WAVEBANKENTRY

Contains the entry information from an XACT wave bank.

typedef struct WAVEBANKENTRY {
    union {
        struct {
            DWORD dwFlags : 4;
            DWORD Duration : 28;
        };
        DWORD dwFlagsAndDuration;
    };

    WAVEBANKREGION PlayRegion;
    WAVEBANKSAMPLEREGION LoopRegion;
} WAVEBANKENTRY, *LPWAVEBANKENTRY;

Members

dwFlags

Flags for the wave bank entry. Can be the following values.

Value	Description
WAVEBANKENTRY_FLAGS_READAHEAD	Indicates stream read-ahead is enabled.
WAVEBANKENTRY_FLAGS_LOOPCACHE	Indicates one or more looping sounds use this wave.
WAVEBANKENTRY_FLAGS_REMOVELOOPTAIL	Indicates removal of data after the end of the loop region.

Duration

Duration of the wave, in units of one sample. For instance, a ten second long wave sampled at 48KHz would have a duration of 480,000. This value is not affected by the number of channels, the number of bits per sample, or the compression format of the wave.

dwFlagsAndDuration

DWORD value representing both the flags and duration.

Format

WAVEBANKMINIWAVEFORMAT structure describing the mini-wave format for the wave bank entry.

PlayRegion

WAVEBANKREGION structure that describes the region within the wave data segment that contains this entry.

LoopRegion

WAVEBANKSAMPLEREGION structure that describes the region within the wave data (in samples) that should loop.
