Embedded Sound Files.

cannam@125: cannam@125:

cannam@125: By using the open SNDFILE with a file descriptor function: cannam@125:

cannam@125: cannam@125:

cannam@125:       SNDFILE*  sf_open_fd (int fd, int mode, SF_INFO *sfinfo, int close_desc) ;
cannam@125:

cannam@125: cannam@125:

cannam@125: it is possible to open sound files embedded within larger files. cannam@125: There are however a couple of caveats: cannam@125:

cannam@125: cannam@125:

Read/Write mode (SFM_RDWR) is not supported. cannam@125:
Writing of embedded files is only supported at the end of the file. cannam@125:
Reading of embedded files is only supported at file offsets greater cannam@125: than zero. cannam@125:
Not all file formats are supported (currently only WAV, AIFF and AU). cannam@125:

cannam@125: cannam@125:

cannam@125: The test program multi_file_test.c in the tests/ directory of the cannam@125: source code tarball shows how this functionality is used to read and write cannam@125: embedded files. cannam@125:
