Pulse saves recording data as you record, allowing you to recover the audio captured before the interruption. ▸ Record Multiple Tabs Simultaneously Capture audio from several Chrome tabs at the same time. Each recording is saved as a separate file, with independent settings, timers, and controls. ▸ MP3, WAV, and WebM — No Lengthy Conversion Choose your preferred format before recording: • MP3 — Universal compatibility with bitrates up to 320 kbps. • WAV — Lossless audio quality. • WebM — Compact audio files. Audio files are created during recording, so there's no need to wait for lengthy conversion after you stop. ▸ Record Without Sound from Your Speakers Mute audio playback from the selected tab through your speakers or headphones while continuing to record its sound. ▸ Smart Silence Detection Pulse automatically skips extended periods of silence and resumes recording when audio returns. Get audio files without unnecessary silent sections. ▸ Automatic Start and Stop Customize recording behavior to fit your needs: • Delayed recording start. • Automatic stop after a specified duration. • Stop recording when navigating to another page. • Stop after a configurable period of silence. ▸ Background Recording There's no need to keep the extension popup open. Pulse continues recording audio while you work on other tasks. ▸ Automatic Pauses During Buffering If playback temporarily stops due to buffering or connection issues, Pulse pauses recording and resumes when audio returns. Waiting time won't unnecessarily increase the length of your final audio file. ▸ Custom File Naming Create personalized filename templates using the tab title, website name, date, time, recording duration, and audio format. ▸ Record Audio from Local Files Pulse supports capturing audio from local audio and video files opened in Chrome using file:// URLs. ━━━ UNLIMITED RECORDING DURATION ━━━ Record anything from short audio clips to hours-long lectures, webinars, and live streams.
