I may have had such a program on one of my older machines, that is no longer operating, but it would have been on an older OS anyway.
I can plug a mic into my box, and would like to see a visual display that would register the sound of each string so as to guide me in tuning it well. (I am not so precise in my judgement of pitch that I can tell when I'm right on the note.)
I own a device that does this, but I don't have it handy, and it might need battery replacement when I find it.
I tried a search engine, but it has gotten so complicated lately--without a recommendation from a reputable screener of programs, I am afraid to get malware. And, the tuning aids that just play the note for you aren't much help to me. If my sense of pitch was good, I would just tune the strings relative to each other for my own playing and singing.
Leigh, do you have a recommendation, or even a link? You're one guitarist I remember in our group. I remember JL had a group, but I don't remember if he played six-string guitar.
I only ever tuned one string, on my old 12-string Strat.
I could tune all the others, from that.
Buy a gizmo that clips on the head. Cheap enough.
I downloaded a Windows app to install, and it told me that, after installation, an icon would appear on the desktop. When it didn't happen immediately, I tried restarting the computer--no icon on the desktop. Since I am supposed to start the program from the icon on the desktop, it doesn't look promising, at this point.
Unless it has installed the icon in the start menu
FWIW your tuner, and fresh batteries should ALWAYS reside with your guitar, or musical equipment. NEVER start playing without tuning up FIRST!.
As far as computer programs are concerned, I've never used one. I started out years ago with a tuning fork, which I still possess, and have had electronic tuners for, at least the last 30 years.
As far as where I keep my tuners is concerned. As I use 4 different guitars (Acoustic - Electric -12 String -Bass) I have a briefcase purely for my requirements. In it reside, tuners, leads, spare strings, spare batteries, Straps, a basic tool kit, a power board (and extension cord) along with any pedals that I might need and my music (now on a tablet, but used to be two absolutely chokkas folders). Fortunately I don't move around too much, or I'd also be lugging an amplifier, too. I have one amp at church, and one at home.
I worked it through, myself.
I tried to install some programs, which did not work.
When I ran the installation program to install one of the programs on CNET, the promised desktop icon that was supposed to be the means to run the program for me did not appear, even after I restarted my Windows 8.1.
A couple of other programs were designed for Apple's OS or for Android.
I could not get Guitar Guru, hosted at Softpedia, to work. MacAfee and Avast each warned me that some malware is sometimes found on Softpedia downloads.
The program that finally installed and worked for me is something called "Audio Tuner."
But, I did not get the guitar properly tuned, because I broke the High E string.
Now, I'm thinking I had best remove the other tuning program files, while I can remember which ones fell short. Otherwise, I might well find myself clicking on "set-up" or unpacking zip files to programs I don't want.
I managed to tune my back-pack guitar and refreshed my memory on some chords. I got the tabulature for "What a Friend We Have in Jesus" and played
it for Ruby.
I have fond memories of playing that for a room full of developmentally-disabled people when I was leading a group devotion. I learned that, by chance, I had picked perhaps the only hymn that the group knew (perhaps they sang it every day, or every week). It was great fun, to have dozens of them singing along (usually, they listen to the hymns as performed).
NEVER start playing without tuning up FIRST!. - Does not mean tuning it up the night before, or even before you leave home. It means tuning it up at the venue immediately before you start playing.
