Homebrew StringTunerDS

[twimbo]

Hi to all!

I would like to present to you StringTunerDS, a homebrew for tuning guitar and bass and detect the pith of a generic sound.

It can work in autodetect mode or it can be setted to detect a target frequence. It can also generate a tone for the choosen frequence.

I think it is a pretty gadget, not only useful for instruments tuning but also to play with sound pitch detection... try it!

You will find further information and download the program and the sources at

StringTunerDS at www.object65.it

Bye

This would be so awesome if they could use this to tune Orchestra instruments like the Cello. (Yes, I play the Cello and I'm good at it

)

hey cool idea, will definitely check this out!

Try it and let me know! You can set note and octave as target... I try it with a synth and works for many instruments.

Bye

This is pretty amazing, Love the way it hears and tells if it's tuned or not.

I knew this would be made one day. Good job

OMG! my Dream Homebrew!

Thank you very much dude!

This is one of the most useful homebrew apps I've come across! I knew tuning was possible after seeing the pitch detection in Band bros DX... but this is pretty amazing.

I hope to see it updated!
Some tips about the most optimal distance from the DS and positioning would be a great help!

YESSS!!!! A fellow orch dork! I knew I'd find on one this board someday. =]

I play the viola. And quite well, too. 1st chair All County!

Anyway... THANKS for this! I needed to tune precisely; even though I have a good ear, sometimes I get off by not thinking music for a long time.

Wow, this is a great idea. I'm surprised it hasn't been done yet.

I will definitely check it out since my tuner is running out of batteries.

This is awesome - thanks!

Very handy considering I lost my old tuner recently...

Man THANK you very much....My stringtuner just died on me few days ago..And, now I found out about this...I don't know how I missed it...

Great....will be using this..

Yeah..my teacher said I should try out for all state cause he knew I was definitely good enough (I'm 2nd chair only because 1st Chair happens to be a Senior while I'm a Junior

)..but I'm too lazy to try out

Nice, I bet this will come in handy if I ever find the time to restring my guitar

Curious if the DS' built in mic is good enough for it though...

Curious if the DS' built in mic is good enough for it though...

At the beginning of the project I spent some time to investigate about DS mic... then I found some interesting settings in DSOrganize about sample resolution (now 12 bit) and amp gain. I had a problem starting and stopping samplig very fast using standard DevKitPro sampling routines but I solved it letting the sampling always on (I had strange 'rumors' that fake pitch detection algorithm). I don't know if mic can be handled better because mic is a DS area not too covered by homebrews.
Actually the only limit of the mic that I found is a not so good sensibility so you have to put the DS near to the guitar to obtain best results (look at the signal level indicator - I don't know if it is a DS limitation or only a lack of specifications! - ), also because the guitar waveform has a rapid decay.

Investigations continue... bye

Interesting findings! The only game I know of that uses pitch detection is BBDX, and they I think advise you to be a few inches away from the mic.
