Hello Everyone,
I'm completely new to this forum and Arm processors so please forgive any transgressions.
I'm looking at building a drum machine using a microcontroller and an audio DAC. So far I've used a Microchip 16 bit PIC and a VS1053 board which all works fine except for the fact that there is audible latency between the trigger and the sample being played. I finally tracked this down to the VS1053 itself.
After a fair bit of research I've come to the conclusion that an Arm chip such as the one in the Teensy 3.5 would be a much better option and there is already an audio board available. So, finally, my question. Before I spend 15 or so of my hard earned pounds on the Audio Shield could anyone tell me if there is any latency associated with the SGTL5000 chip itself? The datasheet doesn't suggest any but then, neither did the VS1053 datasheet.
Any help would be greatly appreciated.
Regards,
Sharpie
