Comment (by thilo.borgmann):

 I got no error message from the reference decoders, too.
 However, one just produced a 0-size file and the other just put some wav
 header bytes onto disk... please have a look at the actual files created.

 the file decodes correctly (afaict - no error messages) with:

 {{{
 C:\>C:\mp4alsRM23win\mp4alsRM23.exe -h

 mp4alsRM23 - MPEG-4 Audio Lossless Coding (ALS), Reference Model Codec
   Version 23 for Win32
   (c) 2003-2008 Tilman Liebchen, TU Berlin / LG Electronics
 E-mail: liebc...@nue.tu-berlin.de
   Portions by Yuriy A. Reznik, RealNetworks, Inc.
 E-mail: yrez...@real.com
   Portions by Koichi Sugiura, NTT Advanced Technology corporation
 E-mail: koichi.sugi...@ntt-at.co.jp
   Portions by Takehiro Moriya, Noboru Harada and Yutaka Kamamoto, NTT
 E-mail: {moriya.takehiro,harada.noboru,kamamoto.yutaka}@lab.ntt.co.jp

 Usage: mp4alsRM23 [options] infile [outfile]

   In compression mode, infile must be a PCM file (wav, aif, or raw format)
   or a 32-bit floating point file (normalized, wav format type 3).
   Mono, stereo, and multichannel files with up to 65536 channels and up to
   32-bit resolution are supported at any sampling frequency.
   In decompression mode (-x), infile is the compressed file (.als or
 .mp4).
   If outfile is not specified, the name of the output file will be
 generated
   by replacing the extension of the input file (wav <-> als).
   If outfile is '-', the output will be written to stdout. If infile is
 '-',
   the input will be read from stdin, and outfile has to be specified.

 General Options:
   -c  : Check accuracy by decoding the whole file after encoding.
   -d  : Delete input file after completion.
   -h  : Help (this message)
   -v  : Verbose mode (file info, processing time)
   -x  : Extract (all options except -v and -MP4 are ignored)
 Encoding Options:
   -7  : Set parameters for optimum compression (except LTP, MCC, RLSLMS)
   -a  : Adaptive prediction order
   -b  : Use BGMC codes for prediction residual (default: use Rice codes)
   -e  : Exclude CRC calculation
   -f# : ACF/MLZ mode: # = 0-7, -f6/-f7 requires ACF gain value
   -g# : Block switching level: 0 = off (default), 5 = maximum
   -i  : Independent stereo coding (turn off joint stereo coding)
   -l  : Check for empty LSBs (e.g. 20-bit files)
   -m# : Rearrange channel configuration (example: -m1,2,4,5,3)
   -n# : Frame length: 0 = auto (default), max = 65536
   -o# : Prediction order (default = 10), max = 1023
   -p  : Use long-term prediction
   -r# : Random access (multiples of 0.1 sec), -1 = each frame, 0 = off
 (default)

   -s# : Multi-channel correlation (#=1-65536, jointly code every #
 channels)
 # must be a divisor of number of channels, otherwise -s is ignored
   -sp#: Enforce ALS Simple Profile Level # (currently only #=1 is defined)
   -t# : Two methods mode (Joint Stereo and Multi-channel correlation)
 # must be a divisor of number of channels
   -u# : Random access info location, 0 = frames (default), 1 = header, 2 =
 none
   -z# : RLSLMS mode (default = 0: no RLSLMS mode,  1-quick, 2-medium
 3-best )
 MP4 File Format Support:
   -MP4: Use MP4 file format for compressed file (default if extension is
 .mp4)
   -OAFI:Force to embed meta box with oafi record
   -npi: Do not indicate the conformant profiles in the MP4 file
 Audio file support:
   -R  : Raw audio file (use -C, -W, -F and -M to specify format)
   -S# : Sample type: 0 = integer (default), 1 = float
   -C# : Number of Channels (default = 2)
   -W# : Word length in bits per sample (default = 16)
   -F# : Sampling frequency in Hz (default = 44100)
   -M  : 'MSByte first' byte order (otherwise 'LSByte first')
   -H# : Header size in bytes (default = 0)
   -T# : Trailer size in bytes (default = 0)
   -I  : Show info only, no (de)compression (add -x for compressed files)

 Examples:
   mp4alsRM23 -v sound.wav
   mp4alsRM23 -n1024 -i -o20 sound.wav
   mp4alsRM23 - sound.als < sound.wav
   mp4alsRM23 -x sound.als
   mp4alsRM23 -x sound.als - > sound.wav
   mp4alsRM23 -I -x sound.als

Comment (by thilo.borgmann):

 For me, both RM22rev2 and RM23 of the reference software fail to decode
 this properly. Have you tested decoding with these?
