Audio::TagLib::ID3v2::RelativeVolumeFrame::PeakVolume - Struct that stores the relevant values for ID3v2 peak volume
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"
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.
Constructs an empty peak volume description.
- UV bitsRepresentingPeak()
Returns the number of bits (in the range of 0 to 255) used to describe the peak volume.
- void setBitsRepresentingPeak(UV $b)
Sets the number of bits to $b, which is used to describe the peak volume.
- ByteVector peakVolume()
Returns the array of bits (represented as a series of bytes) used to describe the peak volume.
- void setPeakVolume(ByteVector $v)
Sets the array of bits to $v, which is used ot describe the peak volume.
None by default.
