Recording a podcast episode in multiple segments is common — a strong intro, the main interview, an ad read, and an outro are often recorded separately. Merging them into one continuous episode file before editing is a straightforward task that does not require a full DAW or audio editor.
The browser audio merger handles this specific workflow: upload your segments, drag them into episode order, click Merge, and download the combined MP3. For podcasters who handle their own audio assembly before sending to an editor, this removes the need to open Audacity just to join files.
Common Podcast Recording Scenarios That Need Merging
Podcasters encounter file-merging needs regularly:
- Multi-part interviews: Recording an interview over two sessions, or pausing and resuming (which creates a new file in most recording software). Both segments need to be one continuous file before editing.
- Pre-produced elements: An intro jingle or show open recorded separately, the main interview, a mid-roll ad read, and an outro combined into the final episode order.
- Split remote recordings: Remote recording platforms like Riverside, Zencastr, or Squadcast provide separate tracks per guest. Sometimes you need to join sequential portions of a guest's track from a long recording session.
- Chapter-by-chapter assembly: Educational or narrative podcasts where each chapter is recorded as a separate file and assembled into a full episode.
- Zoom/Teams recording segments: Zoom automatically splits recordings at certain file size limits. Joining these back together before editing restores the full session.
Best File Order for Podcast Assembly
A typical podcast episode structure and the order to arrange segments:
- Pre-roll ad or sponsor message (if running at the start)
- Intro music or show open (jingle, theme, host intro)
- Main content (interview, solo episode, panel discussion)
- Mid-roll ad (if applicable — usually near the midpoint of the episode)
- Continuation of main content
- Outro (thanks, CTA, next episode preview)
- Outro music
Use the drag handles in the merger to arrange your files in this order before clicking Merge. The merged file will play in exactly the sequence you set.
Note: the mid-roll ad placement (step 4) depends on episode length. For a rough assembly before sending to an editor, it is fine to put the ad segment roughly in the right position — the editor will adjust timing anyway.

The merged output is a rough assembly — all segments joined end-to-end as a single MP3. This is useful as a starting point for editing or for simple episodes that do not need extensive post-production.
What the merged file is:
- A single MP3 file with all your segments in sequence
- 192kbps quality — acceptable for podcast distribution
- Ready to upload directly to a podcast host if no further editing is needed
- A starting point for your audio editor if editing is needed
What the merged file is not:
- Volume-normalized — different segments recorded at different levels will have different volumes in the merged file
- Edited for content — mistakes, dead air, and filler words are still present
- Mixed or EQ'd — no audio processing is applied
- Crossfaded — transitions between segments are hard cuts, not fades
For final episode production, most podcasters will want to process the merged file further. For quick assembly before sending to an editor, or for simple episodes with consistent recording quality, the merged file is often ready to publish.
Audio Formats for Podcast Recordings
Podcast recording creates files in various formats depending on the tool used:
| Recording Source | Typical Format | Merger Compatibility |
|---|---|---|
| Riverside.fm | WAV (lossless, local) or MP4 | WAV supported directly |
| Zencastr | MP3 or WAV | Both supported |
| Zoom (cloud) | M4A or MP4 | AAC/M4A supported |
| Zoom (local recording) | MP4 with separate audio track | Extract MP3 first if needed |
| GarageBand (Mac) | AIFF or M4A | AAC/M4A supported |
| Audacity | WAV or AIFF (export) | WAV supported |
| Voice Recorder (phone) | MP3 or M4A | Both supported |
If your files are in M4A format (common from Zoom and GarageBand), the merger handles them as AAC — just upload and merge normally. The output will be MP3.

Open Free Audio MergerFrequently Asked Questions
Can I merge podcast audio without Audacity?
Yes — the browser-based audio merger joins podcast segments without installing Audacity. Upload your files, drag into episode order, click Merge, download the combined MP3. For basic assembly without editing, no DAW is needed.
Is 192kbps MP3 good enough quality for a podcast?
Yes. Most podcast hosting platforms recommend 128-192kbps MP3 for voice content. 192kbps is the upper end of the recommended range and sounds clean for spoken audio. Audiophile music podcasts sometimes want higher, but for voice, 192kbps is more than sufficient.
Can I merge a WAV intro with MP3 interview segments?
Yes — the tool accepts different formats in one merge. Combine WAV, MP3, OGG, FLAC, and AAC files in any combination. They all merge into a single MP3 output.
How do I get a Zoom recording's audio as a file I can upload?
Zoom cloud recordings include a separate audio-only file (M4A format) alongside the video. Download the M4A file from your Zoom cloud recordings page. For local recordings, look in Documents/Zoom on your computer — Zoom saves both an MP4 and a separate audio file (.m4a) for most recordings.
