### Technical Metadata

The Technical Metadata view displays information about each file (in either a CSV document or a table) including the file size, metadata from the <fmt > chunk, the existence of key metadata chunks, and file warnings.

Value Name | Description
--- | ---

FileName

In order to provide a concise presentation the filepaths are displayed from the directory path where the files diverge. Thus if two files are opened from /HardDrive1/audiofiles/music/audiofile.wav and /HardDrive1/audiofiles/spokenword/audiofileB.wav then these will be displayed in the table view as /music/audiofile.wav and /spokenword/audiofileB.wav since the /HardDrive1/audiofiles section of the Filepath is common to the open files.
The CSV version of the Technical Metadata view displays the full filepath to each file.

FileSize | The size of the audio file in bytes.

Format

This value represents the type of compression utilized within the audio data. Below is a sample of compression codes:

0000 | Unknown
0001 | PCM / Uncompressed
0002 | Microsoft ADPCM
0006 | ITU G.711 a-law
0007 | ITU G.711 Aµ-law
0011 | IMA ADPCM
0016 | ITU G.723 ADPCM (Yamaha)
0031 | GSM 6.10
0040 | ITU G.721 ADPCM
0050 | MPEG
FFFE | Extensible
FFFF | Experimental

Channels | The number of audio signals that are encoded in the audio data. A value of '1' indicates mono audio, '2' for stereo, etc.
SampleRate | The number of audio samples per second.
BitRate | The number of bits utilized per second of audio.
BitsPerSample | The number of bits utilized to produce one sample of audio.
Duration | The total playing time for the audio data, displayed in HH:MM:SS.mmm (hours, minutes, seconds, milliseconds)
Bext | This column notes the existence of the <bext> chunk by either stating 'No', 'Version 0' or 'Version 1' (indicated of the version of bext chunk utilized).
INFO | Notes the existence of the INFO chunk, either 'Yes' or 'No'.
XMP | Notes the existence of the XMP chunk, either 'Yes' or 'No'. Right-click on this cell provides options to Import, Export, or Remove xml data. Doubling-clicking on the cell brings a text editor. Changes are not made until the file is saved.
aXML | Notes the existence of the aXML chunk, either 'Yes' or 'No'. Right-click on this cell provides options to Import, Export, or Remove xml data. Doubling-clicking on the cell brings a text editor. Changes are not made until the file is saved.
iXML | Notes the existence of the iXML chunk, either 'Yes' or 'No'. Right-click on this cell provides options to Import, Export, or Remove xml data. Doubling-clicking on the cell brings a text editor. Changes are not made until the file is saved.
MD5 | If an MD5 chunk exists, this column will show the stored value. This MD5 value is a checksum of the audio data only (starting after the <data> chunk identifier and size) and does not include the file's metadata or any other chunk.
MD5 evaluated | If the MD5 is evaluated it will appear in this column. Any conflict between this column and the 'MD5' column indicates a change in the audio data portion of the file between the current evaluation and the stored evaluation.
Errors | Provides statements about potential structural problems with a given audio files: for instance if the RIFF size statement conflicts with the actual file size or if the audio files does not utilize padding bytes to follow odd byte length chunks.
Information | Used for status notes and technical information during operation.
