Write BEEP to MP3?

[nullschrittx]

I was wondering if there was some way to capure the output of the BEEP function and write it to an audio file, much like can be done with TTS?

Or if there is a way to create an audio stream and write a beep at the desired frequency to a file?

The reason I ask is because I want to create a series of audio files that have different frequencies in each(left and right audio channel) above the hearing range to create an effect of wakefulness.

And I want to test multipule frequency combinations.

But on topic, is what I am trying to do possible in autoit? (I'm sure it is, I just have no idea where I would begin)

Thanks!

PS: I can edit the frequencies into their respective channels with audio software, I just need to make the audio files for each frequency.

; this can be read from a file
Global $beep_A[10][2] = [[37, 100],[50, 100],[70, 100],[90, 100],[110, 100],[130, 100],[150, 100],[180, 100],[210, 100],[100, 2000]]
For $i = 0 To UBound($beep_A) - 1
Beep($beep_A[$i][0], $beep_A[$i][1])
Next

The best AutoIt can do in the music department is probably BASS:

While I appreciate your contribution it appears you did not understand my inquiry.

I need to create an actual audio file, a real audio file, that I can open in a audio editing application. Each file being a "beep" at a specified frequency.

Basically rather than hearing the beep, I want to write the output to an audio file.

I'm taking a look into it, perhaps this library can provide me with a way to directly output two different frequency beeps to the left and right audio channel.

Although there seems to be a lot to look through.

If if helps explain what I am trying to do, the basis of the idea is binueral beats. A different frequency to the left and right ear,only I wish to consistantly swap frequencies to keep the brain stimulated, to promote wakefulness.

I don't think the beep goes through the sound card, thus you cannot capture it. You could try generating your own tone using a program like Audacity (freeware).

That is unfortunate, as it will be a pain in the ass, although I suppose once I figure out how I could just automate it using autoit, while it's not optimal, it will work.

According to this MSDN article, the Beep function doesn't work on Vista or WinXP x64, but does on Windows 7. On Windows 7 it now sends the tone through the soundcard although there's an annoying click at the end of the sound.

So the, because I am on windows 7 there should be some way to capture the sound?

You might try this thread and see if it works, I've never used it myself, but the BASS UDF is a really nice set of audio utilities.

Maybe this will give you some hints about creating sound data in code: http://www.autoit.de/index.php?page=Thread&postID=219995
