Hello, I am working on code that will read a waveform of a sound pressure measurement and calculate the octave band levels. I would be incredibly grateful if someone could take a glance at my code to see what I have wired incorrectly... The issue I think I'm having: The output of the "Basic Averaged DC-RMS" output wont index when I put it into the for loop. I tried to get around this problem by building arrays for each RMS output and then indexing into the for loop. Doing this doesn't allow me to graph the output... Any ideas as to why the "Basic Averaged DC-RMS" wont index directly?
I'm working on a project that requires sound output via the Windows audio subsystem, and so I've recently found myself using the LabVIEW "Sound" pallet vi's for the first time in.....well...ever! The sound output ("Play") vi's allow you to setup and configure an output "task". As part of that configuration, you define a buffer size. Once that sound output task is configured, you effectively write your sound samples into this buffer over time, periodically refreshing this buffer with new audio sample data. That's all fine and good, but unfortunately it seems like there is no mechanism
Hi All! Since LabVIEW uses only Windows MME driver for sound in and out, I'm looking for an other way to get sound data into LabVIEW with much less latency. Has someone use ASIO4ALL for audio input? For sound out I use Midi via MME and the Windows own synthesizer. Its latency is really not high. But the input data comes with some hundred milliseconds lateness. With MME: I tested on 2 systems. About 350ms latency and not really depending of the system load. I tried also with small sample packages of 600 and 1200 byte/chn and a sound card acquisition rate of 96kS/s. In order to c
