Conceptual reference architecture. Processing location, storage strategy, connectivity and AI services vary by project.

A wearable recording device brings acoustic engineering, recording control, storage, power, connectivity, software and AI together. Integration choices depend on the product requirements.

Engineering the Recording Experience

Capture

Audio & Acoustics

Audio and acoustic engineering begin with how a device is worn. Microphone placement, acoustic openings and the acoustic path need to work with enclosure geometry and structural materials. The microphone and audio interface, power supply and PCB layout are considered together, including electrical noise that could affect capture.

Capture configuration and processing are evaluated for the intended use. Automatic gain control (AGC), noise suppression or acoustic echo cancellation (AEC) may be considered where the architecture calls for them. Evaluation sets recording-quality targets.

Embedded, Storage & Power

Embedded recording firmware coordinates start, pause, stop and recovery behavior with buffering, audio encoding and local file writes. Storage design covers recording segmentation, retention and what happens when available space is full.

Power management balances capture, processing and storage activity with sleep and wake states. Wireless scheduling, battery constraints and active-state behavior inform the tradeoffs between recording quality, stored data and when recordings can be transferred.

Each decision shifts the balance across the system.

Connect

BLE & Device Workflow

BLE connectivity can support device binding, recording control and battery or storage status. Device synchronization is designed around recording access and interruptions, so the application can handle incomplete transfers and reconnection. Depending on requirements, the workflow may also include firmware updates over the air, with update behavior coordinated across the device and mobile app.

The conversation continues

From Recording to Useful Information

“How should the next prototype be worn?”

00:24:26
“How will we organize the recordings?”

00:24:34
“Agreed. Let’s review the device and app requirements together.”

Structured notes

Example notes for review

Summary: Prototype wearability and recording organization.
Key Points: Wearing position · Recording organization · Device / app requirements
Decisions: Review device and app requirements together.
Action Items: Confirm recording organization.
Search / Knowledge: Prototype review · Wearability · Recording workflow

The mobile application can bring recording synchronization, file management and content access into one workflow. Depending on the architecture, a backend can coordinate uploads, storage and cloud processing. A selected speech-to-text service can transcribe recorded audio, with language coverage and processing choices evaluated for the intended use.

AI summaries may organize transcripts into key points, decisions and action items, or follow structured templates. Tags and searchable content can support retrieval and knowledge workflows as a recording library grows. Outputs need human review against the source conversation; the selected services and application requirements determine what the system can support.

Built Around Real Conversations

Sales Conversations

Capture customer discussions and organize requirements, decisions and follow-up information from the recording for review.

Meetings

Use recorded discussions to prepare summaries, decisions and action items that participants can review.

Interviews & Research

Preserve long-form conversations and make recorded information easier to search, review and retrieve.

From Product Definition to Delivery

AI recording wearable development brings hardware, firmware and connected services into one product brief. Responsibility is defined around the project requirements.

Engineering responsibility

Hulin Engineering

The engineering scope may include:

Product Definition & Mechanical: Define recording requirements, wearability, enclosure geometry and mechanical integration.
Hardware & PCBA: Select components and integrate audio, power, connectivity and storage.
