Podcast Recorder helps you capture a complete podcast-ready episode in a simple browser flow: record your main audio, optionally add an intro clip and outro clip, and export a single stitched MP3 you can share anywhere. The tool uses your browser’s microphone recording for the main take, then sends your audio parts to a public backend endpoint powered by FFmpeg to concatenate the clips and encode a consistent MP3 output. You can also set optional MP3 metadata (title, artist, album, year, genre, and a short comment) so the exported file is labeled cleanly in players and file managers. A Sample Input button loads real audio clips so you can test the full record → stitch → download pipeline without touching your microphone. For creators who want a faster publishing workflow, an optional AI Assistant (runs only when you click) can turn your outline into structured show notes, chapters, and hashtags.
Note: AI can make mistakes, so please double-check it.

Yes. Upload an optional intro clip and outro clip, then click Build episode MP3. The backend stitches the clips in order: intro → main → outro.
Yes. You can optionally set title, artist, album, year, genre, and a short comment. The backend writes these fields into the exported MP3 so it’s labeled cleanly in players.
Stitching and MP3 encoding are handled by a stateless backend service using FFmpeg for speed and reliability. The result is returned as a downloadable MP3.
When you click Generate show notes with AI, the tool sends your outline to a secure backend endpoint. It returns structured show notes, chapters, and hashtags to speed up publishing.
Open the Podcast Recorder, select your microphone, click Record, and allow permission when prompted. When you stop, you can preview the main take and build a single MP3 for download using the backend stitch-and-export step.
Upload an intro clip and outro clip in the Episode parts section, then click Build episode MP3. The backend concatenates the clips in order (intro → main → outro) and returns one downloadable MP3.
After recording (or loading sample audio), click Build episode MP3. The backend uses FFmpeg to encode a compatible MP3 and returns a download link with a suggested filename.
Fill in the MP3 metadata fields (title, artist, album, year, genre, comment) before you build the episode. The backend writes those fields into the exported MP3 so players can display them.
Paste your outline into the AI Assistant box and click Generate show notes with AI. The request runs only on click and returns a structured title, description, chapters, bullets, and hashtags you can copy into your publishing workflow.

Learn what this tool does, when to use it, and how it fits into your workflow.
A podcast episode usually fails at the simplest moment: you have a good take, but turning it into a single, shareable file takes extra steps. Podcast Recorder is a lightweight workflow to record audio in the browser, optionally add an intro and outro, and export one stitched MP3 with clean metadata. It is designed for people who want an online podcast recorder that feels like a quick utility rather than a full studio app.
This tool follows a straightforward flow: Input → Processing → Output. You record your main segment (or load a sample), optionally attach intro/outro clips, and then the backend builds a single MP3 in the correct order. The output is meant for quick publishing, sharing, or archiving.
Most creators don’t struggle to hit “record”—they struggle with the last mile: turning multiple clips into one consistent file. The must-have promise here is simple: stitch intro, main, and outro into a single MP3 in one click. This solves the common pain of “I have the pieces, but I need an episode file now,” especially for solo shows and quick announcements.
If you only need raw microphone capture, you can use Audio Recorder. If you already have multiple clips recorded and you only want sequential joining, Audio Joiner is a good companion. After export, if your loudness is inconsistent, Audio Normalizer can help you normalize levels. If you want to refine tags after you download, Audio Metadata Editor lets you edit title/artist/album fields. And if your recording has steady ambient sound, Background Noise Remover can reduce it before you publish.
Even a simple record podcast audio online workflow benefits from a few habits:
Metadata is optional, but it’s valuable for a podcast episode MP3 export workflow where files travel between devices. The tool supports a compact set of fields:
| Field | What to put there | Why it helps |
|---|---|---|
| Title | Episode name | Readable filenames and player labels |
| Artist | Host or show name | Consistency across your catalog |
| Album | Podcast name or season | Grouping in libraries |
| Year | Publication year | Sorting and archiving |
| Genre | Podcast (or a broad category) | Filtering in some players |
| Comment | Short note (guest, topic, disclaimer) | Extra context without changing content |
Publishing is more than an audio file. Many creators also need a title, a short description, chapters, and a set of bullets for show notes. The optional AI Assistant is a premium, gated feature that runs only when you click. You paste an outline or rough notes, and it returns structured show notes that you can copy into your publishing workflow. This is useful when you want AI generated podcast show notes without rewriting everything from scratch.
Creators often look for practical workflows such as record podcast in browser, online podcast recorder, podcast recorder with intro and outro, stitch podcast intro and outro, export podcast MP3, podcast MP3 metadata tags, add title and artist to MP3, record audio with pause and resume, download podcast recording as MP3, browser based podcast recording, podcast episode MP3 export, podcast intro outro stitcher, create podcast show notes, AI generated podcast show notes, podcast chapter timestamps, and how to record a podcast episode online.
