实时录播延迟长达100ms
请问rk3308如何降低延迟，我现在测试得出的延迟达到了100ms，项目要求在10ms以内。arecord -D hw:0,0 --period-size=192 --buffer-size=384 -r 48000 -c 2 -f S16_LE -t raw | aplay -D hw:7,0 -t raw --period-size=192 --buffer-size=384 -r 48000 -c 2 -f S16_LE，示波器抓到的波形显示延迟达到了100ms。附件是开机信息。 开机信息在这贴一下，没想到附件下载会丢经验。。。U-Boot TPL 2017.09-g88aebe4 V1.24

延迟指的是?
用麦克风录音，然后再从喇叭播放出来，这里的延迟指声音信号从喇叭进去到从喇叭出来的时间，简单的说就是示波器抓波，我说123，和录音再拨出来的123的时间差。 Livvol 发表于 2019-3-27 16:25

你试下将这两个--period-size=192 --buffer-size=384设置大一些
定位到问题点了，录播设备保持一致就没问题了，话说这个是什么原因呢？ dma buff太小了，每次传输也小，导致传输速度变慢 飞神 发表于 2019-3-28 19:38
dma buff太小了，每次传输也小，导致传输速度变慢
period-size越大中断间隔越大，延迟肯定越长。buffer越大越不易发生xrun，但延迟也会相应的增大。 wjyfirefly 发表于 2019-3-29 14:38
period-size越大中断间隔越大，延迟肯定越长。buffer越大越不易发生xrun，但延迟也会相应的增大。
period-size越大中断间隔越大，这个结论怕是不能成立。
