StudioEditor.io

StudioEditor.io is a free, browser-based audio editor designed for podcasters, interviewers, and content creators. You can record directly in your browser, import audio, cut and arrange clips on a timeline, mix speech with music and effects using AutoDuck, and export finished audio — all without installing any software. Basic editing and exporting are free; a free account unlocks recording in the full editor, project saving, and exports. AI-powered features like speech enhancement, auto tightening of long pauses, transcription, subtitles, and summarization use a credit system — new accounts get 60 credits (one credit per processing minute).

The tool stands out for its focus on speed and simplicity. Auto Tighten Speech automatically shortens dead air while keeping conversations sounding natural, not choppy. Auto Enhance polishes voice recordings with balanced levels and clarity. The AutoDuck feature manages background music ducking automatically, with extra controls for experienced users. Transcription and subtitle exports come in SRT, VTT, PDF, Word, and plain text — all editable in the browser. You can also generate podcast episode summaries and SEO keywords ready to publish.

StudioEditor.io is ideal for podcasters who want a quick, no-download editor, interviewers cleaning up dialogue, educators creating audio lessons, and news media preparing clips for release. If you need professional-grade editing without the complexity of desktop software — and don't mind using credits for the AI extras — this is a solid, accessible option.
