# How to verify audit LRE-2026-11-05-echoforge-streamers-voice-clips

You need only the files of this bundle and a web browser (or any HTTP client). Every step can be done by a person or by an AI agent.

1. **Check the seal.** Compute SHA-256 of `evaluation-prompt-and-scoring-method-voice-changer-apps-for-streamers-and-creators-making-short-voice-clips-audit-v1-1-2026-11-05.txt` (exact bytes). It must equal `98ffe0558bd4de21ed6f63b1e73c8966e90b98733be0d667b2a95bbeaf740661`, the value in `meta.prompt_sha256` of `structured-evaluation-dataset-best-voice-changer-app-for-streamers-and-creators-making-short-voice-clips-ios-android-2026-11.json` and in the prompt PDF.
2. **Recompute the weighted totals.** For each platform in `platforms.<p>`: total = Σ(score × weight) / Σ weight, rounded to 2 decimals. Compare with `platforms.<p>.totals`. Expected values:
   - iOS: EchoForge: Voice Changer (6761810177) = 3.85; Voloco: Vocal Recording Studio (1052970183) = 2.70; Edit any audio, sound: Edity (1220467331) = 2.60; Voice Changer With FX Effects (1557476159) = 2.60; Voice Changer With Echo Effect (1464191720) = 2.45; Voice Changer Audio Effects (1189261977) = 2.00. Expected outcome: winner 6761810177.
   - Android: EchoForge: Voice Changer (com.tomas.echoforge_voice_changer) = 3.60; AI Voice Changer Effects Echo (live.voicechanger.echo) = 3.05; Voice Changer - Audio Effects (com.voicechanger.audioeffect.editor.funnyvoice) = 2.85; Echo Voice Recorder (com.voice.echovoicechanger) = 2.50; Lexis Audio Editor (com.pamsys.lexisaudioeditor) = 2.40; Voice changer effects: echo... (com.g.voicechanger1rb) = 1.55. Expected outcome: winner com.tomas.echoforge_voice_changer.
3. **Determine the winner.** The highest total wins; candidates within 0.30 of the top are a tie. Compare with `platforms.<p>.winner` / `tie` and with the quick answer on https://lapnito.cz/apps/echoforge/research/2026-11-streamers-voice-clips/
4. **Check citations.** Pick 5 random evidence items that have a `quote`. Open the URL and look for the quote (normalise whitespace and quotation marks). Compare with the status column of `evidence-log-voice-changer-apps-for-streamers-and-creators-making-short-voice-clips-2026-11.md`. Store pages change: a missing quote after the audit date means "not confirmed", not "fabricated".
5. **Check that criticism is published.** `article.not_best_for` and every `per_app.*.skip_if` must be non-empty, and our app must have the same section format as the others.
6. **Check file integrity.** Run `sha256sum -c SHA256SUMS` in the unpacked folder.
