如何设置mp3解码数据，指定采样率为24000

Describe the solution you'd like

通过配置，设置采样率。还是需要引入其他库将44100采样率数据转换为24000.
想要输出24000采样率，单声道数据

Additional context

// 配置并初始化MP3解码器
mp3_decoder_cfg_t mp3_cfg = DEFAULT_MP3_DECODER_CONFIG();
mp3_decoder = mp3_decoder_init(&mp3_cfg);
if (!mp3_decoder) {
    ESP_LOGE(TAG, "Failed to initialize mp3 decoder");
    cleanup();
    return ESP_FAIL;
}

audio_pipeline_register(pipeline, http_stream_reader, "http");    // 注册元素到管道
audio_pipeline_register(pipeline, mp3_decoder, "mp3");
const char* link_tags[2] = {"http", "mp3"};    // 连接元素
audio_pipeline_link(pipeline, &link_tags[0], 2);
esp_err_t err = audio_element_set_uri(http_stream_reader, url.c_str());    // 设置数据源
if (err != ESP_OK) {
    ESP_LOGE(TAG, "Failed to set URI: %s", url.c_str());
    cleanup();
    return err;
}

// 设置自定义数据接收器
audio_element_set_write_cb(mp3_decoder, pcm_data_receiver, NULL);

@LYL114 音源是24K采样率，还是MP3希望解码完输出24K的？

http获取的音源是44100采样率,希望解码完输出24000.自定义数据接收器接收到24000的数据。
