Hi,
I'm interested in making a digital audio recorder. The idea would be to record incoming SPDIF signal onto an SD card. The signal would be 24-bit resolution with 96kHz sampling rate. I don't have much experience with microcontrollers except for playing around with an arduino, so I was hoping I could get some advice from more experienced people.
To work with I2S reliably, I expect the MCU has to have at least some level of hardware I2S support. On the other hand, writing to the SD card while receiving real-time data means that there has to be a substantial amount of memory available and a DMA controller would probably save me a lot of trouble.
Can you guys point me towards good MCU candidates for a job like this? It would be especially great if there was a development platform which integrates the SD card reader, MCU and a programming interface. I fully expect that I need to integrate the high resolution SPDIF codec though.
Thanks
