## Usage

tinytag only provides the minimum needed for _reading_ metadata, and presents
it in a simple format. It can determine track number, total tracks, title,
artist, album, year, duration and more.

```python
from tinytag import TinyTag
tag: TinyTag = TinyTag.get('/some/music.mp3')

print(f'This track is by {tag.artist}.')
print(f'It is {tag.duration:.2f} seconds long.')
```

> [!WARNING]  
> The `ignore_errors` parameter of `TinyTag.get()` is obsolete as of tinytag
> 2.0.0, and will be removed in the future.

Alternatively you can use tinytag directly on the command line:

    $ python3 -m tinytag /some/music.mp3
    {
      "filename": "/some/music.mp3",
      "filesize": 3243226,
      "duration": 173.52,
      "channels": 2,
      "bitrate": 128,
      "samplerate": 44100,
      "artist": [
        "artist name"
      ],
      "album": [
        "album name"
      ],
      "title": [
        "track name"
      ],
      "track": 4,
      "genre": [
        "Jazz"
      ],
      "year": [
        "2010"
      ],
      "comment": [
        "Some comment here"
      ]
    }

Check `python3 -m tinytag --help` for all CLI options, for example other
output formats.

### Supported Files

To receive a tuple of file extensions tinytag supports, use the
`SUPPORTED_FILE_EXTENSIONS` constant:

```python
TinyTag.SUPPORTED_FILE_EXTENSIONS
```

Alternatively, check if a file is supported by providing its path:

```python
is_supported = TinyTag.is_supported('/some/music.mp3')
```

### Common Metadata

tinytag provides some common attributes, which always contain a single value.
These are helpful when you need quick access to common metadata.

#### File/Audio Properties

    tag.bitdepth      # bit depth as integer (for lossless audio)
    tag.bitrate       # bitrate in kBits/s as float
    tag.duration      # audio duration in seconds as float
    tag.filename      # filename as string
    tag.filesize      # file size in bytes as integer
    tag.samplerate    # samples per second as integer

> [!WARNING]  
> The `tag.audio_offset` attribute is obsolete as of tinytag 2.0.0, and will
> be removed in the future.

#### Metadata Fields

    tag.album         # album as string
    tag.albumartist   # album artist as string
    tag.artist        # artist name as string
    tag.comment       # file comment as string
    tag.composer      # composer as string
    tag.disc          # disc number as integer
    tag.disc_total    # total number of discs as integer
    tag.genre         # genre as string
    tag.title         # title of the song as string
    tag.track         # track number as integer
    tag.track_total   # total number of tracks as integer
    tag.year          # year or date as string

### Additional Metadata

For additional values of the same field type, uncommon metadata fields, or
metadata specific to certain file formats, use `other`:

    tag.other         # a dictionary of additional fields

> [!WARNING]  
> The `other` dictionary has replaced the `extra` dictionary in tinytag 2.0.0.
> The latter will be removed in a future release.

The following `other` field names are standardized in tinytag, and optionally
present when files provide such metadata:

    barcode
    bpm
    catalog_number
    conductor
    copyright
    director
    encoded_by
    encoder_settings
    grouping
    initial_key
    isrc
    language
    license
    lyricist
    lyrics
    media
    movement
    movement_name
    movement_total
    publisher
    set_subtitle
    show_movement
    url
    work

Additional `other` field names not documented above may be present, but are
format-specific and may change or disappear in future tinytag releases. If
tinytag does not expose metadata you need, or you wish to standardize more
field names, open a feature request on GitHub for discussion.

`other` values are always provided as strings, and are not guaranteed to be
valid. Should e.g. the `bpm` value in the file contain non-numeric characters,
tinytag will provide the string as-is. It is your responsibility to handle
possible exceptions, e.g. when converting the value to an integer.

Multiple values of the same field type are provided if a file contains them.
Values are always provided as a list, even when only a single value exists.

Example:

```python
from tinytag import OtherFields, TinyTag

tag: TinyTag = TinyTag.get('/some/music.mp3')
other_fields: OtherFields = tag.other
catalog_numbers: list[str] | None = other_fields.get('catalog_number')

if catalog_numbers:
    catalog_number: str = catalog_numbers[0]
    print(catalog_number)

print(catalog_numbers)
```

Output:

    > 10
    > ['10']

When a file contains multiple values for a [common metadata field](#common-metadata)
(e.g. `artist`), the primary value is accessed through the common attribute
(`tag.artist`), and any additional values through the `other` dictionary
(`tag.other['artist']`).

Example:

```python
from tinytag import TinyTag

tag: TinyTag = TinyTag.get('/some/music.mp3')
artist: str | None = tag.artist
additional_artists: list[str] | None = tag.other.get('artist')

print(artist)
print(additional_artists)
```

Output:

    > main artist
    > ['another artist', 'yet another artist']

### All Metadata

If you need to receive all available metadata as key-value pairs in a flat
dictionary, use the `as_dict()` method. This combines the common attributes
and `other` dictionary, which can be more convenient in some cases.

    from tinytag import TinyTag

    tag: TinyTag = TinyTag.get('/some/music.mp3')
    metadata: dict = tag.as_dict()

### Images

Additionally, you can also read embedded images by passing a `image=True`
keyword argument to `TinyTag.get()`.

If you need to receive an image of a specific kind, including its description,
use `images`:

    tag.images        # available embedded images

The following common image attributes are available, providing the first
located image of each kind:

    tag.images.front_cover  # front cover as 'Image' object
    tag.images.back_cover   # back cover as 'Image' object
    tag.images.media        # media (e.g. CD label) as 'Image' object

When present, any additional images are available in an `images.other`
dictionary, using the following standardized key names:

    generic
    icon
    alt_icon
    front_cover
    back_cover
    media
    leaflet
    lead_artist
    artist
    conductor
    band
    composer
    lyricist
    recording_location
    during_recording
    during_performance
    screen_capture
    bright_colored_fish
    illustration
    band_logo
    publisher_logo
    unknown

Provided values are always lists containing at least one `Image` object.

The `Image` object provides the following attributes:

    data           # image data as bytes
    name           # image name/kind as string
    mime_type      # image MIME type as string
    description    # image description as string

To receive any available image, prioritizing the front cover, use `images.any`:

```python
from tinytag import Image, TinyTag

tag: TinyTag = TinyTag.get('/some/music.ogg', image=True)
image: Image | None = tag.images.any

if image is not None:
    data: bytes = image.data
    name: str = image.name
    mime_type: str = image.mime_type
    description: str = image.description

    print(len(data))
    print(name)
    print(mime_type)
    print(description)
```

Output:

    > 74452
    > front_cover
    > image/jpeg
    > some image description

> [!WARNING]  
> `tag.images.any` has replaced `tag.get_image()` in tinytag 2.0.0.
> `tag.get_image()` will be removed in the future.

To receive a common image, e.g. `front_cover`:

```python
from tinytag import Image, Images, TinyTag

tag: TinyTag = TinyTag.get('/some/music.ogg', image=True)
images: Images = tag.images
cover_image: Image = images.front_cover

if cover_image is not None:
    data: bytes = cover_image.data
    description: str = cover_image.description
```

To receive an additional image, e.g. `bright_colored_fish`:

```python
from tinytag import Image, OtherImages, TinyTag

tag: TinyTag = TinyTag.get('/some/music.ogg', image=True)
other_images: OtherImages = tag.images.other
fish_images: list[Image] | None = other_images.get('bright_colored_fish')

if fish_images:
    image = fish_images[0]  # Use first image
    data = image.data
    description = image.description
```

### Encoding

To open files using a specific encoding, you can use the `encoding` parameter.
This parameter is however only used for formats where the encoding is not
explicitly specified.

```python
TinyTag.get('a_file_with_gbk_encoding.mp3', encoding='gbk')
```

### File-like Objects

To use a file-like object (e.g. BytesIO) instead of a file path, pass a
`file_obj` keyword argument:

```python
TinyTag.get(file_obj=your_file_obj)
```

### Exceptions

    TinyTagException        # Base class for exceptions
    ParseError              # Parsing an audio file failed
    UnsupportedFormatError  # File format is not supported
