nCine::AudioBuffer class
#include <nCine/Audio/AudioBuffer.h>

Fully decoded OpenAL audio buffer.

Holds an entire sound effect decoded into memory. Inherits from Object so a single buffer can be shared by multiple AudioBufferPlayer instances.

Base classes

static auto sType() -> ObjectType: Returns the static object type of this class.

AudioBuffer(): Creates an empty OpenAL buffer.
AudioBuffer(StringView filename) explicit: Creates a buffer and loads it from the specified file.
AudioBuffer(std::unique_ptr<Death::IO::Stream> fileHandle, StringView filename): Creates a buffer and loads it from an already opened stream.
~AudioBuffer() override
AudioBuffer(const AudioBuffer&) deleted
AudioBuffer(AudioBuffer&& other) noexcept

auto operator=(const AudioBuffer&) -> AudioBuffer& deleted
auto operator=(AudioBuffer&& other) -> AudioBuffer& noexcept
void init(Format format, std::int32_t frequency): Initializes an empty buffer with the specified format and frequency.
auto loadFromFile(StringView filename) -> bool: Loads audio data from the specified file.
auto loadFromStream(std::unique_ptr<Death::IO::Stream> fileHandle, StringView filename) -> bool: Loads audio data from an already opened stream.
auto loadFromSamples(const unsigned char* bufferPtr, std::int32_t bufferSize) -> bool: Loads samples in raw PCM format from a memory buffer.
auto bufferId() const -> std::uint32_t: Returns the OpenAL buffer id.
auto bytesPerSample() const -> std::int32_t: Returns the number of bytes per sample.
auto numChannels() const -> std::int32_t: Returns the number of audio channels.
auto frequency() const -> std::int32_t: Returns the sample frequency.
auto numSamples() const -> std::int32_t: Returns the total number of samples.
auto duration() const -> float: Returns the duration in seconds.
auto bufferSize() const -> std::int32_t: Returns the size of the buffer in bytes.
