C语言读取wav音频例子

你好！以下是一份C语言读取wav音频的例子：

#include<stdio.h>
#include<stdlib.h>
#include<string.h>

struct WavHeader {
    char chunkId[4];
    int chunkSize;
    char format[4];
    char subchunk1Id[4];
    int subchunk1Size;
    short audioFormat;
    short numChannels;
    int sampleRate;
    int byteRate;
    short blockAlign;
    short bitsPerSample;
    char subchunk2Id[4];
    int subchunk2Size;
};

int main() {
    FILE *pFile = fopen("test.wav", "rb");
    if(pFile == NULL) {
        printf("Open file fail.");
        return -1;
    }

    struct WavHeader wavHeader;
    fread(&wavHeader, sizeof(struct WavHeader), 1, pFile);

    printf("Chunk ID: %s\n", wavHeader.chunkId);
    printf("Chunk Size: %d\n", wavHeader.chunkSize);
    printf("Format: %s\n", wavHeader.format);
    printf("Subchunk 1 ID: %s\n", wavHeader.subchunk1Id);
    printf("Subchunk 1 Size: %d\n", wavHeader.subchunk1Size);
    printf("Audio Format: %d\n", wavHeader.audioFormat);
    printf("Num Channels: %d\n", wavHeader.numChannels);
    printf("Sample Rate: %d\n", wavHeader.sampleRate);
    printf("Byte Rate: %d\n", wavHeader.byteRate);
    printf("Block Align: %d\n", wavHeader.blockAlign);
    printf("Bits Per Sample: %d\n", wavHeader.bitsPerSample);
    printf("Subchunk 2 ID: %s\n", wavHeader.subchunk2Id);
    printf("Subchunk 2 Size: %d\n", wavHeader.subchunk2Size);

    int dataSize = wavHeader.subchunk2Size;
    char *pDataBuf = (char*)malloc(sizeof(char)*dataSize);
    fread(pDataBuf, dataSize, 1, pFile);

    fclose(pFile);

    return 0;
}

这是一个基础的读取wav格式音频的例子，首先使用FILE结构体打开音频文件，然后读取WAV头部信息并打印出来，最后读取音频数据保存到缓冲区中。当然还需要更多的处理才能对读取的音频数据进行操作。希望对你有所帮助！
