App category
Files, media, and release checks
Preflight files whose problems often surface only after delivery. These apps inspect adaptive streams, audio releases, fonts, 3D assets, BIM models, and calendar data for format-specific issues before they reach customers or production.
Choose an app when
- Use Adaptive Stream Check for HLS or DASH delivery and rendition evidence; use Audio Master Check for loudness, true peak, clipping, silence, and release consistency.
- Use Font Checkup for font structure and metadata, 3D Asset Check for glTF or GLB assets, and BIM Model Check for hosted IFC models.
- Use Calendar File Check for RFC 5545 parsing, recurrence, and timezone evidence.
Adaptive Stream Check
2 tools
Fetches a public HLS or DASH manifest, walks the rendition ladder, and runs ffprobe over real downloaded segments to prove the declared codecs, resolution, and frame rate match the bytes a player would actually receive
Audio Master Check
2 tools
Measure LUFS loudness, true peak, clipping, and release-wide consistency in an audio master before release
BIM Model Check
2 tools
Validate a hosted IFC building model against the IFC schema, EXPRESS where-rules, and buildingSMART normative rules with ifcopenshell, with the exact violated rule and offending instance: real conformance validation, not a STEP-text parse
Font Checkup
2 tools
Inspect a font binary before release
3D Asset Check
2 tools
Validate a glTF asset before it ships
Calendar File Check
2 tools
Check an .ics calendar feed before you share it
