How this example was made
The soundtrack is an original sequence of synthesized tones generated by the example build script. Captions and speech recognition are disabled.
Use a visualizer when you want to preserve an instrumental soundtrack without captions. Spectrum bars react to the sound; they do not represent lyrics or detected instruments.
Rendering times are measured on the build computer for these short samples. They exclude upload, waiting in the queue and, unless stated separately, transcription. They are not a server speed or accuracy guarantee.
