About UDA1341 Record and Playing?

文章cubbercn 發表於 週三 11月 15, 2006 11:24 pm

不知道简体字是否在这儿行得通?
Hello, my guys,
I have done an experiment using s3c2410 and uda1341st, but I have found the voice I had recorded was slower than the normal speed when playing. I set the IISPSR(5<<5)|(5<<0) which means 50.7M/(5+1),but many changes on this register don't work. I chose the 256fs, anyone have done these similar work can give me some advices? Thank you in advance:-)

You should check 2410 IIS clock and DMA related setting at first.

Are you sure 2410 can support 256FS clock rate??

yes, I am sure 2410 can support the 256s, but now I have solved the problem by setting the IIS, and UDA1341st on 384fs(50.7MHz->16.9MHz->44.1KHz).
But it seems that there is no need to use the 16bits to sample the voice,8bits is enough??

Accordingmy experiences the 8bits is enough to voice recognized when UDA1341 AGC is enable. But for best recording sound quality I suggest you set it to 16 bits mode that will get the sound more clear.
