I like to create problems for myself...

I have been trying to get my music and video to sync to the music. I have spent plenty of time sequencing and now that I have 1/3 o my lights up, I wanted to test them out. I used my iPod nano with headphones set to 99.1FM and EDM transmitter for sound. The lights seem to be coming on half a second or more early. After many hours of trying to figure out how I was this far off or why my computer was delaying the sound, it turns out the problem was my simple radio. (By hours, I am referring to three days)

The iPod nano has a digital audio recorder built in so you can record or replay radio. Turns out there is a delay before you hear the recording in progress. I figured it out when the neighbor drove by and asked what I was doing. I told her to tune 99.1FM and the lights were perfect!

Thanks technology!

is it just the ipod nano that is delayed
Yes. There was no problem with the timing. Sounds great in the car and on the pocket radio I picked up yesterday at Dollar General for $3.

I have speakers in the front yard that work, but for testing, I wanted something with headphones. I guess I got rid of all my basic radios at some point.

I'm the only person in my family who doesn't have an ipod (or any i-device, as my wife totes an i-pod, and i-phone, and an i-pad..she's all in with the whole Steve Jobs approach to technology...), but from what I read, the nano is the only ipod with an FM radio. Since they allow you to start and resume FM broadcasts, makes sense they are doing digital storage and delaying it a split second.

I'm glad I know that now, as my daughter has one, and I can see myself scrambling to figure out the 1/2 second delay as she helps test lights listening to her nano for audio.

I found the Nano delay when testing out my RDS signal. Had main radio going right in time with the music and Nano going and it's quite an effect. I suppose I could have paused it on the nano a little longer and created an echo effect. Hmmm, what lighting effect would I program for an echo?
