yes indeed, sorry for the confusion. actually, it seems that the
behavior of sndfile is slightly different on powerpc64 G5 and powerpc
ibook G4 [1].
sndfile-play from 1.0.15-3 plays that file correctly on the G4.
unfortunately i don't have physical access to the G5 at the moment, so I
can only confirm that for the ibook.
many thanks, paul
[1] not sure why yet, but i found the following code successfull on all
files on g5, but failing for some (rare) files on g4 with the message:
Unable to open input file /tmp/double_bass_pizz1.wav.
Error. Bad format field in SF_INFO struct when openning a RAW file for read.

aubio_sndfile_t * new_aubio_sndfile_ro(const char* outputname) {
aubio_sndfile_t * f = AUBIO_NEW(aubio_sndfile_t);
SF_INFO sfinfo;
AUBIO_MEMSET(&sfinfo, 0, sizeof (sfinfo));
if (! (f->handle = sf_open (outputname, SFM_READ, &sfinfo))) {
AUBIO_ERR("Unable to open input file %s.\n", outputname);
AUBIO_ERR("%s\n",sf_strerror (NULL)); /* libsndfile err msg */
return NULL;
}
//...
return f;
}

correcting this, according to the example in sndfile-info.c, seems to be
more robust:
--
aubio_sndfile_t * new_aubio_sndfile_ro(const char* outputname) {
aubio_sndfile_t * f = AUBIO_NEW(aubio_sndfile_t);
SF_INFO sfinfo;
sfinfo.format = 0;
f->handle = sf_open (outputname, SFM_READ, &sfinfo);
if (f->handle == NULL) {
AUBIO_ERR("Unable to open input file %s.\n", outputname);
AUBIO_ERR("%s\n",sf_strerror (NULL)); /* libsndfile err msg */
return NULL;
}
//...
return f;
}
