  text: Zero-shot classifiers based on Contrastive Language-Audio Pretraining (CLAP)
    models enable classification of given audio into classes defined at test time
    using text. These models are costly to run with respect to computation and memory
    requirements. In this work, we propose to build a specialized low-resource classifier
    for classes pre-defined using text, using a two-stage procedure consisting of
    zero-shot data set pruning and model compression. First, relevant in-domain data
    is selected from a source dataset using class label embeddings obtained from a
    pre-trained CLAP model. This data is then used to distill the audio encoder of
    a CLAP model. The proposed compression method produces compact audio encoders
    with slightly reduced accuracy. Note that neither labeled nor unlabeled in-domain
    audio data is required for its development. We verify by cross-dataset tests that
    the resulting classifiers are indeed specialized to their task.
