I created this due to someone on the forum asking about the format. You can download the encoder and decoder for MP3HD here: [HTML]http://mp3hd-toolkit.soft32.com/[/HTML]
Known bugs:
When telling dBpoweramp to write ID3 tags to the file, only the lossy portion of the MP3 is saved. Even with the
switch and writing tags using the
switch it still stripts out the lossless portion stored in the tag.
I wouldn't recommend anyone using this encoder as the correction data is in the ID3 tag, because mp3 doesn't allow frame sizes large enough. Therefore, your lossless collection could too easily be lost with a basic mass-tagging operation.
The lossless part of the codec is stored in ID3v2 tags.
The size of ID3v2 tags is limited to 256MB by specifications; as a result, the lossless part of an mp3hd file may not be over 256MB.
You have been warned!
On the flipside, you apparently get a true Fraunhofer MP3 encoder for normal MP3 if you tag files, so there’s that…
If you want to only encode to lossless, just use the cli encoder, uncheck Write Tags, place .mp3 only in the encoder.txt file, and the switches
.

-----------------------------------------------------------------------------
The mp3HD Format (Some Terminology)
-----------------------------------------------------------------------------
mp3HD is a new scalable format for high-quality lossless compression
of audio signals. It guarantees bit-exact reproduction of the
original PCM samples at state-of-the-art compression ratios. As for
all lossless compression formats, the compression ratio and resulting
data rate depends on the compressed content. As a rule of thumb, the
mp3HD codec can compress WAV files to about 30% to 60% of their
original size for typical audio content. Typically, smaller data
rates are needed to encode classical music or audio books, while Rock
and Pop music requires larger data rates.
mp3HD has been designed with the explicit target to be as compatible
as possible to the ubiquitous MP3 format. As a consequence, the mp3HD
format uses advanced compression algorithms and a special bit stream
format in order to be compatible to most of the available MP3 players.
Therefore mp3HD is both a lossless format for the reproduction of the
original PCM samples and a standard MP3 file that play's on your MP3
player.
The mp3HD Format supports tagging the files with meta data according
to ID3 Version 1.0, 1.1, 2.3 and 2.4. That is, you can use many
existing tools to add ID3 tags to your mp3HD content, and to manage
and organize your audio collection.
-----------------------------------------------------------------------------
mp3HD Command-Line Encoder
-----------------------------------------------------------------------------
This program encodes WAV audio files to mp3HD files. The WAV audio
files have to contain plain PCM samples in mono or stereo with a
resolution of 16 bit per sample. The sample rate is restricted to one
out of 32 kHz, 44.1 kHz, or 48 kHz.
It is in the nature of lossless audio compression that the resulting
bit rate is inherently defined by the audio content. Consequently,
the bit rate of the mp3HD file cannot be specified. However, the
target bit rate for the backwards-compatible MP3 bit stream already
has to be specified at the time of encoding the mp3HD file. You can
select both variable bit rate (VBR) mode at several qualities or
constant bit rate (CBR) mode for the resulting MP3 via the
command-line argument "-mode".
For CBR mode you can further define the data rate for the resulting
MP3 file. The range of possible bit rates is constrained as follows:
Stereo signals:
- sample rate of 32 kHz: 80000 - 320000 bit/s
- sample rate of 44.1 kHz: 96000 - 320000 bit/s
- sample rate of 48 kHz: 112000 - 320000 bit/s
Mono signals:
- sample rate of 32 kHz: 40000 - 320000 bit/s
- sample rate of 44.1 kHz: 56000 - 320000 bit/s
- sample rate of 48 kHz: 56000 - 320000 bit/s
To add existing ID3 meta data to the mp3HD file use the command-line
arguments "-id3in" to pass an existing ID3 (Ver. 2.3 or 2.4) meta data
file to the mp3HD encoder. For example, the file can be an existing mp3
file that includes the desired ID3 tag information.
Alternatively, you can use the following command-line arguments to set
the ID3 meta data directly:
-Title "[title string]"
-Artist "[artist string]"
-Album "[album string]"
-Track "[track number]"
-Length "[length in ms]"
-Year "[year string]"
-Genre "[content type]"
-Encoder "[encoded by ..]"
-Encoder_Settings "[encoder name and settings]"
-pic "[jpegFile]"
The "-id3in" command-line argument can't be used in combination
with the other ID3 command-line arguments.
To call the mp3HD command-line encoder simply open a command prompt
and enter "mp3hdEncoder". If called without arguments, the encoder
outputs a list of possible command-line arguments and encoding
options.
-----------------------------------------------------------------------------
mp3HD Command-Line Decoder
-----------------------------------------------------------------------------
This program decodes mp3 and mp3HD files to WAV audio files. The output
files contain bit-exactly the same PCM samples as the originally encoded
WAV files.
Note that the mp3HD decoder cannot reconstruct any side information,
i.e. additional chunks besides the actual audio data, that may have
been contained in the original WAV file. Therefore, you may observe
differences if you compare the decoded WAV file with the original WAV
file on the file level.
To call the command-line decoder simply open a command prompt and
enter "mp3hdDecoder". If called without arguments, the decoder
outputs a list of possible command-line arguments and decoding
options.
-----------------------------------------------------------------------------
mp3HD Winamp Decoder
-----------------------------------------------------------------------------
If you have a Winamp player installed, the mp3HD format can be added
to the audio formats supported by the player. By default, the mp3HD
Winamp Decoder plugin decodes mp3HD files in mp3HD quality, i.e. the
high-quality original PCM samples are played.
You may configure the plugin to play mp3 quality instead of mp3HD quality
by default. In addition, you can activate in the settings dialog to
display a window in which you can switch between mp3 quality and mp3HD
quality in real time while decoding an mp3HD file.
We recommend to use Winamp version 5.5 or above. The new version of
the Winamp player can be downloaded at http://www.winamp.com.
To install the Winamp decoder plug-in copy the "in_mp3hd.dll" file to
your local Winamp plug-in folder. Typically, the directory of the Winamp
plug-in folder is "C:\Program Files\Winamp\plugin".

FAQ
-----------------------------------------------------------------------------
** What are PCM samples?
The acronym PCM stands for pulse code modulation. In most digital
workflows, PCM samples describe the raw digital audio signals
either right after conversion from the analog domain or before
conversion to the analog domain.
PCM samples are not compressed like e.g. MP3 files. Therefore,
they offer in principle the best possible sound quality for a given
sample rate and resolution. As an example, a CD stores audio as
PCM samples with a rate of 44100 samples per second (and channel)
and a resolution of 16 bit per sample. This gives a bit rate of
1411.2 kbit/s.
** Can I use the mp3HD Codec to rip my audio CDs?
To rip mp3HD files from your audio CDs you need an audio CD
grabber tool with external Encoder support. For example you can use
the Exact Audio Copy CD grabber. The current version of Exact Audio
Copy can be downloaded at
http://www.exactaudiocopy.de/en/index.php/resources/download/.
You can include the mp3HD encoder into the Exact Audio Copy grabber
by performing the following steps:
- Open the "Compression options" from the "EAC" menu
- Go to the "External Compression" tab
- Enable the "Use external program for compression" option
- Set "Parameter passing scheme" to "User Defined Encoder"
- Write ".mp3" into the "Use file extension" field
- Type the link to your mp3hdEncoder.exe file into the
"Program, including Path, used for compression" field
- Insert the following text into the Additional command-line option field:
-if %s -of %d -br %r000 -Artist "%a" -Album "%g" -Title "%t" -Year "%y"
-Track "%n" -Genre "%m"
- Select the desired bit rate in the "Bit rate" field.
- Uncheck the "Add ID3 tag" option

The mp3HD Format (Some Terminology)
-----------------------------------------------------------------------------
mp3HD is a new scalable format for high-quality lossless compression
of audio signals. It guarantees bit-exact reproduction of the
original PCM samples at state-of-the-art compression ratios. As for
all lossless compression formats, the compression ratio and resulting
data rate depends on the compressed content. As a rule of thumb, the
mp3HD codec can compress WAV files to about 30% to 60% of their
original size for typical audio content. Typically, smaller data
rates are needed to encode classical music or audio books, while Rock
and Pop music requires larger data rates.
mp3HD has been designed with the explicit target to be as compatible
as possible to the ubiquitous MP3 format. As a consequence, the mp3HD
format uses advanced compression algorithms and a special bit stream
format in order to be compatible to most of the available MP3 players.
Therefore mp3HD is both a lossless format for the reproduction of the
original PCM samples and a standard MP3 file that play's on your MP3
player.
The mp3HD Format supports tagging the files with meta data according
to ID3 Version 1.0, 1.1, 2.3 and 2.4. That is, you can use many
existing tools to add ID3 tags to your mp3HD content, and to manage
and organize your audio collection.
-----------------------------------------------------------------------------
mp3HD Command-Line Encoder
-----------------------------------------------------------------------------
This program encodes WAV audio files to mp3HD files. The WAV audio
files have to contain plain PCM samples in mono or stereo with a
resolution of 16 bit per sample. The sample rate is restricted to one
out of 32 kHz, 44.1 kHz, or 48 kHz.
It is in the nature of lossless audio compression that the resulting
bit rate is inherently defined by the audio content. Consequently,
the bit rate of the mp3HD file cannot be specified. However, the
target bit rate for the backwards-compatible MP3 bit stream already
has to be specified at the time of encoding the mp3HD file. You can
select both variable bit rate (VBR) mode at several qualities or
constant bit rate (CBR) mode for the resulting MP3 via the
command-line argument "-mode".
For CBR mode you can further define the data rate for the resulting
MP3 file. The range of possible bit rates is constrained as follows:
Stereo signals:
- sample rate of 32 kHz: 80000 - 320000 bit/s
- sample rate of 44.1 kHz: 96000 - 320000 bit/s
- sample rate of 48 kHz: 112000 - 320000 bit/s
Mono signals:
- sample rate of 32 kHz: 40000 - 320000 bit/s
- sample rate of 44.1 kHz: 56000 - 320000 bit/s
- sample rate of 48 kHz: 56000 - 320000 bit/s
To add existing ID3 meta data to the mp3HD file use the command-line
arguments "-id3in" to pass an existing ID3 (Ver. 2.3 or 2.4) meta data
file to the mp3HD encoder. For example, the file can be an existing mp3
file that includes the desired ID3 tag information.
Alternatively, you can use the following command-line arguments to set
the ID3 meta data directly:
-Title "[title string]"
-Artist "[artist string]"
-Album "[album string]"
-Track "[track number]"
-Length "[length in ms]"
-Year "[year string]"
-Genre "[content type]"
-Encoder "[encoded by ..]"
-Encoder_Settings "[encoder name and settings]"
-pic "[jpegFile]"
The "-id3in" command-line argument can't be used in combination
with the other ID3 command-line arguments.
To call the mp3HD command-line encoder simply open a command prompt
and enter "mp3hdEncoder". If called without arguments, the encoder
outputs a list of possible command-line arguments and encoding
options.
-----------------------------------------------------------------------------
mp3HD Command-Line Decoder
-----------------------------------------------------------------------------
This program decodes mp3 and mp3HD files to WAV audio files. The output
files contain bit-exactly the same PCM samples as the originally encoded
WAV files.
Note that the mp3HD decoder cannot reconstruct any side information,
i.e. additional chunks besides the actual audio data, that may have
been contained in the original WAV file. Therefore, you may observe
differences if you compare the decoded WAV file with the original WAV
file on the file level.
To call the command-line decoder simply open a command prompt and
enter "mp3hdDecoder". If called without arguments, the decoder
outputs a list of possible command-line arguments and decoding
options.
-----------------------------------------------------------------------------
mp3HD Winamp Decoder
-----------------------------------------------------------------------------
If you have a Winamp player installed, the mp3HD format can be added
to the audio formats supported by the player. By default, the mp3HD
Winamp Decoder plugin decodes mp3HD files in mp3HD quality, i.e. the
high-quality original PCM samples are played.
You may configure the plugin to play mp3 quality instead of mp3HD quality
by default. In addition, you can activate in the settings dialog to
display a window in which you can switch between mp3 quality and mp3HD
quality in real time while decoding an mp3HD file.
We recommend to use Winamp version 5.5 or above. The new version of
the Winamp player can be downloaded at http://www.winamp.com.
To install the Winamp decoder plug-in copy the "in_mp3hd.dll" file to
your local Winamp plug-in folder. Typically, the directory of the Winamp
plug-in folder is "C:\Program Files\Winamp\plugin".

FAQ
-----------------------------------------------------------------------------
** What are PCM samples?
The acronym PCM stands for pulse code modulation. In most digital
workflows, PCM samples describe the raw digital audio signals
either right after conversion from the analog domain or before
conversion to the analog domain.
PCM samples are not compressed like e.g. MP3 files. Therefore,
they offer in principle the best possible sound quality for a given
sample rate and resolution. As an example, a CD stores audio as
PCM samples with a rate of 44100 samples per second (and channel)
and a resolution of 16 bit per sample. This gives a bit rate of
1411.2 kbit/s.
** Can I use the mp3HD Codec to rip my audio CDs?
To rip mp3HD files from your audio CDs you need an audio CD
grabber tool with external Encoder support. For example you can use
the Exact Audio Copy CD grabber. The current version of Exact Audio
Copy can be downloaded at
http://www.exactaudiocopy.de/en/index.php/resources/download/.
You can include the mp3HD encoder into the Exact Audio Copy grabber
by performing the following steps:
- Open the "Compression options" from the "EAC" menu
- Go to the "External Compression" tab
- Enable the "Use external program for compression" option
- Set "Parameter passing scheme" to "User Defined Encoder"
- Write ".mp3" into the "Use file extension" field
- Type the link to your mp3hdEncoder.exe file into the
"Program, including Path, used for compression" field
- Insert the following text into the Additional command-line option field:
-if %s -of %d -br %r000 -Artist "%a" -Album "%g" -Title "%t" -Year "%y"
-Track "%n" -Genre "%m"
- Select the desired bit rate in the "Bit rate" field.
- Uncheck the "Add ID3 tag" option
