Voltage samples to RIFF file (*.wav)

[Coy]

I am using a DAQCard-6024E to sample two analogue audio signals (two channels simultaneously).

When sampling the signals, I get a two dimensional array of doubles ( double[,] ) containing the samples from both channels. No problems here.

I am sampling with 44k in 12 bits (on each channel).

My questions are:

- Since I want to store the data in the well-known RIFF file format, how do I get this array of samples converted into RIFF file format? (Create a .wav file from the samples)
- Do I need to convert from 12 to 16 bit? How?
- Does anyone know of examples covering this subject?


Thanks a lot 😉

Hi,

Following link will explain how to do this, if you are programming in LabVIEW?

I’m using measurement studio / c#. After having giving it a good long thought I figured out a way to do it. Thanks anyway 😉
