NAME    [Toc]    [Back]

     dmFS1016DecoderGetParams -	get FS1016 decoder parameter values

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/dm_audioutil.h>
     #include <dmedia/dm_audio.h>
     #include <dmedia/dm_params.h>

     DMstatus dmFS1016DecoderGetParams(DMFS1016decoder handle,
				   DMparams *params)

PARAMETER    [Toc]    [Back]

     handle   DMFS1016decoder structure, created by
	      dmFS1016DecoderCreate(3dm).


     params   List of parameters for query.

RETURNED VALUE    [Toc]    [Back]

     Returns DM_SUCCESS	or DM_FAILURE.

DESCRIPTION    [Toc]    [Back]

     dmFS1016DecoderGetParams(3dm) gets	state of FS1016	decoder	with params.


     The set of	parameters of params for query are, defined in
     dmedia/dm_audioutil.h and dmedia/dm_audio.h:

     DM_AUDIO_BITRATE    [Toc]    [Back]
     DM_AUDIO_CODEC_MAX_BYTES_PER_BLOCK
     DM_AUDIO_CODEC_FRAMES_PER_BLOCK
     DM_AUDIO_CODEC_FILTER_DELAY
     DM_FS1016_POSTFILTERING_FLAG
     DM_FS1016_HIGHPASS_FLAG


     The value for DM_AUDIO_BITRATE can	be

     DM_FS1016_4800_BITS    [Toc]    [Back]
     DM_FS1016_7200_BITS
     DM_FS1016_9600_BITS


     The value for DM_FS1016_POSTFILTERING_FLAG	can be

     DM_FS1016_POSTFILTERING_YES    [Toc]    [Back]
     DM_FS1016_POSTFILTERING_NO

     The value for DM_FS1016_HIGHPASS_FLAG can be

     DM_FS1016_HIGHPASS_YES    [Toc]    [Back]
     DM_FS1016_HIGHPASS_NO


     The above values select a decoder with desired bitrate and	with or
     without postfiltering and highpass	filtering.  Cautious application of
     postfiltering at the decoder's output is recommended.  The	human ear's
     masking properties	are exploited to trade off speech distortion vs.
     quantizing	noise.	In tandem coding scenarios, only one stage of
     postfiltering is recommended and multiple stages should be	avoided.  The
     bitrate and decode	mode are set by	a call to
     dmFS1016DecoderSetParams(3dm). Without calling
     dmFS1016DecoderSetParams(3dm), decoder sets defaults to 4800 bits/s,
     DM_FS1016_POSTFILTERING_YES, and DM_FS1016_HIGHPASS_NO.
