Can you comment (either generally or wrt your product) on specificity/generality/constraints when searching for audio? The image-based examples are intuitive, but what features can one search for in audio? i.e. Can it detect a specific singer's voice, or an instrument or effect? Only more general features like genre, tempo, etc? I assume it's some combination, but it's not clear to me what this type of neural search is "good at".
