如何用zybo板（zynq-7010）上实现变声功能？

Question

网上下了soundtouch库，根据这篇文章
https://www.cnblogs.com/CodeMIRACLE/p/5514806.html
用VS编译出的exe文件效果很好，但不知如何把C++代码直接扔进板子里，用了vivado hls，出现了如下错误，现怀疑大方向就是错的？望诸位指点一二

要使用Zynq-7010上的ZYBO板实现变声功能，您需要遵循以下步骤：

1. 下载并安装必要的库和工具。这里包括soundtouch库、Vivado HLS以及Zynq-7010开发环境。

2. 编写C/C++代码以在ZYBO板上运行SoundTouch库提供的声音处理函数。

3. 将编写的代码与Zynq-7010硬件结合，使用Vivado HLS进行优化。

4. 在目标板上构建和运行您的程序。

5. 使用调试器检查和解决可能存在的问题。

具体来说，您可以按照以下步骤编写C++代码来完成这个任务：

首先，确保已经下载并安装了必要的库和工具：

wget https://github.com/soundtouch/SoundTouch/releases/download/v1.2.0/SoundTouch-1.2.0.tar.gz
tar -xzvf SoundTouch-1.2.0.tar.gz
cd SoundTouch-1.2.0/
./configure --with-soundtouch-dir=/usr/local/soundtouch
make
sudo make install

然后，创建一个名为main.cpp的新文件，并添加以下内容：

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

#define MAX_WAVE_SIZE 4096 // Maximum wave size for processing

// Function to read a file into memory
FILE *read_file(const char *filename) {
    FILE *file;
    struct stat st;
    if ((file = fopen(filename, "r")) == NULL) {
        fprintf(stderr, "Failed to open file %s\n", filename);
        exit(EXIT_FAILURE);
    }
    if (fstat(fileno(file), &st) == -1) {
        fprintf(stderr, "Failed to get file statistics\n");
        exit(EXIT_FAILURE);
    }
    return file;
}

// Function to write data to a file
void write_file(FILE *file, const void *data, size_t size) {
    fwrite(data, size, 1, file);
}

// Main function
int main() {
    // Read input audio file
    FILE *input_file = read_file("input.wav");
    
    // Process audio file using SoundTouch API
    soundtouch::AudioInfo info;
    info.sample_rate = 44100; // Sample rate
    info.channels = 2; // Number of channels
    info.format = soundtouch::kInt16; // Format
    info.bit_depth = soundtouch::kBPS16; // Bit depth
    
    // Initialize SoundTouch library
    soundtouch::InitializeLibrary();
    
    // Call SoundTouch API to process audio
    soundtouch::ProcessAudio(info, input_file, output_file);

    // Write processed audio back to file
    write_file(output_file, data, sample_size);

    // Cleanup
    soundtouch::TerminateLibrary();

    return 0;
}

请注意，上述代码只是一个基本示例，实际应用中可能会有更多细节需要考虑，例如音频格式转换、数据大小限制等。此外，您还需要确保正确设置文件路径和参数，以便将输入文件读取到内存中，并正确调用SoundTouch API来进行音频处理。
