I will program audio dsp firmware and configure codec registers
About this Gig
Is your audio hardware completely silent, or suffering from distorted communication? I will write stable firmware and properly program your audio DSP chips and hardware codecs.
I bridge the gap between your microcontrollers and digital audio ICs for flawless playback.
What I Do:
Audio Codec Initialization: Deep configuration of registers for chips from TI, Cirrus Logic, and ESS Tech.
DSP Tuning (SigmaStudio / Audio Weaver): Graphic EQ tuning, compressors, multi-band limiters, and noise gates.
Interface Troubleshooting: Fixing timing mismatches on I2S, TDM, PDM, and clock configurations (MCLK/BCLK/LRCLK).
Platform Support: Expert programming for ADAU1701/1452, XMOS, STM32, ESP32, and Teensy Audio.
Deliverables: Well-commented source code, compiled binaries, or structured SigmaStudio configuration profiles.

FAQ
Do I need to send you my physical hardware board to complete the firmware?
In most cases, no. If you provide your complete hardware schematic diagrams and datasheet links for the chips, I can write the exact register maps, initialization routines, and driver frameworks remotely. For complex DSP tuning, I provide configuration profiles you can flash yourself.
What software tools do you use for programming audio DSP chains?
I work extensively with Analog Devices SigmaStudio for ADAU processors, TI PurePath Console for Texas Instruments chips, and write bare-metal or RTOS-compliant C/C++ drivers inside STM32CubeIDE or ESP-IDF for host microcontrollers managing I2S/TDM pipelines.
Can you resolve audio popping, cracking, or complete silence on my current board?
Yes, these issues are almost always caused by timing register errors on the I2S/TDM bus lines (mismatched MCLK, BCLK, and LRCLK clock configurations). I will audit your register settings to align master-slave clock parameters across your audio devices.
