Fixing AI: When the Problem Is Actually Analog

Sometimes an AI problem isn't actually an AI problem. It's hardware.

Carter Huffman (CTO and Co-Founder at Modulate, a Voice Conversion technology company) explains how something as simple as an Ethernet cable created interference in analog audio signals used for machine learning data. Because the audio was converted from analog to digital later in the signal chain, electrical interference could affect the recordings before they ever reached the AI model.

It's a practical example of why audio engineering and signal processing matter when building Voice AI. Better machine learning models can't automatically fix bad input data caused by microphones, electronics, analog-to-digital conversion, or hardware interference.

For AI engineers, this is an important reminder: when an AI system produces bad results, the problem might start long before the software.

Have you ever spent hours debugging software only to discover the real problem was hardware?
