This will output `partial` overlapping chunks starting from `stream_chunk_s` (if it is defined) until `chunk_length_s` is reached. It will make use of striding to avoid errors on the "sides" of the various chunks. Arguments: sampling_rate (`int`): The sampling_rate to use when reading the data from the microphone. Try using the model's sampling_rate to avoid resampling later. chunk_length_s (`float` or `int`): The length of the maximum chunk of audio to be sent returned. This includes the eventual striding. stream_chunk_s (`float` or `int`) The length of the minimal temporary audio to be returned. stride_length_s (`float` or `int` or `(float, float)`, *optional*, defaults to `None`) The length of the striding to be used. Stride is used to provide context to a model on the (left, right) of an audio sample but without using that part to actually make the prediction. Setting this does not change the length of the chunk. format_for_conversion (`str`, defalts to `f32le`) The name of the format of the audio samples to be returned by ffmpeg. The standard is `f32le`, `s16le` could also be used. Return: A generator yielding dictionaries of the following form `{"sampling_rate": int, "raw": np.array(), "partial" bool}` With optionnally a `"stride" (int, int)` key if `stride_length_s` is defined. `stride` and `raw` are all expressed in `samples`, and `partial` is a boolean saying if the current yield item is a whole chunk, or a partial temporary result to be later replaced by another larger chunk.
