can i use 128 as framesize when using model , if not, how can I do it ?

我可以在使用模型的时候使用帧长度为128吗，我看现有的模型是使用的帧长度是160。如果在使用模型的时候使用128帧长不合适，那么需要改网络训练的帧长，重新训练吗？

you can use any framesize you want, set it in denoise.c macro definition

ok thanks，I read a blog that helped me，this is the address https://codeantenna.com/a/pEQArF4zmR

when modifing the frame_size to 128, should i modify eband5ms array as same time?
for example:
/for 16K speech frame_size 160 files/ // hz[i]/4*(sample_rate/win_len) = hz[i]/200
// static const opus_int16 eband5ms[] = {
///0 200 400 600 800 1k 1.2 1.4 1.6 2k 2.4 2.8 3.2 4k 4.8 5.6 6.8 8k 9.6 12k 15.6 20k/
// 0, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 16, 20, 24, 28, 34, 40, 48, 60, 78, 100
//};

/for 16K speech frame_size 128 files/ // hz[i]/4*(sample_rate/win_len) = hz[i]/250 向下取整
static const opus_int16 eband5ms[] = {
/0 200 400 600 800 1k 1.2 1.4 1.6 2k 2.4 2.8 3.2 4k 4.8 5.6 6.8 8k 9.6 12k 15.6 20k/
0, 0, 1, 2, 3, 4, 4, 5, 6, 8, 9, 11, 12, 16, 19, 22, 27, 32, 38, 48, 62, 80
};

I round up when I calculate，is this right？Frequency range for boys is 100-200hz，girl is 200-350Hz，will this have a detrimental effect？

no need actually, but you can do it as a experimentt.
