Can you help me write a C++ program that reads blocks of audio data from the microphone using the ALSA driver?

chatgpt-cpp-audio1.cpp

#include <alsa/asoundlib.h>
#include <iostream>

int main() {
  // Open the default PCM device
  snd_pcm_t *handle;
  int error = snd_pcm_open(&handle, "default", SND_PCM_STREAM_CAPTURE, 0);
  if (error < 0) {
    std::cerr << "Error opening PCM device: " << snd_strerror(error) << std::endl;
    return 1;
  }

  // Set the audio parameters
  snd_pcm_hw_params_t *params;
  snd_pcm_hw_params_alloca(&params);
  snd_pcm_hw_params_any(handle, params);
  snd_pcm_hw_params_set_access(handle, params, SND_PCM_ACCESS_RW_INTERLEAVED);
  snd_pcm_hw_params_set_format(handle, params, SND_PCM_FORMAT_S16_LE);
  snd_pcm_hw_params_set_rate_near(handle, params, 44100, 0);
  snd_pcm_hw_params_set_channels(handle, params, 2);

  // Set the audio parameters
  error = snd_pcm_hw_params(handle, params);
  if (error < 0) {
    std::cerr << "Error setting PCM parameters: " << snd_strerror(error) << std::endl;
    return 1;
  }

  // Allocate a buffer to hold the audio data
  const int bufferSize = 4096;
  short buffer[bufferSize];

  // Read audio data in a loop
  while (true) {
    // Read audio data from the microphone
    int readCount = snd_pcm_readi(handle, buffer, bufferSize);
    if (readCount < 0) {
      std::cerr << "Error reading audio data: " << snd_strerror(readCount) << std::endl;
      return 1;
    }

    // Process the audio data here...
  }

  // Close the PCM device
  snd_pcm_close(handle);

  return 0;
}

In this generated code the usage of the snd_pcm_hw_params_set_rate_near is incorrect as the function has the following declaration
int snd_pcm_hw_params_set_rate_near(snd_pcm_t*, snd_pcm_hw_params_t*, unsigned int*, int*)

ChatGPT fixed this when I asked it to add error checking https://gist.github.com/davesnowdon/34c2d661240e781a4c2c3a6f0ae982e7
