Support - (fb2k) / Re: Newer foobar2000 Versions and 'fact' Chunks
Last post by Nick.C -From the same document:
"This chunk is required for all WAVE formats other than WAVE_FORMAT_PCM. It stores file
dependent information about the contents of the WAVE data. It currently specifies the time length of the
data in samples."
Which, to my reading, can be read as the chunk not being needed for PCM at all and that its contents are not fixed (noting the use of "currently" in relation to what is contained in the chunk).
