Uint64 sampleCount
Total number of samples in the file.
Abstract class for custom file input streams.
Definition: InputStream.hpp:40
virtual Uint64 read(Int16 *samples, Uint64 maxCount)=0
Read audio samples from the open file.
unsigned int sampleRate
Samples rate of the sound, in samples per second.
virtual bool open(InputStream &stream, Info &info)=0
Open a sound file for reading.
unsigned int channelCount
Number of channels of the sound.
virtual void seek(Uint64 sampleOffset)=0
Change the current read position to the given sample offset.
virtual ~SoundFileReader()
Virtual destructor.
Structure holding the audio properties of a sound file.
Abstract base class for sound file decoding.
