[Release]Portable meditation engine

looks good(I mean sounds good,lol)

i'll test this out tonight...

I've sorted the shifting for both base and frequency, although I seem to be getting some small crackles when changing the frequency of the wave. Has anyone else that has worked with audion on the PSP come across this problem, as it seems to work fine without any shifting.

I'll write up an ammended Deep Mind preset and upload the new copy in a bit.

edit: nevermind, sorted the crackling audio problem

SOunds like a placebo effect to me.

Ok, here's the new version. I'll start writing up a few more presets and add a tutorial to show you how to change across the BWG presets to PME presets. Operation is pretty much the same, boot it up, up and down select the preset, and X to start the selected preset.

Here's a description of the Deep Mind preset PME comes with:

Zitat:

---

14.1 Hz - Earth Harmonics- accelerated Healing (1min)

10 hz - Centering, sleep spindles, arousal (6min)

7.8Hz- Shumman Resonance, ESP activation (9min)

5.5Hz- Inner guidance, intuition, heat generation (3min)

4.0Hz- Astral Projection/Telepathy/Seduction mindset (10min)

3.5Hz- Wholebeing regeneration, DNA stimulation

Benefits include: Sleep reduction/accelerated learning/ESP enhancement/Telepathy/OOBE

Updates News: After researching some articles by the Monroe Institute and the Association of Lucidity, I added 3 simultaneous harmonics which greatly increases your capacity to Astral Project

WARNING: You may fall asleep rapidly. Do not use while driving

The format for the PME preset files is as follows:

Code:

---

Deep mind
V300.0 14.1
V100.0 1.6
V50.0 0.7
V50.0 0.4
T0 40 120 300.0 10
T0 240 360 300 7.8
T0 690 760 300 5.5
T0 880 960 300 4.0
T0 1360 1800 300 3.5

---

The first line is a simple description of the preset. The next 8 lines are initialising the voices with a set base frequency and binaural counterpart. If you want a voice to be silent, simply provide 0 for both. The last 5 lines in this preset setup the timing for the first voice(V0). The format for the timing function is as follows(T<voice#0-7> <start time(secs)> <end time(secs)> <base frequency to shift to> <binaural frequency to shift to>). As you can see this preset slowly lowers the main voices binaural beat from 14.1hz down to 3.5hz over a period of 30m, while keeping the base frequency at a steady 300hz.

More presets and a status bar on the way :)

wow looks pretty cool!

Are you resetting the sample data to zero when you change frequencies? That will cause pops if the previous sample was not close to zero.

I was missing the few lines that checked to see if the frequency had changed, and if it does then it changes the timing appropriately, thanks anyway :)

edit: here's my slightly modified version of the audioCallBack function from the wavegen sample in the SDK

Code:

---

void audioCallback(int channel, unsigned short* buf, unsigned int length) {
    const float sampleLength = 1.0f / sampleRate;
        const float scaleFactor = SHRT_MAX - 1.0f;
    sample_t* ubuf = (sample_t*) buf;
        int i;

        if (freq[channel] != oldFreq[channel]) {
                sampleTime[channel] *= (oldFreq[channel] / freq[channel]);
        }

        for (i = 0; i < length; i++) {
                short s = (short) (scaleFactor * sinf(2.0f * PI * freq[channel] * sampleTime[channel]));
                ubuf[i].l = s;
                ubuf[i].r = s;
                sampleTime[channel] += sampleLength;
        }
        if (sampleTime[channel] * freq[channel] > 1.0f) {
                double d;
                sampleTime[channel] = modf(sampleTime[channel] * freq[channel], &d) / freq[channel];
        }
        oldFreq[channel]=freq[channel];
}

The code that is in bold is what I was missing :)

WOW, this application is great!! :Jump: I love it, because it's nice to look at, and I think I feel weird when I listen to those presets :confused: *or googly

Edit* I just tried the new one, and when I click the Deep preset... it comes up for about 1 sec then... it stops and the psp stops functioning. Either I did something wrong or maybe I should use the older version

While it might not be the most effective method of inducing, the theory is sound and to my knowledge is measurable using an EEG, so dig out that high-priced medical equipment everyone! :)

edit: Devun, are you on a 2.0?
edit#2: seems it's crashing for me too, my last addition must of messed something up, working on it :)
edit#3: fixed, download from the same URL again and it should work :)

been using it, i like it alot, it like being in a
car or plane on a long trip, the hum of the engine
always send me off(not driving of course).

hmmmm so relaxing....

p.s talk to people with you head phones on, it distorts their voices, sound funny. lol


[edit] just to let you know, this new version has crashed on me twice in a row,
as i write this, its now three, when changing profile,
it just goes silent then turns off, i'm on 1.5, im gona go back to old version for now, hope this can be fixed.


reply to Psilocybeing - edit#3
just re-downloaded new version (of the new version) and still crashing with me
