I'm making a DAW to be connected to a USB device. The analog source and destination are 1/4 inch analog jacks. I would like the device to be full-duplex, USB compatible with windows, and 24 bit audio, at least 105db SNR, at least a 48K sampling rate, and at least 2 channels for both input and output. I am wondering what ICs, and what uP in particular, I should be considering for this design. Here's what I have so far:
-PCM1861: ADC
-AD1934:DAC
-TMS320C5533:DSP
Although the TMS320C5533 has 4 I2S buses and supports USB, I am wondering if it has the ability to convert I2S to USB and vice-versa. I am also assuming that 4 I2S buses means the TMS320 can interface with 4 exterior I2S signals at once, correct?
