how to play a sound file on right and left speaker ??

Hi all,

 

My goal is to try to play a sound file with .wav (format) on the left and then on the right speaker and eventually to try to play

the sound file on both speakers. I have attached the code that shows what I have done so far, I tried to extract waveform data out of "Sound File Read.vi" however I was unfortunaly unsuccessful. So I would really appreciate if you guys can provide some help with this issue.

 

Thank you

DO NOT POST BITMAPS TO THE FORUM AND DO NOT CHANGE THE NAME OF THE FILE TO GET AROUND THE BAN!!!!!!

Hi,

 

as others might want to look at that picture too I converted it to a "real" PNG file...

 

@nxb: Do you notice the shrink in filesize? Now it's just 1% of your file, but showing the exactly same content...

Best regards,
GerdW

+1 for not posting a renamed bitmap.  Bitmaps make kitty sad. Cat Sad

 

Is your sound clip a single- or multi-channel recording?  If it's a single-channel file, you'll need to control the balance some other way.

 

Other option is to take that sound and edit the audio file so you have one file that's only left channel, another that's only right, and a third that's both.

If I send an audio signal (music playing) into "Line In" port of the PC and use "Sound Input Read.vi" to read the audio data I am having difficulties to split that audio signal into individual speakers. I can hear the sound on both speakers but unfortunatelly I don't know how to edit the audio file or to split that signal so I can hear it either on right or left speaker. Any help will be greatlly appreciated.

 

Thanks,

How are you generating the signal? What is the source?

 

Could you alter the balance there, at source, and record three files - left, right, both?

Hi

 

My audio source is a cell phone that plays mp3 files. So I would connect an audio cable to my audio source and the other end of my audio cable to "Line In". I really do not have that flexibility to change the balance on my source in additon to that the goal is to be able to control the balance through LabVIEW. By the way I am using LV 8.5.

 

Thank you

But how do you change the frequencies in your codes? I am thinking if it's even makeing any sense to change the frequencies of one channel compared to another because the sound will become chaos.
