+# 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.
+

+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 [--ixml | --adm] INFILE +
+
+By default, `wavinfo` will output a JSON dictionary for each file argument.
+
+
+Options
+-------
+
+Two option flags will change the behavior of the command:
+
+``--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 (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

+iXML Production Recorder Metadata
+=================================

+Notes
+-----
+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 
+to save slating information, timecode and sync points in a reliable way.
+
+iXML is also used to link "families" of WAV files together, so WAV files
