class XYTokenizerConfig(PretrainedConfig):
    r"""
    This is the configuration class to store the configuration of a [`XYTokenizerModel`]. It is used to instantiate a
    XY Tokenizer model according to the specified arguments, defining the model architecture.

    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
    documentation from [`PretrainedConfig`] for more information.

    Args:
        input_sample_rate (`int`, *optional*, defaults to 16000):
            The sampling rate of the input audio.
        output_sample_rate (`int`, *optional*, defaults to 16000):
            The sampling rate of the output audio.
        encoder_downsample_rate (`int`, *optional*, defaults to 1280):
            The total downsampling factor of the encoder part.
        decoder_upsample_rate (`int`, *optional*, defaults to 1920):
            The total upsampling factor of the decoder part.
        code_dim (`int`, *optional*, defaults to 1280):
            The dimension of the code embeddings.
        
        // ... (All other parameters from the original YAML/dict config would be listed here) ...
        // For brevity, we will define them with default values based on the provided code.
        
        Example:
        semantic_encoder_d_model (`int`, *optional*, defaults to 1280):
             Hidden dimension for the semantic encoder.
        num_quantizers (`int`, *optional*, defaults to 32):
            Number of residual quantizers.
        ...
