Hi

I am new to the forum and was wondering is there any way to code an audio interface device to output to the iphone?

I am using a line 6 sonic port and an iRig(Ive used it with amplitube and found it very hissy)for input and an iphone 4 iOS ver 6.1

I am trying to code a guitar tuner app that takes the input from these devices

Any help is appreciated
Thanks

I am going to use a mic in instead of the 30pin connection

Any suggestions on using this setup?

You could use something like the iRig that plugs into the 30-pin port instead (to avoid the hiss), or get a better plug than the iRig. I would suggest searching online.

If you have one of those Analog-to-USB mixers (1 to 4 ports), you could connect it to your iPhone 4 using a 30-pin to USB adapter and it will let you record up to 4 lines in GarageBand (I have tested it in an iPad 3 a while back).

Whatever you decide to get, get it locally in case you need to return it.

----------

BTW, the hiss noise could be caused by bad grounding (or ground loop) of your guitar, Amplifier or Effects Processor (if using it).

thanks amazing iceman

I want to code a guitar tuner I have a basic guitar tuner app that plays the E A D G B and e notes but how would you go about getting an input signal to equal 440HZ

and whats the best way to program it, allow it to be within a range so A would have 435 to 445HZ

I am new to programming but Im really interested in getting something working as a summer project
