Using raw-format input today only 8/16 and 24 bits are supported!
This relates to the "bps=x" command-line option.

However, in your documentation you write, that any raw PCM sample format between 8 and 32 bit integer is supported.

So it would be great, if you could add 32-bit integer support (bps=32).

    I would like to see this feature too. In fact wavpack can do 32-bit raw pcm so why not flac?

    Please add 32-bit integer support! Is it really that hard to implement? I have some lab data recorded in int32 format and I want to use flac to compress them. I've compared wavpack and flac and decided that flac generally provides 5~10% more compression without significant difference in en/decoding time. But right now I have to manually transform the data to int16 first to satisfy flac.

    I second the feature request. While rarely used, it would be a nice feature to have. Currently I have to use Wavpack if I want to compress 32-bit float or 32-bit integer files.
