Where are meeting audio recordings saved, and how are files formatted?

Local Audio Storage with Zero Cloud Footprint

Cloud meeting assistants upload full-length audio recordings to proprietary remote cloud buckets (such as AWS S3). You rarely have direct file access, and downloading raw audio requires hunting through complex administrative web dashboards.

Oyma stores every recording as an ordinary file directly inside your local knowledge vault.

File Storage Location and Naming

By default, audio files are organized in a designated directory within your vault:

~/Documents/Vault/
└── 02 Meetings/
    ├── 2026-10-09 Product Review.md
    └── recordings/
        ├── 20261009-143000-product-review.m4a
        └── 20261009-143000-product-review.vtt

• Clean File Format: Audio is encoded in industry-standard Advanced Audio Coding (AAC) inside an .m4a container.
• High Audio Quality: Stereo 48 kHz sampling with a bit rate of 96 kbps yields crisp vocal clarity while minimizing storage usage.
• Storage Consumption: A standard 60-minute meeting recording consumes approximately 42 MB of disk space.
• Sidecar Transcripts: Time-aligned subtitle tracks are saved alongside as standard WebVTT (.vtt) files for universal player compatibility.

Automatic Retention and Archiving Rules

In Preferences > Audio & Storage, you can configure automatic retention policies:

• Keep all audio indefinitely.
• Automatically delete raw audio after transcription and summary generation to save disk space.
• Archive audio files to an external drive or network share after 30 days.

Audio Asset Retention and Disk Management

Keeping your vault lean while maintaining important meeting records:

• Configurable Retention Windows: In settings, choose to automatically archive or delete audio files older than 30, 60, or 90 days while preserving the text transcripts forever.
• External Storage Redirection: Direct your audio recordings folder to an external SSD or network share while keeping your Markdown notes on your primary Mac drive.
• Portable Relative Linking: Notes link to audio files using relative Markdown syntax, allowing you to relocate your vault without breaking audio playback.

Standard Formats and Universal Media Compatibility

Recordings are saved as industry-standard AAC .m4a files. You can listen to them in Apple Music, QuickTime, VLC, or any mobile audio player without converting formats or relying on proprietary vendor playback tools.

Sidecar WebVTT files (.vtt) are also generated alongside every recording, allowing you to load transcripts as subtitles in video players or import them into external analysis tools.

Storage Specifications and Formats

• Audio Container: Standard Advanced Audio Coding (AAC) in .m4a format at 48 kHz stereo.
• File Location: Stored in vault’s recordings/ folder directly on your Mac NVMe drive.
• File Size: Approximately 42 megabytes per 60 minutes of recorded meeting audio.
• Subtitles: Accompanied by standard WebVTT (.vtt) files for universal player compatibility.
