Digital VU-Meter, Real Time Audio Analyzer -- 2

You have to design and build an Digital VU-Meter/RTA Analyzer that would mimic the behavior of an Analog VU, and Real Time Audio(RTA) Analyzer with multiple choice of colors. Similar to the one in the pictures and video I attached here. I have the display which is a phone display 3.2" 640x360 TFT and I will accept NO OTHER display. It has to accept mono audio signal and be as accurate as possible in displaying the audio signal amplitude in VU and amplitude and frequency in RTA mode. I will give more functionality details after awarding the project. You have to provide a working unit, electronic schematics and code for the MCU.

Just bid whatever that you consider it's fair for you. I may not award the lowest price.


I already spent 6 months and hundreds of dollars working with a promising engineer on this project just to be told that he can not do it. This will not happen again.

Here are two videos showing something similar to what I want:

Thank you

I done similar project, the sound processing with output to TFT, used controller STM32F429I. VU-Mode and RTA Mode is not a problem, I can use two layer frame buffer. I will be glad to do this for you.

Hello, Have a great day. I am representative of a startup company I-TECH. We will ship a fully tested and working device based on Arduino due (we need high speed ADC and DAC, ARM can also serve the purpose) and TFT. Lagi

Hello, I have been watching this project since it was posted yesterday as it tends to attract a lot of automated responses and people who claim to be able to do things. As you have had a prior bad experience I have Lagi
