v1.7.0

[1.7.0] - 2026-10-11

• m4a/aac-64k-44k-30s.m4a: AAC at 64 kbps and 44.1 kHz, beside the 128 kbps, 48 kHz file.
• opus/cbr-32k-30s.opus: Opus at a constant 32 kbps.
• wav/sine-440hz-3s-48k-24bit-stereo.wav: 24-bit PCM behind the 68-byte extensible header.
• md/long-with-toc-and-footnotes.md: a long document whose contents links and footnotes all resolve.
• docx/anchored-image-with-alt-text.docx: one JPEG floating in an anchor, with alt text.
• hls/multi-bitrate/master.m3u8: a master playlist over a new 360p rendition in hls/360p-10s/
  and the existing 720p one, its BANDWIDTH, RESOLUTION and CODECS measured from the segments.
• New measured props, existing bytes unchanged: bitrate_kbps from the audio packets and
  bit_depth for PCM on every audio file, the WAV header's format and size, the video
  profile and H.264 level, inline and anchored images and alt text on every DOCX, and
  headings, anchor links and footnotes on Markdown.
• Four audio descriptions now say what was measured: opus/30s.opus averages 114 kbps, not
  the 96 it was encoded for; aac/adts-30s.aac is 130.6 kbps with its frame headers;
  ogg/vorbis-30s.ogg no longer names an encoder quality; and the 3-second MP3's extra
  24 ms is one 1152-sample frame.
