Detailed Description

Encoder producing SpectMorph parametric data from sample data.

The encoder needs to perform a number of analysis steps to get from the input signal to a parametric representation (which is built in audio_blocks). At the moment, this process needs to be controlled by the caller, but a simpler interface should be added.

Constructor & Destructor Documentation

◆ Encoder()

Encoder::Encoder ( const EncoderParams & enc_params )

Constructor which initializes the Encoders parameters.

Member Function Documentation

◆ encode()

bool Encoder::encode	(	const WavData &	wav_data,
		int	channel,
		int	optimization_level,
		bool	attack,
		bool	track_sines
	)

This function calls all steps necessary for encoding in the right order.

Parameters

dhandle	a data handle containing the signal to be encoded
optimization_level	determines if fast (0), medium (1), or very slow (2) algorithm is used
attack	whether to find the optimal attack parameters

◆ save()

Error Encoder::save ( const std::string & filename )

This function saves the data produced by the encoder to a SpectMorph file.

◆ save_as_audio()

Audio * Encoder::save_as_audio ( )

This function saves the data produced by the encoder, returning a newly allocated Audio object (caller must free this).
