# The Audio Edit Panel

This display presents information relating, at least to a large extent, to the audio files themselves. Not all these fields are present for every file type.

As these fields are not as common as many others, a brief description of the fields and their editing requirements follows. This text is largely taken from the ID3 specifications:

> Media Type
>   This field describes from which media the sound originated. The recommended formatting for this field type is not enforced. The pull down menu is a quick means of choosing Apple media kind values. When the field is set to Podcast, mp3 and MPEG-4 files will set the appropriate low level metadata to ensure that iTunes (not Music) recognizes the track as a podcast when it is added. Note that iTunes requires mp3 files to have a podcast url in order to be recognized. For mp3 and MPEG-4 files Yate maps the Podcast URL field to the appropriate low level metadata. If the URL data is not specified for an mp3 podcast, Yate will supply a dummy value. It may be possible to force specific Media Kind values into an Apple application. This can be attempted by using the Export to Apple App action statement. In MPEG-4 files the field controls how a file is added to an Apple application. Acceptable values are:

>   > iTunes
>   >   Audiobook, Booklet, Home Video, Movie, Music, Music Video, Ringtone, TV Show. Any other value is treated as Music.
>   > Music
>   >   Music and Music Video. Any other value is treated as Music.
>   > TV
>   >   Home Video, Movie, and TV Show. Any other value is treated as Home Video.

> File Type
>   This field indicates which type of audio this tag defines. The recommended formatting for this field type is not enforced. In fact you can elect to automatically set this field to be the filename extension of the file when the file is loaded. See Audio Preferences.
> Encoded By
>   This field contains the name of the person or organisation that encoded the audio file. In FLAC/OGG files, this field is the default mapping to the vendor identification. See Preferences - FLAC/OGG Mappings for additional information on the writing of this field.
> Encoder Settings
>   This field describes the used audio encoder and its settings when the file was encoded. Hardware refers to hardware encoders, not the computer on which a program was run.
> Play Count
>   This is simply a counter of the number of times a file has been played. Using the Link to Apple functionality Yate can synchronize this information with an Apple application.
> Playlist Delay
>   This field defines the numbers of milliseconds of silence that should be inserted before this audio. The value zero indicates that this is a part of a multifile audio track that should be played continuously.
> Length
>   This field contains the length of the audio file in milliseconds. This field can be automatically set when a file is loaded. See Audio Preferences. Nore there is no requirement for the field to be set.
> Encoding Time
>   The field contains a timestamp describing when the audio was encoded.
> Music CD Identifier
>   This field is intended for music that comes from a CD, so that the CD can be identified in databases such as the CDDB [CDDB]. The field consists of a binary dump of the Table Of Contents, TOC, from the CD. Note that the formatting is enforced when outputting ID3 based files.
> Reverb
>   This field lets you adjust echoes of different kinds. Yate does not provide a dedicated editor for this field, but does allow you to manually enter the field's binary data. A more detailed description is given in the context help for the field's advanced editor.
> ISRC
>   The ISRC field should contain the International Standard Recording Code [ISRC] (12 characters).
> Start Time
>   This field is used to store an Apple application's Start Time data. The field is formatted as hh:mm:ss.ttt where any component may be omitted. ttt is thousandths of a second.
> Stop Time
>   This field is used to store an Apple application's Stop Time data. The field is formatted as hh:mm:ss.ttt where any component may be omitted. ttt is thousandths of a second. Setting the value to zero will restore the default stop time.
> Volume Adjustment
>   This field is used to store an Apple application's Volume Adjustment data. While you can enter any data in this field, it is always normalized before being exported. Valid values are -97 through 99, representing the percentage change.
> Remember Position
>   This field is used to store an Apple application's Remember Playback Position data. The field is not valid for APE, DFF, DSF, FLAC, OGG and WayPack files. When setting the value in an action, use 1 for set and 0 for cleared.
> Unhandled Items
>   If any Unhandled Items are present in the audio file a link will be displayed which will take you to the appropriate content view.
> Equalization
>   If any Equalization items are present in the audio file a link will be displayed which will take you to the appropriate content view.
> Relative Volume Adjustment
>   If any Relative Volume Adjustment items are present in the audio file a link will be displayed which will take you to the appropriate content view.

The following fields are read only and describe information extracted from the file. These values are only displayed when there is a single file selected. Note that when a single Stem file (stem.mp4) is selected, double clicking in the audio information table will display the stem metadata. This information is only extracted for audio tracks. MPEG-4 files with video and no audio will display empty values. Note also that when a single WAV file which contains BEXT Metadata is selected, double clicking in the audio information panel will display the BEXT data. A popup version of this panel can be displayed at any time by right clicking on a file and selecting Audio Information from the context menu or by selecting a single file and doing a View>Audio Information.

> Bit Rate (kbits/sec)
>   The field displays the audio stream bit rate in kbits/sec.
> Sample Rate (Hz)
>   The field displays the audio stream sample rate in Hz.
> Channel Mode
>   The field displays the audio stream channel mode.
> Time
>   The field displays the play time of the track.
> File Size (kbits/sec)
>   The size of the file.
> Free Space (Hz)
>   The amount of free space in the file.
> Stream
>   The field displays the format of the data stream.
> Tag Scheme
>   This field describes the tag schemes found in the file and optionally the type of header found in an MP3 file (Xing, Info). The following may be displayed:
>   ID3 1
>     The file contained an ID3 v1 tag
>   ID3 2.n
>     The file contained an ID3 v2.n tag
>   ID3 2.n,1
>     The file contained an ID3 v2.n and v1 tag
>   Xing
>     The MP3 file contained a Xing header
>   Info
>     The MP3 file contained an Info header
>   APE n
>     The file contained an APE version n tag
>   APE n,H
>     The file contained an APE version n tag which had a header
>   Vorbis
>     The file contained Vorbis comments used by FLAC and OGG files
>   MPEG-4
>     The file is an MPEG-4 container. For space reasons this is not displayed for files containing video.
> Leading Pad
>   If an mp3 file has unnecessary data befroe the start of the audio stream, the size is presented here.
> Creation Date
>   The date the file was created.
> Creation Time
