I've got several embedded projects using an ADAU1701. I cannot watch the dB levels in realtime in sigma studio since I program the DSP using an embedded MCU.
I have the gain path optimized between the DSP and the amplifiers so I need absolute maximum output, with a dB or two of headroom. To maximize the output level without clipping, should I be limiting to -1dB or can we go to +2dB (the maximum of the level meter - 1dB)?
Thanks in advance!
