class AudioAssembler extends Transformer with DefaultParamsWritable with HasOutputAnnotatorType with HasOutputAnnotationCol

Prepares audio read by Spark into a format that is processable by Spark NLP. This component is needed to process audio.

Input col is a single record that contains the raw content and metadata of the file.

Example

import com.johnsnowlabs.nlp.AudioAssembler
import org.apache.spark.ml.Pipeline

val audioAssembler = new AudioAssembler()
  .setInputCol("audio")
  .setOutputCol("audio_assembler")

val pipeline = new Pipeline().setStages(Array(audioAssembler))
val pipelineDF = pipeline.fit(imageDF).transform(wavDf)
pipelineDF.printSchema()
