Cleanvoice AI

Pros

  • + Room-tone gap fill made removals inaudible in my 42-minute test — I could not locate edit points without the marker list
  • + Timeline export to Audition, Premiere, DaVinci Resolve, Reaper, Audacity or .EDL let me restore two over-eager cuts in about three minutes
  • + Cost per episode is trivial: roughly $0.77 of processing for a 42-minute episode at the $11/10-hour tier in my test
  • + Multitrack uploads noticeably reduced false-positive cuts versus single-track stereo in my comparison
  • + Unused subscription hours roll over up to 3x the plan limit and pay-as-you-go credits stay valid two years

Cons

  • - No free plan — only a 30-minute trial; default filler sensitivity took two intentional rhetorical pauses in my test
  • - Files are deleted 7 days after processing, so you cannot leave exports sitting
  • - No shared team workspace on any plan, which limits agency workflows
  • - Not a creative editor — no music, arrangement or text-based content editing
  • - Heavy accents and severely noisy or overlapping speech still need manual cleanup, per user reports and my own noisy test file

AssemblyAI

Pros

  • + Transparent, published rate card: $0.15/hr for Universal-2 and $0.21/hr for Universal-3.5 Pro at time of writing (assemblyai.com/pricing.md), with worked examples showing exactly how add-ons stack
  • + $50 in free credits at signup with no credit card required, so I could benchmark real audio before paying anything
  • + Guardrails (PII audio/text redaction, profanity filter, content moderation) are first-party add-ons instead of a second vendor contract
  • + EU data residency at the same price as US processing — no GDPR surcharge in my review of the rate card
  • + Voice Agent API bundles STT + LLM + TTS + turn detection at one $0.075/min rate, which I found cheaper than assembling the same pipeline by hand

Cons

  • - No end-user app: everything runs through the API, so non-developers have no path in
  • - Streaming bills by open-connection time, not audio sent — an idle socket left open after a call keeps charging in my testing
  • - Add-ons stack on the base rate until a 'cheap' transcript approaches $0.40–$0.60/hr for the feature set most teams want
  • - Long-file processing is async only; no synchronous option for large uploads
  • - Legacy Auto Chapters and Summarization add-ons are deprecated and can fail silently on newer models per the vendor's own pricing reference
