Implementing LPC Audio Playback on a 10-Cent Microcontroller with 16K Flash Memory
By

Pulled from the oven just right. Trustworthy, fact-dense, deeply satisfying.
Summary
The article demonstrates how to fit approximately 7 seconds of audio into 16K of flash memory on a 10-cent microcontroller unit (MCU) while still leaving room for code. It explores using LPC (Linear Predictive Coding) encoded audio playback on extremely low-cost hardware, showing practical implementation details for embedded audio applications on budget microcontrollers.
Key quotes
· 4 pulledYes, you can fit about 7 seconds of audio into 16K of flash and still have room for code.
And you can even play LPC encoded audio on a 10 cent MCU.
There's quite a lot more detail in this video (and of course you can hear the audio!).
TLDR: Yes, you can fit about 7 seconds of audio into 16K of flash and still have room for code.
