Audio Noise Reduction on STM32 MCU Discovery

$250-750 USD

Paid on delivery
The primary goal of this project is to develop a hobbyist DSP encoder/decode device, loosely based on the analog dbx technique which seats in between a users digital music source (PC phone etc…) and any low-cost current cassette players/recorders available for purchase from the likes of Amazon and Walmart etc. Besides providing real time encoding/decoding capabilities it will also provide sound level meter bars, digital equalizer functionality, tape counter, and music metadata to display to user if possible (can’t think of simple way to do this). This user interface would essentially mirror those found on the older cassette decks. For the microcontroller hardware, the excellent STM32F746G discovery board will be used since it already has the audio jacks, along with a 4.3” touch screen for doing the user interface. Moreover, sample code and an audio library exist so it shouldn’t be too difficult for an experience programmer to implement the code. So if you are a programmer with some DSP/STM32 experience and are looking for something fun and completely impractical to put your time into please apply. The code will be published using open source license on GitHub.

Dear Sir, We are a small R & D company, based in Bulgaria, Europe. We work exclusively with U.S. partners. We specialize in developing Embed systems based ST(STM32), Microchip (Atmel )(PICs,AVR,Atmel ARM) and TI (MSP430) MCPUs and peripheries. For our mobile devices use ESP32 and nRF51/52xxx BLEs. We realize projects with requirements similar to yours. Our tools for design STM32 based systems: Keil ARM Atollic TRUEStudio STM32 Discovery boards ST Link emulator progremmer - separate from Diccovery boards If we receive more information about your project, we will give you a real cost and time to implement your project. We based in Europe, not customs problems for delivery models and samples for testing Best Valeri T.

Thank you for inviting me. I understood your requirements. We can implement dbx noise algorithm on Stm32. Currently I've less bandwidth and busy with other projects. I've good exposure on dsp algorithm implementation over 5 years. Did you have mathematical note for noise reduction algorithm. I'm also have your prescribe hardware with me. May I know the exact timelines for this project.
