+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+[the GitHub Issues Tab](https://github.com/iluvcapra/wavinfo/issues).
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+

 # wavinfo
 
+The `wavinfo` package allows you to probe WAVE and [RF64/WAVE files][eburf64] 
+and extract extended metadata. `wavinfo` has an emphasis on film, video and 
+professional music production but can read many other kinds.
 
-The `wavinfo` package allows you to probe WAVE files and extract extended metadata, with an emphasis on 
-production metadata. 
+If you are trying to read a particular kind of metadata from a WAV file and
+it is not supported, please submit an issue!
+
+
+## Metadata Support
 
 `wavinfo` reads:
 
-* __Broadcast-WAVE__ metadata, compliant with [EBU Tech 3285v2 (2011)][ebu], including embedded program 
-  loudness and coding history, if extant. This also includes the [SMPTE 330M __UMID__][smpte_330m2011] 
-  Unique Materials Identifier.
-* [__iXML__ production recorder metadata][ixml], including project, scene, and take tags, recorder notes 
-  and file family information.
-* Most of the common __RIFF INFO__ metadata fields.
-* The __wav format__ is also parsed, so you can access the basic sample rate and channel count 
-  information.
-
-In progress:
-* iXML `STEINBERG` sound library attributes.
-* Pro Tools __embedded regions__.

-[ixml]:http://www.ixml.info
+* All defined [Broadcast-WAVE][bext] fields, including embedded program
+  loudness, coding history and [SMPTE UMID][smpte_330m2011].
+* [iXML][ixml] production recorder metadata, including project, scene, and 
+  take tags, recorder notes and file family information.
+  * iXML `STEINBERG` sound library attributes.
+* All known [RIFF INFO][info-tags] metadata fields.
+* [Audio Definition Model (ADM)][adm] track metadata and schema, including 
+  channel, pack formats, 
+  object, content and programme, including [Dolby Digital Plus][ebu3285s6]
+  and Dolby Atmos `dbmd` metadata for re-renders and mixdowns.
+* Wave embedded [cue markers][cues], cue marker labels, notes and timed ranges as used
+  by Zoom, iZotope RX, etc.
+* Wave embedded [sampler][smpl] and sample loop metadata.
+* The [wav format][format] is also parsed, so you can access the basic sample rate 
+  and channel count information.

+## How To Use
 
 The entry point for wavinfo is the WavInfoReader class.
 
@@ -40,117 +58,24 @@ from wavinfo import WavInfoReader
 path = '../tests/test_files/A101_1.WAV'
 
 info = WavInfoReader(path)
+
+adm_metadata = info.adm
+ixml_metadata = info.ixml
 ```
 
-### Basic WAV Data
+The package also installs a shell command:
 
-The length of the file in frames (interleaved samples) and bytes is available, as is the contents of the format chunk.
-
-```python
-(info.data.frame_count, info.data.byte_count)
->>> (240239, 1441434)
-(info.fmt.sample_rate, info.fmt.channel_count, info.fmt.block_align, info.fmt.bits_per_sample)
->>> (48000, 2, 6, 24)
+```sh
+$ wavinfo test_files/A101_1.WAV
 ```
 
-### Broadcast WAV Extension
+## Contributions!
 
-A WAV file produced to Broadcast-WAV specifications will have the broadcast metadata extension,
-which includes a 256-character free text descrption, creating entity identifier (usually the 
-recording application or equipment), the date and time of recording and a time reference for 
-timecode synchronization.
-
-The `coding_history` is designed to contain a record of every conversion performed on the audio
-file.
-
-In this example (from a Sound Devices 702T) the bext metadata contains scene/take slating
-information in the `description`. Here also the `originator_ref` is a serial number conforming
-to EBU Rec 99.
-
-If the bext metadata conforms to EBU 3285 v1, it will contain the WAV's 32 or 64 byte SMPTE 
-330M UMID. The 32-byte version of the UMID is usually just a random number, while the 64-byte 
-UMID will also have information on the recording date and time, recording equipment and entity, 
-and geolocation data.
-
-If the bext metadata conforms to EBU 3285 v2, it will hold precomputed program loudness values
-as described by EBU Rec 128.
-
-```python
-print(info.bext.description)
-print("----------")
-print("Originator:", info.bext.originator)
-print("Originator Ref:", info.bext.originator_ref)
-print("Originator Date:", info.bext.originator_date)

-### iXML Production Recorder Metadata
-
-iXML allows an XML document to be embedded in a WAV file.
-
-The iXML website recommends a schema for recorder information but 
-there is no official DTD and vendors mostly do their own thing, apart from 
-hitting a few key xpaths. iXML is used by most location/production recorders

+Using `wavinfo` from the Command Line
+=====================================
+
+`wavinfo` installs a command-line entry point that will read wav files
+from the command line and output metadata to stdout.
+
+.. code-block:: shell
+
+    $ wavinfo [[-i] | [--ixml | --adm]] INFILE +
+
+
+Options
+-------
+
+By default, `wavinfo` will output a JSON dictionary for each file argument.
+
+``-i`` 
+    `wavinfo` will run in `interactive mode`_.
+
+Two option flags will change the behavior of the command in non-interactive 
+mode:
+
+``--ixml``
+    The *\-\-ixml* flag will cause `wavinfo` to output the iXML metadata
+    payload of each input wave file, or will emit an error message to stderr if
+    iXML metadata is not present.
+
+``--adm``
+    The *\-\-adm* flag will cause `wavinfo` to output the ADM XML metadata 
+    payload of each input wave file, or will emit an error message to stderr if
+    ADM XML metadata is not present.
+
+These options are mutually-exclusive, with `\-\-adm` taking precedence. The 
+``--ixml`` and ``--adm`` flags futher take precedence over ``-i``.
+
+
+Interactive Mode 
+-----------------
+
+In interactive mode, `wavinfo` will present a command prompt which allows you
+to query the files provided on the command line and explore the metadata tree 
+interactively. Each file on the command line is scanned and presented as a 
+tree of metadata records.
+
+Commands include:
+
+``ls``
+    List the available metadata keys at the current level.
+
+``cd``
+    Traverse to a metadata key in the current level (or enter `..` to go up 
+    to the prevvious level).
+
+``bye``
+    Exit to the shell.
+
+Type `help` or `?` at the prompt to get a full list of commands.
+
+
+Example Output
+--------------
+
+.. attention::
+
+   Metadata fields containing binary data, such as the Broadcast-WAV UMID, will 
+   be included in the JSON output as a base-64 encoded string, preceded by the
+   marker "base64:".

+ADM (Audio Definition Model) Metadata
+=====================================
+
+Notes
+-----
+
+`ADM metadata`_ is used in master recordings to describe the format and content 
+of the tracks. In practice on wave files, ADM tells a client which tracks are 
+members of multichannel stems or "beds" and their speaker assignment, and which 
+tracks are freely-positioned 3D objects. ADM also records the panning moves on
+object tracks and their content group ("Dialogue", "Music", "Effects" etc.)
+
+ADM wave files created with a Dolby Rendering and Mastering Unit are a common 
+deliverable in feature film and television production. The `Dolby Atmos ADM Profile`_ 
+describes how the RMU translates its native Master format into ADM.

+Broadcast WAV Extension Metadata
+================================
+
+
+Notes
+-----
+A WAV file produced to Broadcast-WAV specifications will have the broadcast
+metadata extension, which includes a 256-character free text descrption,
+creating entity identifier (usually the recording application or equipment),
+the date and time of recording and a time reference for timecode
+synchronization.
+
+The :py:attr:`coding_history<wavinfo.wave_bext_reader.WavBextReader.coding_history>` 
+is designed to contain a record of every conversion performed on the audio file.
+
+In this example (from a Sound Devices 702T) the bext metadata contains
+scene/take slating information in the
+:py:attr:`description<wavinfo.wave_bext_reader.WavBextReader.description>`. 
+Here also the
+:py:attr:`originator_ref<wavinfo.wave_bext_reader.WavBextReader.originator_ref>`
+is a serial number conforming to EBU Rec 99.
+
+If the bext metadata conforms to `EBU 3285 v1`_, it will contain the WAV's 32
+or 64 byte `SMPTE ST 330 UMID`_. The 32-byte version of the UMID is usually
+just a random number, while the 64-byte UMID will also have information on the
+recording date and time, recording equipment and entity, and geolocation data.
+
+If the bext metadata conforms to `EBU 3285 v2`_, it will hold precomputed
+program loudness values as described by `EBU Rec 128`_.
+
+.. _EBU 3285 v1: https://tech.ebu.ch/publications/tech3285s1
+.. _SMPTE ST 330 UMID: https://standards.globalspec.com/std/1396751/smpte-st-330
+.. _EBU 3285 v2: https://tech.ebu.ch/publications/tech3285s2
+.. _EBU Rec 128: https://tech.ebu.ch/publications/r128
+
+
+.. note::
+   All text fields in the Broadcast-WAV metadata structure are decoded by 
+   default as flat ASCII. To override this and use a different encoding, pass
+   an string encoding name to the ``bext_encoding`` parameter of
+   :py:meth:`WavInfoReader()<wavinfo.wave_reader.WavInfoReader.__init__>`
