I can find fsb file struct like:  
typedef struct {  
char id[4]; /\* ‘FSB5’ _/  
int32\_t version; // ???  
int32\_t numsamples; /_ number of samples in the file _/  
int32\_t shdrsize; /_ size in bytes of all of the sample headers including extended information _/  
int32\_t namesize; // size of the name table  
int32\_t datasize; /_ size in bytes of compressed sample data _/  
uint32\_t mode; /_ flags that apply to all samples in the fsb _/  
char zero[8]; /_ ??? _/  
uint8\_t hash[16]; /_ hash??? _/  
char dummy[8]; /_ ??? \*/  
} FSOUND\_FSB\_HEADER\_FSB5;  
but I cannot get the format for fev file. Can it be public to get?

just to clean up your assumption there

#ifdef FMOD\_SUPPORT\_PRAGMAPACK  
#pragma pack(1)  
#endif  
struct FSB5\_HEADER  
{  
char id[4]; // ‘FSB5’  
unsigned int subVersion; // Extended FSB version  
int numSubSounds; // Number of subsounds in the file  
unsigned int headerChunkSizeBytes; // Size in bytes of all of the sub-sound headers including metadata  
unsigned int namesChunkSizeBytes; // Size in bytes of all the original source file names  
unsigned int dataChunkSizeBytes; // Size in bytes of compressed sample data  
FMOD\_FSB\_FORMAT dataFormat; // Compression format  
unsigned int dataFormatVersion; // Version number of compression format  
unsigned int mode; // Flags that apply to all subsounds in the FSB  
FMOD\_UINT64 compatibilityHash; // Deprecated  
FMOD\_GUID guid; // MD5 hash based unique identifier using all header information  
} FMOD\_PACKED;  
#ifdef FMOD\_SUPPORT\_PRAGMAPACK  
#pragma pack()  
#endif

My final purpose is to read the audio file path in fev file.

I did a quick google and this might help you out

I might look at an online doc for FSB5 if people are interested in it
