ACR Recorder

ACR Recorder captures audio with configurable metadata to support reproducible research and documentation. It records from a selected input source at a chosen sample_rate and channels, then exports to WAV, MP3, or FLAC with tagged metadata. The system emphasizes consistent naming, timestamps, and tag templates so each session is self-descriptive for downstream transcription or analysis. Conceptually, it treats each recording as a data unit with both audio content and descriptive metadata, enabling reliable search, filtering, and audit trails. Typical users include field engineers, researchers, journalists, and developers who value precise control over capture quality and data provenance. Core value lies in predictable file sizes, deterministic metadata, and flexible export options that fit existing processing pipelines. Core features include multi-field input configuration, real-time capture, metadata tagging, multiple output formats, duration control, and basic integrity checks. Use cases span lab experiments, interview capture, and process documentation where later analysis or compliance requires traceable data. The tool differentiates itself by combining strict input validation, structured metadata schemas, and export-ready outputs without relying on third‑party transcription or streaming services. It is particularly valuable for teams that need repeatable capture settings across devices and sessions, ensuring consistent data for QA, archival, and compliance workflows.
Example: configure 44.1 kHz, 2 channels, WAV, add tags like project, date, and device, then export for transcription or archiving.
Advanced users can enable optional silence detection and hash-based integrity checks to ensure data integrity across transfers.
