Hello,
i want to process Audio. See my Block-Diagram attached.
For this i need some assessment if this is possible or not.
detailed description of my project:
I want to mix the line input from SGTL5000 #1 with SGTL5000 #2 and additional the input from a mic (over PCM1803A ADC) -> PCM1803A compatible with audio library? maybee there is some "better" chip, which also handles the section "2x microphone preamp"?
On SGTL5000 #1 the line output is connected to a power amplifier. For this i need volume and tone control (5 Band EQ). -> Could be done with SGTL5000 or should i use an external ic for that?
The output from the second SGTL5000 is connected to a "FN-RM01" mp3 sound recorder module. This module should record the mixed output but without volume changes so level of recorded audio file is constant (maybee with automatic gain control?) -> necessary?
As a general rule i want to have the opportunity to change some settings.
for example:
- only "internal" OR the "external" microphone is connected to the recorder module (SGTL5000 #2).
- OR the mix from both SGTL5000 is connected
- OR the mix from both SGTL5000 AND one of the microphones is connected.
The last thing: The PT2811 should be able to output the signal for a subwoofer. I need settings for volume an cut off frequency.
Is this a possible concept?
Thank you!
Regards Danie
