About this Gig
I'm a DSP audio And electronics engineer. I design clean, low noise audio
processing circuit boards DSP, preamps, and amplifiers that sound great and go
straight to production.
WHAT I CAN DESIGN:
DSP audio processing boards EQ, filters, crossover, effects
Preamplifiers mic, phono/RIAA, line, studio preamps
Audio amplifiers headphone, speaker, power amp
DAC / ADC boards I²S, USB, Bluetooth audio
Audio mixers, crossovers, and processing circuits
Clean power supplies for audio low ripple, low noise
WHAT YOU GET:
Clean, professional audio schematic
Low-noise DSP PCB layout star grounding, ground plane,
analog/digital separation no hum, no buzz
Proper DSP integration codec, ADC/DAC, audio processing
DFM check so your board actually builds
Industry-standard outputs Gerber, BOM, Pick & Place
MY TOOLS: KiCad, EasyEDA, Altium Designer
WHY WORK WITH ME:
Real low-noise audio design, not just a drawing
Clear communication & fast delivery
Free small fixes until you're 100% happy
Message me your audio idea and I'll reply with a plan and quote within a few hours.
Order the Standard package and I'll get started today!
FAQ
Can you design a DSP audio PCB from my idea / circuit?
Yes. Send your requirement, input/output specs, and any schematic or reference. I'll design the schematic and low-noise layout with proper DSP integration.
What DSP chips do you work with?
I design around common audio DSPs and codecs (e.g. ADAU1701, PCM-series DACs, CS, TI audio DSPs, and microcontroller-based DSP) — tell me your chip and I'll route it cleanly.
Will my board have hum or noise?
No — I use star grounding, ground planes, and analog/digital separation to minimize noise and interference in the audio path
Can you design a preamp or amplifier separately?
Yes — preamps, amplifiers, and complete audio processing boards are all within my scope.
