and MediaGetSoundEqualizerBandLevel are no longer preferred. Developers should use the new Movie level APIs SetMovieAudioFrequencyMeteringNumBands and GetMovieAudioFrequencyLevels. See the Audio Playback Enhancements section of the QuickTime 7 Update Guide for more information.
