An MP4 with “sone” in the name would likely contain:
Files named with sequential indices sone-XXX in similar projects often run between 30 seconds and 3 minutes each – a manageable chunk for indexing and error recovery. Frame rate is likely 24 fps (cinematic) or 30 fps for screen capture. MOSAIC-ARCHIVE-sone-104.mp4
The sone-based loudness may be recorded at very low amplitude to preserve headroom. Normalize to -23 LUFS for audibility, but keep the original untouched. An MP4 with “sone” in the name would
Several universities (e.g., SONIC Lab at Stanford, or the former Mosaic Sound Project) used “sone” indices to catalog time-based media. This file might contain a spectrogram visualization paired with sonified neural or astronomical data. For example, converting the rotation of a pulsar or the firing of neurons into audible frequencies, overlaid with explanatory video. Normalize to -23 LUFS for audibility, but keep
