        this.audio_values = audio_values;
    }
Encodes the input audio waveform into discrete codes.
@param {Object} inputs Model inputs
@param {Tensor} [inputs.input_values] Float values of the input audio waveform, of shape `(batch_size, channels, sequence_length)`).
@returns {Promise<MimiEncoderOutput>} The output tensor of shape `(batch_size, num_codebooks, sequence_length)`.
