These are the fields displayed in the Audio Tab within the Edit Pane, this is for our information only you cannot modify these values.
Audio Size
This is the size of the file
AudioFormat
This shows the audio format. For example for MP3s this combines the MPEG Version and Layer. The version is related to the sampling rate the original file was sampled at. Most music and audio book tracks use Version 1 which can sample information at CD quality (44Mhz), whereas Version 2 and Version 2.5 can be used to sample at lower rates, typically they are used in niche applications such as sampling sound effects. For MP3 the layer will always be three, MP2 would have a value of two, and MP1 files would have a value of one.
Audio Bit Rate
This displays the sampling rate used to create this file,usually the higher the bit rate the better quality the encoding. If variable bit rate is used it will be shown in brackets after the average bit rate e.g. 192kbps (VBR)
Audio Playing Time
The length of the audio track in seconds
Audio Encoder
The encoder that encoded the track. For some audio formats (Ogg,Flac,Mp4) this fields can be modified by editing the Encoder field in the edit tab. MP3 files do not allow modification of this field, but you can set a corresponding field in the ID3 tag.

Audio Sample Rate
This displays the sampling rate of the original audio source
Audio Is Copyright
Is this Audio File copyrighted (MP3 only)
Audio Is Original
Is this the original Audio File (MP3 only)
Audio Is Private
Is this the Audio File private (MP3 only)
Audio Is Protected
Is this the Audio File protected (MP3 only)
Audio Is VBR
Is this Audio File encoded using Variable Bit Rate this means that the sampling rate varies depending on the content. This allows better quality encoding in smaller files.
