    Default Funiculus Guitar Tuner v0.01 - testers needed

    Hey guys,
    I've put Funiculus Guitar Tuner, v0.01 (alpha) in the downloads section of its SourceForge project: http://sourceforge.net/projects/funiculus/ .
    To install it, just do the usual...download it, place Funiculus.app in the applications directory, and make sure the permissions are set for both the folder and the executable. (Source code is also up-to-date.)

    Because this app uses the internal microphone for pitch detection, it will only work for the iPhone and not the iPod touch. (And I've only tested it on 1.1.1 so far).

    This is a very very early version, and the pitch detection is not perfect...I plan on making a number of improvements over the next few weeks. The user-interface is not great either. The point of releasing it right now is to see how it works on other guitars...different guitars have different acoustics, etc...

    I've only tested it on one guitar so far...it has some problems detecting low E and A. But since low E will actually register well when the tuner is set to high E (on my guitar at least), I figure I can implement some algorithm to look at different octaves...if you test this, please let me know if this works for your guitar as well.

    And I imagine this a pretty energy intensive program, so don't forget about it and leave it running, or your battery will probably drain.

    Thanks,
    JLA

    Default Fantastic idea!!!

    Hi, that is just wonderful, i will teste it and let you know, i am a musician for a living, so this is really handy. If I can help with my knowledge of music theory and stuff let me know, maybe we can collaborate on a really great set of tuner apps

    PM if you like

    I just tried (on 1.1.2 & acoustic: Clarity (Ovation copy)); usage seems a bit unsettling, since those dots are a bit rough and the jumps a bit edgy... my ears didn't fully like it, but when I used my Korg GA-30 (cheap standard electric tuner) afterwards, it showed that your tuner actually lead quite close to the "truth"
    The low E was indeed a bit tricky, no problems with the A though.

    I had to get used to press the buttons at the bottom to select the string though; when tuning, I often jump between strings to also compare "by ear", and the tuners I know just recognize the chord.

    Have you though about using a pseudo-analogue needle indicator instead of the rough dots?
    That along with some value determined over a longer time (quarter or half a second or so... as an additional value... to avoid too much jumping and get an average) should let to pretty good results

    Before this sounds like too much criticism though: very good job for a 0.01!

    Default nice work...

    Best .01 release I've ever seen of anything.

    Some thoughts:

    1) I've downloaded the source from the SVN and will see what I can do to help (if anything).

    2) As a Banjo player it would be 'really' nice to not have a tuner only work for a conventionally tuned guitar. Even many guitar players use alternate tunings.

    3) My favourite tuners IRL attempt to figure out which note you are closest to then show the note and +- from true for that note. This makes for an easier time tuning any string instrument. If you can't remember what notes you are supposed to tune to then perhaps being in tune isn't going to make much difference. (I guess that's just me trying to make this useful as a Banjo player again.)

    4) It seems to be trying a little 'too hard' at the moment which makes it a bit jumpy but I've only played for a few minutes with it on my Banjo and the Piano.

    5) I agree with CCR that a pseudo analogue needle would be easier to follow and I think my comment 3 is something along the line of his as well...

    all in all very impressive! Maybe after dinner and much drinking when everyone goes home tonight I'll try to throw some code in the mix.... or maybe I'll just wake up in the morning recovering from today and do the same.

    Thanks! I know robota has a tuner as well but I think it's missing a lot and as far as I can tell although 'free' is closed source (and useless to anyone not playing in a straight guitar tuning - see - another reason to be more open with what you are tuning to!)... oh.. hey... open source = open tuning....

    Ok... maybe I need to start drinking now!

    Boing

    Boing!

    Thanks for testing this out...

    I intend for this to be a pretty open project...the more help the merrier. While the guitar is my main instrument, I also dabble in banjo and mandolin, so I will definitely incorporate these things...in a day or two, there will probably be a version that supports not only multiple instruments but multiple tunings for guitar as well.

    There are three main components of this app:
    1) the sound routines, which was a huge stumbling block in the past before a workaround was discovered.
    2) the math routines, which are involved in pitch detection (musical math people wanted)
    3) the GUI, which I threw together as fast as I possibly could from my Garf stuff.

    I've somewhat isolated these code sections from each other, so no knowledge of the others is really required. So anyone who would like to help out, please let me know.

    JLA
