[`Pop2PianoProcessor`] offers all the functionalities of [`Pop2PianoFeatureExtractor`] and [`Pop2PianoTokenizer`]. See the docstring of [`~Pop2PianoProcessor.__call__`] and [`~Pop2PianoProcessor.decode`] for more information. Args: feature_extractor (`Pop2PianoFeatureExtractor`): An instance of [`Pop2PianoFeatureExtractor`]. The feature extractor is a required input. tokenizer (`Pop2PianoTokenizer`): An instance of ['Pop2PianoTokenizer`]. The tokenizer is a required input. feature_extractor tokenizerPop2PianoFeatureExtractorPop2PianoTokenizercst||dSN)super__init__)selfrr __class__o/home/ubuntu/veenaModal/venv/lib/python3.10/site-packages/transformers/models/pop2piano/processing_pop2piano.pyr1szPop2PianoProcessor.__init__NTFaudio sampling_ratesteps_per_beatresamplenotespadding truncation max_lengthpad_to_multiple_ofverbosereturnc  Ks|dur|dur|durtd|dur%|dur%|jd||||d| } |dur8|jd||||| | d| } |dur>| S|dusF|durH| S| d| d<| S)a" This method uses [`Pop2PianoFeatureExtractor.__call__`] method to prepare log-mel-spectrograms for the model, and [`Pop2PianoTokenizer.__call__`] to prepare token_ids from notes.
