Is it possible to create a looper with pedalshield DUE?
I know that since Due can in real time convert a signal to digital, modulate it and then convert it to analog again, it may seem that this is no problem.
But, for this particular application more variables are inserted. For example, where is the "song" recorded stored?
EEPROM? Sdcard?
Is the access time of the external component quick enough for on the fly read/write?
What would be best to use of these two?
The "song" format would be .wav?
Thanks a lot!

Hi, I had this idea some time ago but never find the time to do it.
I reckon that the best way to do a looper is to use a I2C ram memory, there are some 1Mb i2c SRAM dip8 chips on mouser for a reasonable price....
There are plenty of options, havea look at this: hackaday.com/2011/09/07/want-2-megabytes...am-for-your-arduino/
About reading wav files... I dont think is feasible, arduino does not have an OS and I think it is not able to read a wav without maybe struggle and waste al the resources.
