class MusicFlamingoConfig(PreTrainedConfig):

    audio_bos_token_id (`int`, *optional*, defaults to 151670):
        The beginning-of-audio token index used to mark the start of audio spans.

        The end-of-audio token index used to mark the end of audio spans.

        Duration in seconds of one input mel frame (trained with hop_length 160 at sampling_rate 16000).

    Example:
