Re: [Discuss-gnuradio] Audio sink + windows binaries

Great Geof,

thanks for the feedback!

The wav file was downloaded from the internet and the data file was generated by the simple matlab script that is also present in the 
Dropbox directory I provided: essentially it opens the wav file, reads the samples, extracts only one of the two channels and saves the data in float32 format.

Just to clarify: both files (data and wav) are played perfectly OK on my Linux Box, so the issue is not with wav vs data but with Linux vs Windows.

thanks again,
Achilleas

Achilleas,

I have duplicated the problem with the same setup, playing the .data file w/ the file source, and also playing the wav file with the wav file source produces similar distorted results.

However, I don't have a quick solution to return.  I'll need to keep looking.

Can you describe how you created the .data file and .wav files?

Geof

Hi Marcus,

thanks for offering to help.

As i say in my email the audio file sounds with a different speed than the original!

I have added a new file in the Dropbox link that I sent last time, 
"experiment.m4a"
If you play it you'll hear the two different sounds: one from my standard wav player and the other from within grc.

thanks again,
Achilleas
