Nevermind- figured out the problem. Ass clowns at Espec have wired their unit assuming the RS-232 cable the user is using is a STRAIGHT THRU cable, not NULL. This is very unususual when it comes to...

Real time audio and queues
Hi all,I have a problem with my project. I need to acquire sound from my soundcard (16 bit, 22050Hz) for later processing. I´m using a queue with consumer-producer structure. The thing is that I need...
View ArticleRe: Real time audio and queues
Hi. I dont have any experience with these vi's but I am guessing the 1ms waits may be the problem. Take them out of both loops. The top loop will then be timed by the sound acquisition and the bottom...

is your problem has been resolved by changing the value of dt ? what are setting you made in the play waveform vi parameters settings ?

You could write to a local folder that is shared using google drive, and all other locations will update eventually. No code needed.

@TC,you missed the 3 second delay- don't sweat it too much! but, there is a HUGE difference between sample clocks and samples acquired:smileywink: I really do recommend reading the help file it is...
View ArticleRe: Real time audio and queues
OK, as the wait is only 1mS and the sample rate is 20mS and there is no dataflow between the aquire vi and the wait(ms) the wait will not have an affect on the timing. Unless the sound input dll is...

Thank you for your quick answers. I have changed the timer values and now the flow is constant but the retardation in the consumer loop is too long for this real time project.
