javascript - Web Audio: No sound in right channel -

i'm trying create custom panning command using web sound api, can't sound come out of right channel using channel splitter , merger nodes:

var context = new webkitaudiocontext(), destination = context.destination, osc = context.createoscillator(), gainl = context.creategainnode(), gainr = context.creategainnode(), splitter = context.createchannelsplitter(2), merger = context.createchannelmerger(2); osc.frequency.value = 500; osc.connect(splitter); splitter.connect(gainl, 0); splitter.connect(gainr, 1); gainl.connect(merger, 0, 0); gainr.connect(merger, 0, 1); osc.noteon(0); gainl.gain.value = 0.1; gainr.gain.value = 0.5; osc.noteoff(2); merger.connect(destination);

am missing obvious here? there's jsbin preview of above code here: http://jsbin.com/ayijoy/1/

i'm running chrome v24.0.1312.57, in case that's of use.

my best guess happens because oscillator outputs mono signal. seek using stereo source , should have more luck.

edit: here's how can pan "mono" signal (bypass splitter, since there no stereo signal split, , connect oscillator straight 2 gains. connect 2 mono signals merger after adjusting gain each channel) http://jsbin.com/ayijoy/16/

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
