是否有一个函数可以返回 FluidSynth 中声音字体文件中所有乐器（预设名称）的列表或至少每个音库中的预设数量？

我能够使用流体合成器获得乐器名称和库。您要发送的命令是“inst 1”（获取位置 1 中加载的 soundfont 的所有乐器）。

$ echo "inst 1" | fluidsynth /path/to/FluidR3_GM.sf2

这不完全是“非迭代的”，但它是我能找到的获取 soundfont 文件中所有预设列表的唯一方法。

fluid_preset_t* preset = new fluid_preset_t();

// Reset the iteration
sf->iteration_start(sf);

// Go through all the presets within the soundfont
int more = 1;
while (more) {
    more = sf->iteration_next(sf, preset); // Will return 0 if no more soundfonts left
    if (more) {
        // Get preset name
        char* presetname = preset->get_name(preset);
        int banknum = preset->get_banknum(preset);
        int num = preset->get_num(preset);

        // Do something with the presetname, bank number and program number
        // Such as add it to some list so that you can refer to it later
    }
}

... 其中 sf 是 soundfont 对象。

在浏览http://fluidsynth.sourceforge.net/api/index.html的 API 文档时发现了这一点。请注意顶部的菜单，其中包含指向数据结构、文件等的链接。

I tried this:

static void inspectsoundfont()
{
    fluid_sfont_t* sfont = fluid_synth_get_sfont_by_id(synth, font_id);

    for (int bank = 0; bank < 16384; bank++)
    {
        for (int num = 0; num < 128; num++)
        {
             fluid_preset_t* preset = fluid_sfont_get_preset(sfont, bank, num);
             if (preset == nullptr)
                  continue;
             const char* name = fluid_preset_get_name(preset);
             std::cout << "bank: " << bank << " index: " << num << " " << name << std::endl;
        }
    }
}

synth is the synthesiser object, and font_id is from fluid_synth_sfload. Gave me a list of banks and preset names.
