Harmonize life in accordance with the frequencies of nature
and there will be more joy, happiness and beauty
in our everyday experiences.   Edgar Cayce

432 Hz ? késako ??
Tune to 432 Hz (instead of using the pitch currently set to 440 HZ), or listen to music at the frequency 432 Hz is to be in harmony with the universe. Music based on 432 Hz transmits energy healing beneficial because it is pure and fundamental that we find in nature.
It is true that there are only 8 vibrations per second difference compared to the standard setting (440 Hz), but this small difference produces a remarkable effect on our consciousness.

The music so played and listened is softer and brighter, giving greater clarity, more harmonious sound and pleasant than the frequency 440 Hz 
432 Hz giving greater clarity than 440 Hz, there is less need to play as hard as 440 Hz This means less hearing problems, as long as you do not turn the volume too high, of course. In addition, there is also less noise pressure.

It is up to you to try ...

 To convert your music library from 440 to 432 Hz instant when listening, two other options available to us in a few clicks: 

 - Foobar   http://www.foobar2000.org/ (audio player for Windows)
 conversion in real time with the plug-in SoundTouch acropolis.lokalen.org/?download=foo_dsp_soundtouch.zip%20
Slide foo_dsp_soundtouch.dll file in the "components" folder in the installation directory of foobar.
Then go to File-> Preferences -> Playback -> DSP Manager
In the "Available DSPs" section click SoundTouch and return it (with the Up arrow) in the "Active DSPs" section
Click it again and click "Configure selected"
Select "Pitch adjust" and set the cursor to -0.32 semitones (adjusting with the arrow keys on your keyboard)

 - Vox (Mac)   http://coppertino.com/vox/?src=vox_original 
Audio player for Mac. Go to Window-> Effects: check "Pitch Shift" and bring the small down arrow to -0.3 
 Unlike Foobar, repeat this each opening drive. 

 And finally, the batch with: 
- Audacity  (Windows and Mac)
Open an audio file.
Create a script: File-> Edit Scripts-> Add
Enter the name of the new script or MP3 Conversion Conversion Flac or Wav Conversion
Then click Insert and select the command (double click) ChangePitch.
Parameters Edition:
Percentage change:  -1.818  (see the Half-tone box  -0.32 
It is enough: OK
Click again on "Insert"
 to select the desired command: ExportFlac, ExportMp3, ExportOgg or ExportWav.
For the final script and configured, you have:
ChangePitch in 01 (with  Percentage = -1.818000 )
02 Export (of your choice)
03-End-
Close all.
To convert your audio files, simply open Audacity, just follow the path: File-> Apply script files [by selecting the desired script] and Audacity will create a new folder named "cleaned" in the same directory. The Tag is respected, except the image.
 N.B. Before applying the script, simulate an export file, just to set the type and encoding options (for MP3 bitrate mainly).

and... Enjoy !
