Detailed Description

This reader limits another reader in start and end sample.

Definition at line 40 of file AUD_LimiterReader.h.


Constructor & Destructor Documentation

AUD_LimiterReader::AUD_LimiterReader ( AUD_IReader reader,
float  start = 0,
float  end = -1 
)

Creates a new limiter reader.

Parameters:
readerThe reader to read from.
startThe desired start sample (inclusive).
endThe desired end sample (exklusive), a negative value signals that it should play to the end.

Member Function Documentation

int AUD_LimiterReader::getLength ( ) const [virtual]

Returns an approximated length of the source in samples. For readers of the type buffer this has to return a correct value!

Returns:
The length as sample count. May be negative if unknown.
See also:
getType

Reimplemented from AUD_EffectReader.

Definition at line 69 of file AUD_LimiterReader.cpp.

References AUD_IReader::getLength(), and AUD_EffectReader::m_reader.

int AUD_LimiterReader::getPosition ( ) const [virtual]

Returns the position of the source as a sample count value.

Returns:
The current position in the source. A negative value indicates that the position is unknown.
Warning:
The value returned doesn't always have to be correct for readers of the stream type, especially after seeking, it must though for the buffer ones.
See also:
getType

Reimplemented from AUD_EffectReader.

void AUD_LimiterReader::read ( int &  length,
sample_t *&  buffer 
) [virtual]

Request to read the next length samples out of the source. The buffer for reading has to stay valid until the next call of this method or until the reader is deleted.

Parameters:
[in,out]lengthThe count of samples that should be read. Shall contain the real count of samples after reading, in case there were only fewer samples available. A smaller value also indicates the end of the reader.
[out]bufferThe pointer to the buffer with the samples.

Reimplemented from AUD_EffectReader.

Definition at line 83 of file AUD_LimiterReader.cpp.

References AUD_IReader::getPosition(), AUD_EffectReader::m_reader, and AUD_IReader::read().

void AUD_LimiterReader::seek ( int  position) [virtual]

Seeks to a specific position in the source. This function must work for buffer type readers.

Parameters:
positionThe position to seek for measured in samples. To get from a given time to the samples you simply have to multiply the time value in seconds with the sample rate of the reader.
Warning:
This may work or not, depending on the actual reader.
