#91 32-bit raw input support


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.

    I want Flac support for the 32bit integer,too! Please!
    Now there are high Resolution Audio which is 32bit integer sales online in Japan.

      Are you sure its 32 bit Integer and not 32 bit float? The only one I can find is the following which is clearly 32 bit float : http://ototoy.jp/_/default/p/50962

        yeah , in 32bit integer.

    I hope Flac support 32bit bit depth. Recently,Hi-res is important for Audio,and 32bit's format sales online. Please modify algorithm to supprot 32bit integer files. Thank you!!!
