SGC Format

struct SGC {
    SGCFile files[];
    // padding to 0x4000
    char data[]; // each file's data has padding between them to next multiple of 0x1000
}

struct SGCFile {
    char name[16];
    uint32_t sample_rate;
    uint32_t data_position; // byte offset for the file's data. The first file will have an offset of 0x4000
    uint32_t data_length;
    uint32_t channels; // Not actually sure what this is, but it's always 1, and all files are in mono :)
    uint16_t coef[16]; // DSP coefficients
