Hi folks,
how to get from ogg file bits per sample (8bits or 16bits) ?
Full Version: Ogg get bits per sample
If you mean Vorbis, the decoded data is intrinsically floating point (libvorbis) or 16bits-or-more (Tremor), but the type of data gotten back from both the normal interfaces to these libraries is 16 bit.
10x man, I hope this is true

It is.
The decoding library returns floats, so it up to the decoder frontend to decide the bit depth to write at - normally this is 16 bit integer by default. This is really what aspifox has already said!!

Ok, but when I use ov_read(OggVorbis_File *vf, char *buffer, int length, int bigendianp, int word, int sgned, int *bitstream);
word
Specifies word size. Possible arguments are 1 for 8-bit samples, or 2 or 16-bit samples. Typical value is 2.
How to understand how ogg file (8bits or 16bits) is coded?
Sorry for my english :/

Internally, the encoded data is in floats. If you want full flexibility, you can use ov_read_float and you'll receive the decoded data in float format so you can then do with it as you will.
