About
Noise Blocker is a Windows microphone utility that uses real-time AI noise cancellation to reduce background noise before it reaches calls, recordings, streams, or voice chat. Audio is processed locally and supplied through a virtual microphone to Zoom, Teams, Google Meet, Discord, Slack, OBS, and other apps.
Version 3 is a ground-up rebuild that replaces the recorded-sample workflow with automatic cancellation for keyboard and mouse clicks, fans, hiss, and room noise. It also includes voice activation, loudness equalisation, a configurable noise gate, real-time monitoring, and global push-to-talk, push-to-mute, and toggle shortcuts.
Noise Blocker supports Windows 10 and 11. Try it without an account or email with 30 free minutes each week. A personal licence is a one-time purchase—not a subscription—and unlocks unlimited use with 12 months of updates and priority support. The eligible installed version keeps working afterward; renewal is optional.

About
Audible's ACX has eight technical checkpoints, and a file that misses one comes straight back. chapterpass masters each chapter file to spec: RMS loudness between -23 and -18 dBFS, peaks held below -3 dBFS, a noise floor under -60 dBFS RMS, room tone at the head and tail, and a 192 kbps CBR MP3 on the way out. Every output is verified against the full spec before download, and you see the measured value next to the requirement for each checkpoint. The processing runs in your browser through WebAssembly, so your audio never leaves your device. There is no account to create. Your first file is free, then $36 per finished hour, $27 from 5 hours, $18 from 10 hours, billed by the second. A free measurement page at /free-acx-check reads your loudness, peak, noise floor and silence padding against the spec without mastering anything. chapterpass masters the measurable technical specs. It does not edit your recording, remove noise, or fix narration.
