    Good evening Mr Hamster The project is very interesting. I am a student and if u Could you help me?. I want to send audio. You said, audio with 16-bit resolution high quality mono. 1221381325 + / - 1.000.000 but I don´t understood very well that I add audio input in the process.,and what signal I use. This would be: if beep_counter(19) = '1' then phase_accumulator <= phase_accumulator + 1222381325; else phase_accumulator <= phase_accumulator + 1220381325; end if; else phase_accumulator <= phase_accumulator + 1221381325; -- +/-1000000 end if; This is my email: rafael_u_r@hotmail.es my fpga is DE2-115 Cyclone IV and the audio codec is WM8731: Audio Codec, Signal name: AUD_ADCLRCK --Audio CODEC ADC LR Clock AUD_ADCDAT --Audio CODEC ADC Data AUD_DACLRCK --Audio CODEC DAC LR Clock AUD_DACDAT --Audio CODEC DAC Data AUD_XCK --Audio CODEC Chip Clock AUD_BCLK --Audio CODEC Bit-Stream Clock I2C_SCLK --I2CClock I2C_SDAT --I2CData My apologies if I ask too much, but it's a project, I'm doing at my university. I look forward to hearing from you soon. Yours sincerely Rafael Urquizo from Peru.
