Field Size Field Description CATC Data
SampleRate Little 24 4 The number of sample
slices per second. This
value is unaffected by the
number of channels:
8000, 44100, etc. Sample Rate as
selected by the
user: 8K or 64K
ByteRate Little 28 4 This value indicates how
many bytes of wave data
must be streamed to a
D/A converter per second
in order to play the wave
file. This information is
useful when determining
if data can be streamed
from the source fast
enough to keep up with
playback. This value can
be easily calculated with
the formula: SamplesPerSec
*.BlockAlign
BlockAlign Little 32 2 The number of bytes for
one sample including all
channels. Channels *
(BitsPerSample /
8 )
BitPerSample Little 34 2 This value specifies the
number of bits used to
define each sample. This
value is usually 8, 16, 24
or 32. 16
ExtraParamSize Little 36 2 This value specifies how
many additional format
bytes follow. It does not
exist if the compression
code is 0 (uncompressed
PCM file) but may exist
and have any value for
other compression types
depending on what
compression information
is need to decode the
wave data. If this value is
not word aligned (a
multiple of 2), padding
should be added to the
end of this data to word
align it, but the value
should remain
non-aligned. 0
