A while back I played a video game with a character who spoke entirely in auto-tune (Warning: link is NNSFW: Not necessarily safe for work). I thought it was a really fun idea and have been trying to replicate it in real life with varying degrees of success.
I tried various programs and apps like Tune-Me or I-am-T-Pain, but nearly all of them require the user to record an audio snippet, process the audio then play it back. This batch processing approach takes far too long and is cumbersome considering how much auto-tuning I plan to do.
My best attempt so far used an android app called Voloco to produce auto-tune without needing to process the audio in batches. It works well, but there's a very noticable delay (~.5 seconds). In practice this makes it nearly unusable because my voice isn't synced with the auto-tuned output. Anyone nearby can hear my spoken voice separate from the auto-tune and it comes out like 2 people talking over each other (or rather one person singing over another).
My plan is to have a battery-powered speaker hooked up to my phone which is hooked up to microphone. I will have the phone somewhere away from my mouth (maybe in my pocket), the microphone next to my mouth or pinned on my shirt collar and the speaker(s) either mounted on my shoulders or in a backpack. I've got everything working so far, but I need to mute myself from people who could be standing as close as 5 ft from me without preventing the microphone from picking up on my voice.
This is my plan, but I welcome any advice or alternatives. If someone has a way to achieve real-time auto-tune without all this I'm happy to take a look.
I want to use to speak to people close to me (5ft - 15ft), not auditoriums or across yards.
I need to be able to carry the entire setup on my person. I'm willing to use a backpack if necessary, but I'd much prefer a solution that could be stored entirely in my pocket(s)
Even though it will be disorienting, I don't mind hearing my own spoken voice as well as the auto-tune. I really only care about the people around me.
My only other restrictions are that I don't want to spend a lot of money (<50$) and that I'm not really capable of doing any tricky electronics. I can may be solder something without electrocuting myself, but passed that I'd need to get a professional.
If there are any other questions leave a comment and I'll update the list. Thanks in advance.
