Host: Mac mini; Apple M2; 8 logical cores; macOS 27.0.1 Arm64
ISA: neon crc32 aes dotprod
Storage of the corpus: /dev/disk3s5; every file is read once before its rows, so it is in the page cache for all of them
.NET: 10.0.11 (.NET 10.0.11)
Load average (1 min): before 2.32; during mean 2.18, max 2.41 over 27 samples at 5 s; after 2.02
Elapsed: 2.2 min; repetitions 5 (managed), 3 (tools); files over 1 GiB get one warm-up run and 3 samples of one run each, and tools once
Packages as restored: SharpMP4 0.3.2; RecursiveAI.OneAudio 1.4.0; MetadataExtractor 2.9.3; TagLibSharp 2.3.0.0; z440.atl.core 7.19; Matroska 0.0.12
Tools: ffmpeg version 8.0 Copyright (c) 2000-2025 the FFmpeg developers; MP4Box - GPAC version 26.07-revrelease; mkvmerge v103.0 ('The Darkness') 64-bit; MediaInfo MediaInfo Command line,; ExifTool 13.60

Ratio is OneMedia's median over the fastest managed comparator's median on the same file (below 1.00× is faster). Peak is the process's peak resident set; Baseline is its resident set before any work, so Peak − Baseline is what the work added.
