class | FrameFactory |
This is an implementation of ID3v2 relative volume adjustment. The presense of this frame makes it possible to specify an increase in volume for an audio file or specific audio tracks in that file.
Multiple relative volume adjustment frames may be present in the tag each with a unique identification and describing volume adjustment for different channel types.
|
|
Constructs a RelativeVolumeFrame. The relevant data should be set manually. |
|
Constructs a RelativeVolumeFrame based on the contents of data. |
|
Destroys the RelativeVolumeFrame instance. |
|
Returns a list of channels with information currently in the frame. |
|
|
|
Called by parse() to parse the field data. It makes this information available through the public API. This must be overridden by the subclasses. Implements TagLib::ID3v2::Frame. |
|
Returns the peak volume (represented as a length and a string of bits). This defaults to returning the value for the master volume channel if available and returns 0 if the specified channel does not exist.
|
|
Render the field data back to a binary format in a ByteVector. This must be overridden by subclasses. Implements TagLib::ID3v2::Frame. |
|
|
|
Sets the peak volume to peak. By default this sets the value for the master volume.
|
|
Set the relative volume adjustment in decibels to adjustment. By default this sets the value for the master volume.
|
|
Set the volume adjustment to index. As indicated by the ID3v2 standard this is a 16-bit signed integer that reflects the decibils of adjustment when divided by 512. By default this sets the value for the master volume.
|
|
Returns the frame's identification.
Implements TagLib::ID3v2::Frame. |
|
Returns the relative volume adjustment in decibels.
|
|
Returns the relative volume adjustment "index". As indicated by the ID3v2 standard this is a 16-bit signed integer that reflects the decibils of adjustment when divided by 512. This defaults to returning the value for the master volume channel if available and returns 0 if the specified channel does not exist.
