<h1>Speech-free &amp; music-free source clips <small>&mdash; a random sample of 12</small></h1>
<p class="lede">Drawn at random (seed 20260809) from the <b>8,191</b> clips that survived a two-stage
audio filter over 101,503 source videos from InsAVE-80K and JAVEdit-100k: no speech
(FireRedVAD, then FireRedASR2-AED confirmation on every VAD positive) and no music-related
AudioSet tag anywhere in the top five. These are the <i>inputs</i> to the removal pipeline, not its
outputs. Play with sound on.</p>
<div class="facts">
  <div class="fact"><b>101,503</b> <span>clips screened</span></div>
  <div class="fact"><b>31,845</b> <span>speech-free</span></div>
  <div class="fact"><b>8,191</b> <span>also music-free</span></div>
  <div class="fact"><b>12</b> <span>sampled at random, not curated</span></div>
</div>
</header>

<div class="note">
<b>Sampled, not cherry-picked</b> &mdash; so the failure mode is visible too. 3 of these 12 carry
<code>Speech</code> as their top AudioSet tag even though VAD and ASR both cleared them. That is the
known model disagreement: FireRedASR2 covers Chinese and English, so speech in another language
transcribes empty and slips through. Those clips are flagged in the manifest via
<code>speech_disagreement</code>, and the stricter variant
(<code>kept_no_speech_strict.csv</code>, 6,983 clips) drops them.
