    public class WaveFeatureGenerator
extends adams.flow.transformer.AbstractTransformer
implements adams.flow.transformer.FeatureGenerator<AbstractWaveFeatureGenerator>
    Applies an Wave feature generator to the incoming image and outputs the generated features.

    Input/output:
    - accepts:
       adams.data.audio.WaveContainer
    - generates:
       adams.data.spreadsheet.Row


    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
 
    -name <java.lang.String> (property: name)
    The name of the actor.
    default: WaveFeatureGenerator
 
    -annotation <adams.core.base.BaseAnnotation> (property: annotations)
    The annotations to attach to this actor.
    default:
 
    -skip <boolean> (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
    default: false
 
    -stop-flow-on-error <boolean> (property: stopFlowOnError)
    If set to true, the flow execution at this level gets stopped in case this
    actor encounters an error; the error gets propagated; useful for critical
    actors.
    default: false
 
    -silent <boolean> (property: silent)
    If enabled, then no errors are output in the console; Note: the enclosing
    actor handler must have this enabled as well.
    default: false
 
    -algorithm <adams.data.audiofeaturegenerator.wave.AbstractWaveFeatureGenerator> (property: algorithm)
    The feature generation algorithm to use.
    default: adams.data.audiofeaturegenerator.wave.Fingerprint -converter \"adams.data.featureconverter.SpreadSheet -data-row-type adams.data.spreadsheet.DenseDataRow -spreadsheet-type adams.data.spreadsheet.DefaultSpreadSheet\"
