Isochrone Beats erstellen?

[dieme]

Kann mir jemand sagen ob man mit Audacity Isochrone Beats (isochron: griech. gleich lang dauernd) erstellen kann? Isochrone Beats gelten als eine der effektivsten Methoden der Gehirnwellen-Stimulation. Sie bestehen aus extrem schnell hintereinander abgespielten Tönen gleicher Stärke.
Will man zum Beispiel Gehirnwellen im Theta-Frequenzbereich von 5 Hz erzeugen, wird der Ton fünfmal in der Sekunde mit fünf entsprechend langen Pausen abgespielt. Das menschlichen Gehirn geht in Resonanz und bildet die entsprechend gewünschte (hier 5 Hz-) Gehirnwelle. Oder welches Programm wäre möglicherweise dafür geeignet? DANKE

Can someone tell me whether you can create isochronous beats (isochronous: Greek for equal length) with Audacity? Isochronous beats are considered to be one of the most effective methods of brainwave stimulation. They consist of tones of the same strength played extremely quickly one after the other.
For example, if you want to generate brain waves in the theta frequency range of 5 Hz, the sound is played five times a second with five correspondingly long pauses. The human brain goes into resonance and forms the desired (here 5 Hz) brain wave. Or which program might be suitable for this? THANKS

OK, I’m thinking you might be able to use Steve’s Envelope Follower to create these “tones”.

The idea is to create a 5Hz control-signal and “multiply” it by your music file. Try these steps:

• 1. In a “new” audacity workspace, Generate > Tone > Sine a 2.5Hz tone of, say, 10 seconds. Note there are 5 peaks per second. This will be your “control” signal.
     
     
     
• 2. Deselect the newly created track by clicking elsewhere in the track area. (The first track will gray out)
     
     
     
• 3. Create a second track, Generate > Tone > Sine, a 440Hz tone. This will be our audio track.
     
     
     
• 4. Select All tracks, by hitting “Ctrl-A”. We do this to pass both tracks to the envelope follower.
     
     
     
• 5. Go to this link: How to capture envelope from one track and apply to another - #3 by steve and in the white “Code” box, click “Select All”, then Ctrl-C, to copy the envelope follower code to the Windows clipboard.
     
     
     
• 6. Back in Audacity, select Tools > Nyquist Prompt, then Ctrl-V to paste in the envelope follower.
     
     
     
• 7. Click OK, then set .01 as your Time Resolution, keep Peak, then OK. This will apply the envelope follower to your second track.
     
     
     
• 8. Click “Solo” in your second track and play the track.

I hope this helps.

There’s an app for that / Dafür gibt es eine App …

Das war eine sehr ausführliche Antwort. Ich werde es gleich ausprobieren. Vielen Dank vorab.
