soundcard VI replacements?

[Joey Oravec]

Hi,

I was using the soundcard VIs today. Has anybody written any better
replacements for these?

In particular it is excessively slow to open a WAV file, and the sound VIs
all have 4 datatypes coming out plus the sound format parameter. I
understand that the lvsound.dll requires this, and that just using the
waveform type would drastically increase the memory footprint of a wav file.
But still there's got to be a better solution.

So anybody seen replacements which are less messy for handling soundcards
and WAV files?

joey,
I looked extensively for a better solution to these .vi's (about 2-3 months ago) and I was unsuccessful. Without LabVIEW releasing the source code for lvsound.dll, the best current solution is to write your own .dll using either winmm.dll (windows multimedia) or DirectSound (part of DirectX). I started doing the reserach on these, but I never had the time to make them.

Hope this saves you some time in looking,
