I am currently seeking a programmer, or a program, that will allow the conversion of High-Res EEG data into 1024-bit sound. I would like to augment the actual real-time data into some sound files that are audible.I have no program to take the Raw EEG data and convert this High-Res data into something that I can work with. I have got the EmotivPro license, with SDK Developer credentials; this is where my data is coming from. I did this so that I can acquire the high resolution data that my work requires.

How can I retain the hi-fi data in my transposition of low frequency brainwave data into higher pitched tones?

Greg, hi.

Question on your terminology. “1024-bit sound”. I’m not familiar with this. Did you intend to say 24 bit sound? There are PCM standards for 8, 16, 24, and I guess 20 bit formats as well.

> **[Pulse-code modulation | Standard sampling precision and rates](https://en.wikipedia.org/wiki/Pulse-code_modulation#Standard_sampling_precision_and_rates)**
>
> Common sample depths for LPCM are 8, 16, 20 or 24 bits per sample.
> LPCM encodes a single sound channel. Support for multichannel audio depends on file format and relies on synchronization of multiple LPCM streams. While two channels (stereo) is the most common format, systems can support up to 8 audio channels (7.1 surround) or more.
> Common sampling frequencies are 48 kHz as used with DVD format videos, or 44.1 kHz as used in Compact discs. Sampling frequencies of 96 kHz or 192 kHz can be used ...

A 10 bit sample value has 1024 possible values, more generally expressed as signed value -512 to +512. The original Emotiv EPOC used 14 bit samples, truncated from the original 16.

As far as a good conversion utility, have you considered the free audio app, ‘Audacity’? It can do many transforms with audio formats.

There are various utility programs that can convert data files into WAV format, a common audio file interchange format.

That is good stuff! That is what I meant. I have been seeking the most detailed version of this data, and I was thinking that the 1024-bit is the 1024 samples per second (\<1ms/).

I think that I should just wait to get the epoch. I have got zero experience with this, and I need the changes in frequency within the sound to be in step with EVERY SINGLE detail within the EEG data. I have Audacity already, does this sound like something that I have just not seen yet? I only thought that my options were with sine waves here.

Thanks for your knowledge and input.

Emotiv sample rate is only 128 or 256 Hz, configurable.

There are multiple ways of doing EEG sonification. Generally just translating the 1-40 Hz EEG by a multiplier (for example 100), so the resulting range is from 100 Hz to 4000 Hz – is not a common or very useful sonification technique.

It depends more on your sonification goals, and what you are trying detect or uncover in the EEG signal.

Sonification.That is a great term. You have been a huge help.

Do you know anything about binaural beats?
