AVorbisSoundPipe::write
void write(const char *src, size_t size) override
Writes exact size bytes to stream. Blocking (waiting for write all data) is allowed.

AVorbisSoundPipe::read
size_t read(char *dst, size_t) override
Reads up to size bytes from stream. Blocking (waiting for new data) is allowed.

AVorbisSoundPipe::info
AAudioFormat info() override
Get general info about sound stream.

ISoundPipe
ISoundPipe accepts sound data and outputs sound samples, useful for decoded audio passed in packets.

ASampleFormat
ASampleFormat
Sample formats supported for mixing.
Definition ASampleFormat.h:12

ASampleFormat::I16
@ I16
Signed 16-bit integer.
Definition ASampleFormat.h:16

AAudioFormat
Audio format descriptor.
