嗯。正在求证。
原patch中关于FIR_FILTER那段:
- +#define FIR_FILTER
- +
- +#ifdef FIR_FILTER
- +#if 0
- +static const int fir_filter[5] = { 0x80, 0x00, 0x00, 0x00, 0x80 }; /* only used for debugging */
- +#else
- +static const int fir_filter[5] = { 0x10, 0x40, 0x70, 0x40, 0x10 };
- +#endif
- +
- +#else /* !FIR_FILTER */
复制代码
sunmoon1997的patch:
- +static const int fir_filter[5] = { 0x15, 0x3f, 0x55, 0x3f, 0x15 };
复制代码
尝试过改成:
- +static const int fir_filter[5] = { 0x1C, 0x38, 0x55, 0x38, 0x1C };
复制代码
效果不明显。 |
