AW: vrf (VRF) Making an audio file -

Question asked by VRFuser on Jun 6, 2008
Hello,
you dont need the "" around the parameter C:     emp     est2.wav. Then it works.
The txt-object is already text so no "" is needed.
best regards
Jochen

I may be a complete novice with Matlab, but I can’t immediately see why this doesn’t work ?

Halts w/ rather unhelpful message.

VEE Pro 8.01

How about using wavwrite function in matlab?

 

here's clip from docs.

 


wavwrite - Write Microsoft WAVE (.wav) sound file


Syntax


wavwrite(y,filename)
wavwrite(y,Fs,filename)
wavwrite(y,Fs,N,filename)


Description


wavwrite writes data to 8-, 16-, 24-, and 32-bit .wav files.

wavwrite(y,filename) writes the data stored in the variable y to a WAVE file called filename. The filename input is a string enclosed in single quotes. The data has a sample rate of 8000 Hz and is assumed to be 16-bit. Each column of the data represents a separate channel. Therefore, stereo data should be specified as a matrix with two columns. Amplitude values outside the range [-1,+1] are clipped prior to writing.

wavwrite(y,Fs,filename) writes the data stored in the variable y to a WAVE file called filename. The data has a sample rate of Fs Hz and is assumed to be 16-bit. Amplitude values outside the range [-1,+1] are clipped prior to writing.

wavwrite(y,Fs,N,filename) writes the data stored in the variable y to a WAVE file called filename. The data has a sample rate of Fs Hz and is N-bit, where N is 8, 16, 24, or 32. For N < 32, amplitude values outside the range [-1,+1] are clipped.

I don't do any work with this kind of stuff but here's my thoughts.  Going from memory (an increasingly bad idea as the years advance), the WAV file format is pretty simple - it has a header and then bytes giving a timesliced i.e. sampled representation of audio amplitude, no compression or anything.  There are plenty of descriptions of the WAV file spec on the web.  I reckon it would be easy to write a VEE program to write a WAV file to produce a simple signal.  The files could easily get really big though.
