# The Audio 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
>   The 'Media type' frame describes from which media the sound originated. The recommended formatting for this field type is not enforced. Note that MPEG-4 files can optionally use this field somewhat differently. For more information see the Preferences - Audio - Map stik atom to Media Type option. The pull down menu is a quick means of choosing iTunes 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 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 iTunes. This can be attempted by using the Export to iTunes action statement.
> File Type
>   The 'File type' frame 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
>   The 'Encoded by ' frame contains the name of the person or organisation that encoded the audio file.
> Encoder Settings
>   The 'Software/Hardware and settings used for encoding' frame includes 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 iTunes functionality Yate can synchronize this information with iTunes.
> Playlist Delay
>   The 'Playlist delay' 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
>   The 'Length' frame contains the length of the audio file in milliseconds. This field can be automatically set when a file is loaded. See Audio Preferences.
> Encoding Time
>   The 'Encoding time' frame contains a timestamp describing when the audio was encoded.
> Music CD Identifier
>   This frame is intended for music that comes from a CD, so that the CD can be identified in databases such as the CDDB [CDDB]. The frame 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 frame 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 frame is used to store the iTunes 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 frame is used to store the iTunes 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 frame is used to store the iTunes Volume Adjustment data. While you can enter any data in this field, it is always normalized before being exported to iTunes. Valid values are -97 through 99, representing the percentage change.
> Remember Position
>   This frame is used to store the iTunes Remember Playback Position data. The field is not valid for DFF, DSF or FLAC files. When setting the value in an action, use 1 for set and 0 for cleared.
> Unhandled Frames
>   If any Unhandled Frames 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 properties table will display the stem metadata.

> 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.
> Version/Hdr
>   The ID3 version and optionally the type of header found in the audio stream: Xing, Info or none. If no audio frames are detected in an mp3 file, this field will contain No Audio.
> 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
>   The time the file was created.
> Mod Date
>   The date the file was last modified.
> Mod Time
>   The time the file was last modified.
