Dynamic elements
Place dynamic placeholder clips. Each holds N audio variants. On render, every combination becomes a finished WAV.
*Multiple dynamic elements require BatchCast Pro.
For podcast & broadcast production
Batch Audio Workflow Editor
Render hundreds of broadcast-ready audio variants from one template — in seconds.
BatchCast is the desktop app for multi-track audio with dynamic placeholders. Multi-host × content × sponsor — every possible combination, rendered automatically.

Why BatchCast exists
Anyone producing weekly podcast or broadcast content knows the pattern: your time belongs in the concept, the writing, the edit — not in the export workflow.
1
Weekly production is repetitive.
Same beds, same intros, only the voiceover and content change. Yet most studios still rebuild every episode by hand.
2
Manual exports are error-prone.
Wrong file on the wrong lane, a forgotten variant, an untrimmed bed. At 50 renders per week, a single mistake gets expensive.
3
Good tools are missing.
Classic DAWs are built for mix & master — not for template-based multi-variant audio. BatchCast closes that gap.
What BatchCast is used for
Weekly podcast
Intro + bed + outro are fixed. Per episode you only drop the voiceover — BatchCast builds the finished show. With LoopCut the bed ends precisely on the right beat, every time.
Saves arranging and render time on every episode
Multi-host trailer
Two hosts × three content variants = 6 outputs. Hosts are coupled in one group (intro+outro from the same voice), content rotates in a second group.
Consistent — no forgotten combinations
Modular radio content
Station jingles, prepared moderation slots, promotion drops. Build templates and work with CLI command-line automation to have the right variants ready at the right time.
All from the command line, ready whenever you want
What makes BatchCast different
Six core features you won’t find combined in any DAW.
Beat-aware LoopCut
The BPM analyzer tries to detect the tempo, and the music is trimmed to the length of the dynamic element. Sounds human, not edited.
Mute groups
Audio elements can be assigned to mute groups. Within the same group, a later element ends the previous one — e.g. to place an outro element.
Terminal — BatchCast
C:\>
"C:\Program Files\BatchCast\BatchCast.exe"
--batch
--project="\PathToProject\DemoSession.bcp"
--input="\PathToProject\inputs"
--output="\PathToProject\render"
--audio-root="\PathToProject\audio"
✓ Batch render complete — 6 variants exported
CLI batch mode
Headless rendering from the command line. Watch folders, cron jobs, nightly builds. The project is the template; audio is fed in via the input folder.
*CLI batch mode requires BatchCast Pro.
Flexible file naming
A token-based name builder: project name, variant index, date, group names. Hundreds of renders get clean, unique filenames automatically — no manual renaming.
Per-track FX + master
High-pass, low-pass, 3-band EQ, compressor, limiter — per track. Plus master limiter and voice presets that just work.

chained to episode end bed ends on beat
A music bed with intro runs under the episode — and thanks to LoopCut it ends exactly on the music bed’s end, not hard-cut or faded out. Per episode you just drop the finished content into the dynamic element.
Need a fixed outro instead? Chain an end element to the end of the episode — it stays linked automatically, no matter how long the episode runs.
Step by step in BatchCast
- 1 Drag the intro/music onto the first track and create a dynamic element on track 2.
- 2 Drag all episodes onto the dynamic element on track 2.
- 3 Right-click the intro/music. Under “Beats & Snap”, enable LoopCut.
- 4 Check LoopCut; adjust the markers and BPM if needed.
- 5 Click “GO – Render” to export all episodes.
5 episodes → 5 finished WAVs in under a minute.

Imaging Bed
O1 Vocal

O2 Moderation

Moderation chained — follows the vocal’s end directly, whatever its length
→ O1 · 2 „The newest hits" O2 · 2 „Hot and new — the freshest sounds" 2 × 2 = 4 variants
An imaging bed for your morning show, two variant groups you can combine freely — BatchCast Pro renders every combination automatically.
Step by step in BatchCast Pro
- 1 Drag the imaging/jingle onto track 1, switch the timeline to BPM and set the project BPM.
- 2 Create a dynamic element on track 2, placed at the beat-correct entry point of the vocal. Drag all vocal variants onto the dynamic element.
- 3 Add another track, create a second dynamic element and place it right after dynamic element 1. Right-click the element and switch it to order 2.
- 4 Link the second dynamic element to the end of the first one via its properties. This keeps the second element’s relative position constant — it shifts dynamically when the first element has different lengths.
- 5 Fill the second dynamic element with audio and click “GO – Render” to export all variants.
2 × 2 = 4 finished imaging variants — rendered automatically.
⭐ BatchCast Pro · CLI
Modular content: build the template once, then just fill it
show.bcp — project template
input/
├─ audio/ — packaging elements
├─ stationclaims/ — claim variants
└─ dailycontent/ — daily content
$ batchcast --batch --project=show.bcp --input=input/ --output=render/
# cron · daily at 03:00
With BatchCast Pro you build the template once that reliably produces modular content. After that, your automation only fills the subfolders with the fresh audio — a cron job kicks off the run, and the finished content is ready. No opening the app, no clicking.
Step by step in BatchCast Pro
- 1 Design the template in the BatchCast GUI and set the identifiers of the dynamic elements — e.g. “sing” or “dailycontent”.
- 2 Consolidate the project via the menu and move it, with all audio, to a new location.
- 3 Fill the element folders daily or weekly with the new audio and process them via the batch command line.
Tip: When consolidating, BatchCast creates an HTML help file that already contains the matching command-line commands for Windows and Mac.
Set it up once, and production runs fully automatically — day after day.
