hello,
in bioexplorer i created a design where you can hear piano music with the volume dependend on the amplitude of the two trained frequencies.
i use two audioplayers because i made two audiofiles, one for the right hand and one for the left hand (melody) of the piano piece. you can train two frequencies at once, when both are going in the desired direction you hear both hands playing together. if only one is in the desired range you only here one hand playing. both audioplayers are synched and playing all the time, the volume between 0% and 100%.
i like this kind of feedback because it is very pleasurable and simple. is this possible in bioera?

thanks,
michael

Yes, that should be possible. You can have multiple PCMAudioPlayer elements. It is possible to read audio file with several elements like SoundFileReader. And it is possible to modulate the amplitude in several ways, for example using ExpressionEvaluator and using the second input as amplitude modulator.

There is also Generator for pure sine tones (with options for modulate amplitude and/or frequency) and MIDI.

thanks jarek for the quick answer.
that sounds great.
