Plug-and-Play DSP Module for Speaker Manufacturers

P6/10April 27, 2026

WhatA tiny, pre-certified DSP module based on the Pico that speaker and audio equipment OEMs can drop into their products for crossover, EQ, and room correction without designing custom DSP hardware.

SignalThe fact that a $4 microcontroller can now run real audio DSP firmware suggests the cost floor for adding intelligent signal processing to consumer audio products has collapsed, but there is no productized module OEMs can simply buy and integrate.

Why NowThe RP2350 with PSRAM support and AI-assisted firmware development have made it possible for a tiny team to build production-grade DSP on commodity hardware for the first time.

MarketSpeaker OEMs, amp manufacturers, and DIY audio companies; ~$2B global speaker components market; competes with MiniDSP OEM modules and Analog Devices SHARC chips but at 10-20x lower cost.

MoatFirmware ecosystem and integration support — once OEMs design around your module and toolchain, switching costs are high because filter configs, calibration profiles, and production tooling are all tied to your platform.
