Audio Rate analysis dashboard.
Our team is exploring exercise-exertion estimation from breathing audio. I work on the analysis dashboard, signal processing, data analysis, and connections between devices.
From recording to reviewable data
- InputWAV recording
Streamed and analyzed in bounded file chunks.
- AlignEvent timing
Integer nanosecond timestamp subtraction.
- MeasureSignal measurements
Interval measurements across the session.
- ReviewPlots + session checks
Sample-rate and checksum integrity checks, interval exports.
My contribution
I developed the browser-based post-capture analysis dashboard, including streamed WAV processing, interval signal measurements, event alignment, and session-integrity checks.
- Analyze recordings in bounded file chunks rather than retaining a full recording sample array.
- Align captured events to audio using integer nanosecond timestamp subtraction.
- Check recording sample rates against session metadata and verify supplied file checksums.
- Support analysis plots and interval exports for reviewing recorded sessions.
Engineering focus
My work focuses on making captured data inspectable: preserving timing, handling large recordings, and exposing signal measurements and session inconsistencies before downstream analysis.
The dashboard is part of a larger team pipeline. Its measurements are signal-analysis outputs, not a completed or validated exertion prediction.
