Start a ConversationIs this you?
Your noise reduction or audio processing performs well in controlled conditions but degrades badly in real-world deployment. You need an expert who can diagnose why and fix it.
You have a signal processing design that performs well in simulation but needs to run on a resource-constrained embedded target. Fast, efficient implementation is a different art.
Complexity in a speech or audio pipeline rarely announces itself. It accumulates in the gaps between teams, between vendors, between what was specified and what was built. The right outside perspective can cut through it quickly.
In Their Words
"We were fortunate to connect after struggling for months with another SW company. Steve was able to understand our objectives right away and implement a solution in Audio Weaver within the agreed time and budget. He is our first call going forward."
David Warner CTO, Exemplar Audio
"Steve was critical to my project, providing deep experience in a specialized signal processing field. He was adaptable to evolving needs and created and delivered effective software. A pleasure to work with!"
Andy Draudt Principal Investigator, Triton Systems Inc.
Selected Work
Challenge
Design methods proposed by previous consultants relied on engineering intuition that the client's internal team did not possess — creating a dependency that slowed progress and raised cost.
Outcome
Challenge
A highly complex system-level design involving many stakeholders: gate agent PA systems, audio transport to server, third-party STT and LLM integration, and end-user app delivery. No one had defined where voice processing ended and other concerns began.
Outcome
Approach
A focused first phase to map the problem, identify the critical unknowns, and give you a clear picture of what's actually blocking you — before committing to anything larger.
An independent review of a proposed design before you build it — pressure-testing assumptions and surfacing risks while there's still time to change course.
Sustained work alongside your team as an integrated technical lead — algorithm design, implementation guidance, and mentoring. Remote-first with on-site when it matters.
Not sure which fits? A 30-minute conversation costs nothing.

Audyl LLC is led by Steve Isabelle, an independent DSP consultant with a PhD in signal processing and a career spent turning hard acoustic and speech problems into shipped products.
Steve's foundation is in the rigorous theory of signal processing, applied to real products at Bell Labs, Bose, Nvidia, and DSP Concepts. He has led engineering teams at the first, second, and third level — so he understands both the technical and organizational dimensions of hard problems, and knows how to leave teams stronger than he found them.
The specialty is the work that's too theoretical for a firmware team and too practical for a research lab — algorithm and architecture design, custom design tooling, and guiding implementation teams through the details that matter.
