Functions
AudioData	nk::audio::audioreadFromBytes (const std::uint8_t *data, std::size_t len, int64_t startSample=1, int64_t endSample=-1, bool nativeType=false, std::pmr::memory_resource *mr=nullptr)
	Decodes audio from raw memory buffer, sniffing format automatically ([y, Fs] = audioread(bytes)).
AudioData	nk::audio::audioreadFromBytes (const std::string &bytes, int64_t startSample=1, int64_t endSample=-1, bool nativeType=false, std::pmr::memory_resource *mr=nullptr)
	Decodes audio from string memory buffer (audioread(bytes)).
AudioInfo	nk::audio::audioinfoFromBytes (const std::uint8_t *data, std::size_t len)
	Reads audio metadata from memory buffer without decoding audio samples (info = audioinfo(bytes)).
AudioInfo	nk::audio::audioinfoFromBytes (const std::string &bytes)
	Reads audio metadata from string memory buffer (info = audioinfo(bytes)).
std::vector< std::uint8_t >	nk::audio::audiowriteToBytes (const Value &y, double sampleRate, const std::string &format="wav", uint16_t bitsPerSample=16, const std::string &title="", const std::string &artist="", const std::string &comment="")
	Encodes audio matrix y into memory byte buffer (bytes = audiowrite(y, Fs, ...)).
AudioData	nk::audio::audioread (const std::string &path, int64_t startSample=1, int64_t endSample=-1, bool nativeType=false, std::pmr::memory_resource *mr=nullptr)
	Reads audio file from filesystem ([y, Fs] = audioread(filename)).
AudioInfo	nk::audio::audioinfo (const std::string &path)
	Returns audio file metadata (info = audioinfo(filename)).
void	nk::audio::audiowrite (const std::string &path, const Value &y, double sampleRate, uint16_t bitsPerSample=16, const std::string &title="", const std::string &artist="", const std::string &comment="")
	Writes audio data matrix y to file on disk (audiowrite(filename, y, Fs)).
