HI,

Is it possible to generate tones (sounds) in DS?

For example middle C is 261.63 Hz.

Regards, ah

Yes check out the 'Audio Signal' sample

Dave,

Thanks, I was searching for music or tones or generate.

b.t.w. Slight typo on CreateSynth "ca produces" should probably be "can produce"

Regards, ah

Hi,

Supplementary Questions -

Can we send sounds to one specific ear?

Or different volume to each ear? (stereo)
And/or have a slight delay to one ear (spatial audio)?

Or the same questions for PlaySound/MediaPlayer/PlayRingTone/TextToSpeech?

Regards, ah

I would like to put on record that I don't know quite enough to categorically state that DroidScript does not do these things

old-style emoticon added to prove to myself that Google groups changes it when I type that ;-)

You can set the left and right volume on the MediaPlayer object

https://symdstools.github.io/Docs/docs/app/CreateMediaPlayer.htm#&ui-state=dialog

The new Music component has quite a lot of functionality and is a wrapper for WebAudio and you can get access to the underlying WebAudio context if required too. You can do all sorts of amazing things with WebAudio (probably everything that you need) , but it might not be straight forward to implement (that's why we wrote a wrapper for it)
