NAME
       atracdenc - encode to or	decode from ATRAC format

SYNOPSIS
       atracdenc  [options]  {-e  <codec> | -encode=<codec> | -d | -decode} -i
       <in> -o <out>

DESCRIPTION
       atracdenc is an audio converter that can	encode into ATRAC1  or	ATRAC3
       compatible format and decode from ATRAC1.

       For  ATRAC1 (also known as ATRAC	SP on MiniDisk devices)	AEA audio con-
       tainer is used. Only one	bitrate	(292 kbit/s) is	specified.

       For ATRCA3 (also	known as ATRAC LP on MiniDisk devices) OMA,  AT3(riff)
       and  RealMedia  container is supported. In the case of OMA and AT3 con-
       tainer, compatible bitrates are 66150 (LP4), 104738  and	 132300	 (LP2)
       bits/s.	The RealMedia container	supports 66150,	93713, 104738, 132300,
       146081, 176400, 264600 and 352800 bits/s.

OPTIONS
       -h     Display help.

       -i     Path  to	the  input file. In case of encoding it	should be WAV,
	      AIFF or SND 44100	Khz 16 bit PCM file. Use - to read from	stdin.

       -o     Path to the output file. The container format is chosen automat-
	      icaly according to the file extension.

       -e <codec>
	      Encode mode. <codec> is a	codec name  must  be  one  of  atrac1,
	      atrac3, atrac3_lp2, atrac3_lp4.

       --encode=<codec>
	      Alias for	-e.

       -d     Decode mode. Only	ATRAC1 is supported.

       --decode
	      Alias for	-d.

       --bitrate
	      Specify using bitrate (kbit/s). It make sense only for ATRAC3.

       ADVANCED	OPTIONS

       --bfuidxconst
	      Set constant amount of used BFU (ATRAC1, ATRAC3).

       --bfuidxfast
	      Enable fast search of BFU	amount (ATRAC1).

       --notransient[=mask]
	      Disable  transient  detection  and  use  an optional mask	to set
	      bands with a forced short	MDCT window.

       EXAMPLES

       ATRAC1 compatible encoding

	      atracdenc	-e atrac1 -i in.wav -o out.aea

       ATRAC3 LP2 compatible encoding

	      atracdenc	-e atrac3 -i in.wav -o out.oma

       ATRAC3 LP4 compatible encoding (low quality)

	      atracdenc	-e atrac3_lp4 -i in.wav	-o out.oma

       ATRAC3 +	RealAudio container + max supported bitrate

	      atracdenc	-e atrac3 --bitrate=344	-i in.wav -o out.rm
