-This pipeline includes a main operator: [audio embedding](https://hub.towhee.io/towhee/audio-embedding-operator-template) (implemented as [towhee/clmr-magnatagatune](https://hub.towhee.io/towhee/clmr-magnatagatune)). The audio embedding operator encodes fixed-length clips of an audio data and finally output a set of vectors of the given audio.
