continuous sound buffer

[huguerreiro]

Hello,

I'm trying to  create a FIFO buffer of a sound continuous acquired by PC microphone, to future generate a trigger and a perform a analysis of an specific range of samples.

I'm already acquiring the sound, generate the trigger and recording some samples, but the duration of the recorded sound it's never the same.

Thanks

Hi,

You are running your VIs one a non-deterministic operating system, by the way when running your application several times you might encounter some "big" jitter.

I would consider using a timed loop and using its options to check if the time elapsed was the one you expected.

Have a nice day !

In this application, the timing is determined by how many samples you read each time from the sound card. You pull data from the sound card very .5 second. So instead of using time elapsed, you just count how many loops that has elapsed.
