getTunerFrequency is not working at all.

Solar2D Daily Builds and Public Releases
#1

I’m working on a guitar tuner. The getTunerFrequency is returning random values if the frequency is lower than 1000. Which is a problem. For a guitar the 1st. string should be a E4 note which the range of the frequency should be around 320.244 to 339.286.
If I whistle any continuos sound the frequency returned by the function seems to be stable. But this frequencies are always above 1000. Is there an issue with lower frequencies? or there is a low pass filter applied?
I even try the SimpleTuner Corona SDK application and it does not work at all, I have similar results.

Also I tried the SimpleTuner with an electronic Yamaha keyboard and I got similar random values, an even if I always hit a C keys (C0 thru C6) the SimpleTuner app returns random values around the F# note. [import]uid: 9975 topic_id: 18986 reply_id: 318986[/import]

What build number and what platform are you seeing this problem on? The turner code is low-level code that is platform dependent. [import]uid: 7559 topic_id: 18986 reply_id: 73279[/import]

Mac OS (Simulator), iPhone and even Android (which I think the function is not supported)

I tested in the three environments and all gave me same results.
Yesterday tested on Corona SDK - Build 704, but this issue can be reproduce with at least the last 10+ builds .

Even the SimpleTuner app with a electronic Yamaha keyboard does not get any good result. C Keys are being returned as range values from F#,F , G and A [import]uid: 9975 topic_id: 18986 reply_id: 73292[/import]

I’d be interested to see if this works in the newer 8xx builds. Let us know what you discover. [import]uid: 140429 topic_id: 18986 reply_id: 113489[/import]
