SoundStorm is an audio generation technology developed by Google Research that significantly reduces the time needed for audio synthesis by generating audio tokens in parallel.

The significance of SoundStorm lies in its ability to tackle the slow inference speed issues faced by traditional autoregressive audio generation models when processing long sequences, thereby enhancing both the efficiency and quality of audio generation.
