What is Recavio STUDIO?
Recavio STUDIO is a web-based audio editor designed specifically for podcast editing. After recording a podcast in a Room, separate audio tracks are automatically created for each participant. The editor allows you to cut, move, mix, and ultimately export these tracks into a final MP3 or WAV file.
Non-destructive editing
Split, cut and keep portions of clips. The original audio is never modified — you can always revert.
Track mixing
Adjust the volume of each track, mute or solo individual participants.
Undo / Redo (200 steps)
Full change history. Go back anytime or restore the original state of the recording.
Export to MP3 / WAV
The final mix is processed on the server. Download the result in professional quality (MP3 320 kbps or WAV PCM 16-bit).
Editor interface overview
The editor is divided into 6 main zones. Below you will find an annotated diagram with an explanation of each part:
Managing audio tracks
Each recording participant has their own track with a unique color. Tracks are displayed in the sidebar on the left and their clips appear in the corresponding rows on the timeline.
Mute
Click the button. A muted track will not be included in playback or export. Click again to unmute.
Solo
Solo mode plays only this track. All others will be automatically muted. Ideal for checking a single voice.
Volume
Use the slider below the buttons to set the track volume (0–100%). Changes take effect immediately in playback and export.
Working with the Timeline
The timeline is the main workspace of the editor. At the top is the ruler with time markers, below it are track rows containing individual clips.
Clip parts
Grab bar (top strip) — displays the track name and duration. Dragging the grab bar moves the clip along the timeline. Waveform (clip body) — visual representation of the audio. Clicking on the waveform selects the clip.
Playhead (playback position)
The red vertical line on the timeline is the playhead. It determines the current playback position and the position for the Split operation.
Click on the ruler
Click anywhere on the ruler at the top of the timeline to move the playhead to that position.
Drag the handle
Drag the red dot (handle) on the ruler for smooth playhead positioning.
Keyboard navigation
Press Home to jump to the start, End to jump to the end. Press G to jump to the start/end of the selected clip.
Zoom
Zoom controls how much detail you see on the timeline. Range is from 0.08x (maximum zoom out) to 8x (maximum zoom in).
Ctrl + +
Zoom in
Ctrl + −
Zoom out
Ctrl + 0
Fit to screen
Zoom can also be controlled via the and buttons in the bottom bar, or with the mouse wheel while holding Ctrl.
Horizontal scrolling
To scroll horizontally along the timeline, hold Shift and use the mouse wheel.
Timeline limits
The editor defines two limits on the length of the final content:
Soft limit — 2× original length
A yellow marker is displayed. When exceeded you will receive a warning, but you can still move clips.
Hard limit — 3× maximum
Red marker. Clips cannot be moved beyond this boundary. If content exceeds the hard limit, export is not possible.
Clip selection methods
Clip selection is key for editing operations. Selected clips are highlighted (brighter color, thicker border) and available operations appear in the action bar.
| Action | Control | Description |
|---|---|---|
| Select clip | Click on waveform | Click on the clip body to select it. Click again to deselect. |
| Add to selection | Ctrl + Click | Adds or removes a clip from the current selection (toggle). |
| Range | Shift + Click | Selects all clips between the first selected and the just-clicked clip (inclusive). |
| Rectangle selection | Drag mouse on empty space | Draws a selection rectangle. All clips the rectangle passes through will be selected. |
| Select entire track | Ctrl + Click on empty row | Selects all clips in the given track at once. |
| Select all | Ctrl + A | Selects all clips across all tracks. |
| Deselect | Esc | Cancels the current selection or closes an open panel. |
Editing operations
The editor supports three basic editing operations and clip movement. Every operation is immediately reversible via Undo.
Split
Select clips
Click on the clip(s) you want to split.
Position the playhead
Click on the ruler or drag the playhead to the position where you want to split.
Press S or click Split
The clip splits into two separate parts at the playhead position. If either part would be shorter than 0.5 s, the split will not be performed.
Cut
Removes selected clips from the timeline. Audio in those clips will not be included in playback or export.
Control: Select clips → Ctrl + X or click the Cut button in the action bar.
Keep
The opposite of cut — keeps only the selected clips and removes all others on the same tracks. Clips on other tracks remain untouched.
Control: Select clips → Ctrl + K or click the Keep button in the action bar.
Moving clips (Drag)
Grab the clip grab bar
Click and drag the top strip (grab bar) of the clip. The clip will start moving along the timeline.
Moving multiple clips
If you have multiple clips selected, grabbing the grab bar of one of them will move all selected clips at once.
Collisions are handled automatically
Clips do not overlap — the editor automatically pushes colliding clips aside. A clip also cannot exceed the hard limit.
Undo / Redo and Restore original
The editor stores up to 200 steps of change history. Revert changes with Ctrl + Z (Undo) or repeat them with Ctrl + Y (Redo).
The Restore original button in the toolbar resets all tracks to their original state — all cuts, moves and volume changes will be discarded. A confirmation dialog appears before execution.
Playback and preview
The editor plays audio directly in the browser using the Web Audio API. Playback respects volume, mute and solo settings.
| Control | Shortcut | Description |
|---|---|---|
| Play / Pause | Space | Starts playback from the current playhead position. Press again to pause. |
| Jump to start | Home | Moves the playhead to 0:00. |
| Jump to end | End | Moves the playhead to the end of content and stops playback. |
| Seek bar | Slider in bottom bar | Drag the slider for quick navigation to any position. |
| Snap to clip | G | If a clip is selected, the first press jumps to its start, the second to its end. |
Saving the project
The editor automatically saves your work to the server. Saved data includes: clip positions, track settings (volume, mute, solo), playhead position and zoom level.

Practical tips and frequently asked questions
Typical podcast editing workflow
Play and identify
First, play through the entire podcast. Listen and note the times of parts you want to cut (pauses, mistakes, tangents).
Split at key points
Position the playhead at the start of the unwanted part. Select clips (Ctrl+A for all tracks) and press S. Then split similarly at the end of the unwanted part.
Cut unwanted parts
Click on the clip(s) between the splits and press Ctrl+X.
Move and fine-tune
If there is a gap between clips, grab the grab bar and move clips closer together.
Set volume and export
Fine-tune track volumes in the sidebar. When satisfied, click Export.
Frequently asked questions
What happens when I close the browser?
The project is automatically saved every 30 seconds. If you made changes and did not close the tab too quickly, your work will be saved. On next editor launch, the last saved state will be loaded.
Can I lose the original recordings?
No. The editor works non-destructively. The original audio files are never modified. You can always click "Restore original" and go back to the beginning.
Why can't I edit during playback?
Editing operations require stopping playback to maintain audio stream consistency. Press Space to pause and then perform the edit.
What do the yellow and red lines on the timeline mean?
The yellow line is the soft limit (2× original length) and the red is the hard limit (3× maximum). If clips exceed the hard limit, export is not possible.
Export takes too long / is queued
Export takes place on the server. If the server is busy with other exports, your export waits in queue. The "Export is queued" dialog closes automatically when processing begins.
Can I rename the podcast?
Yes. Click on the podcast name in the toolbar or the icon next to it. Enter a new name (3–20 characters, only letters, numbers and spaces) and confirm with Enter.
Supported browsers
The editor uses Web Audio API and modern CSS. We recommend Chrome, Firefox or Edge in the latest version. Safari works but may have limitations decoding certain audio formats.
Language change
The editor supports Slovak and English. Switch the language via the button in the top right corner of the header. If you have unsaved changes, a confirmation dialog will appear — changing the language reloads the page.
