=head1 NAME

Audio::TagLib::ID3v2::RelativeVolumeFrame::PeakVolume - Struct that stores
the relevant values for ID3v2 peak volume 

=head1 SYNOPSIS

  use Audio::TagLib::ID3v2::RelativeVolumeFrame::PeakVolume;
  
  my $i = Audio::TagLib::ID3v2::RelativeVolumeFrame::PeakVolume->new();
  $i->setBitsRepresentingPeak(20);
  print $i->bitsRepresentingPeak(), "\n"; # got 20
  $i->setPeakVolume(Audio::TagLib::ByteVector->new("1111"));
  print $i->peakVolume()->data(), "\n"; # got "1111"

=head1 DESCRIPTION

The peak volume is described as a series of bits that is padded to
fill a block of bytes. These two values should always be updated in
tandem. 

=over

=item I<new()>

Constructs an empty peak volume description.

=item I<UV bitsRepresentingPeak()>

Returns the number of bits (in the range of 0 to 255) used to describe
the peak volume.

=item I<void setBitsRepresentingPeak(UV $b)>

Sets the number of bits to $b, which is used to describe the peak
volume. 

=item I<L<ByteVector|Audio::TagLib::ByteVector> peakVolume()>

Returns the array of bits (represented as a series of bytes) used to
describe the peak volume.

=item I<void setPeakVolume(L<ByteVector|Audio::TagLib::ByteVector> $v)>

Sets the array of bits to $v, which is used ot describe the peak
volume.
