[linux-audio-dev] libsndfile: type combinations and string data

hi erik, i've got a question regarding type combinations in libsndfile: SF_FORMAT_FLOAT | SF_ENDIAN_CPU works with SF_FORMAT_AU on any platform, which is great. but it doesn't work with neither aiff nor wav. i expected that it would work with one of the both formats, depending on the host endianess. is there a special reason why it does not? some other questions regarding string data: snd does not explicitly allow using string data in the file format. however, i remember that it was done in the old NeXT days by increasing the data offset and using the space in between for a comment. do you think this could be implemented in libsndfile for the SF_STR_COMMENT thing or is that just too non-standard? with SF_FORMAT_AIFF, i can't write string data to the file in SFM_RDWR mode. the call to sf_set_string() succeeds, but the actual data in the file is not changed. the call to sf_set_string() succeeds even when the file is in SFM_READ mode. with SF_FORMAT_WAV, a file with string data can't be opened with SFM_RDWR anymore. this means there is no way to change the audio data or the comment of the file without copying it? i guess there is a special reason for that... thanks very much for your patience... bests, martin
