Member Function Documentation

◆ close()

void pulp::audio::StreamingWriter::close ( )

Close the file (finalizes the WAV header with correct sizes).

◆ frames_written()

uint64_t pulp::audio::StreamingWriter::frames_written ( ) const

inline

Total frames written so far.

◆ is_open()

bool pulp::audio::StreamingWriter::is_open ( ) const

inline

Whether the writer is currently open.

◆ open()

bool pulp::audio::StreamingWriter::open	(	std::string_view	path,
		uint32_t	sample_rate,
		uint32_t	num_channels,
		uint32_t	bits_per_sample = 16 )

Open a file for streaming write.

sample_rate and num_channels must be known up front.

◆ operator=()

StreamingWriter & pulp::audio::StreamingWriter::operator= ( const StreamingWriter & )
