Where repeat audio work breaks down
- Rebuilding the same chain for every delivery
- Maintaining scripts that drift from the approved sound
- Checking loudness, naming, and formats after the fact
- Exporting large file sets one pass at a time

Feature demos
Load and queue files fast
Drop files in, browse folders, and audition the chain before rendering.
Choose a starting point
Start with the work you repeat.
Pick a workflow, then shape one chain you can reuse across the next delivery.
Your podcast chain. A whole batch of episodes.
Audition your chain, save the setup, and render named files across an episode batch.
See the podcast production workflow Music productionGet the sound right. Then run the batch.
Shape your audio, save the chain, and render named WAV and FLAC outputs across your project.
Watch the music demo Sound designOne source set. Multiple sound treatments.
Route one source set through named treatments, then reuse the graph across your library.
See the sound design workflowBuilt for repeatable audio work
For audio teams who need to audition processing, render named outputs, and reopen the setup across albums, game assets, episodes, supplied stems, and delivery folders.
Mastering Albums, refs, revisions
Audition the chain, then render the release.
Audition your EQ, dynamics, and plugins, then save the graph with your loudness and output settings for supplied mixes, instrumentals, client refs, and revisions.
- Reuse your chosen processing and check each track before delivery
- Process supplied mixes, instrumentals, and alternate versions with one saved preset
Game Audio Assets, loudness, naming
Prepare asset drops for delivery.
Point Batchy at UI sounds, ambiences, weapons, VO, or music stingers, then check cleanup, loudness, naming, and format choices before rendering the source set.
- Render a source folder in a batch when the asset count gets large
- Use path and filename tokens to keep export trees predictable
Sound Design Textures, variants, transformations
Design the sound once, then make the variations.
Build chains for pitch, distortion, convolution, filtering, routing, and texture work, then audition the result live or stamp the treatment across an entire source set.
- Combine native DSP and external plugins in one graph
- Compare waveform, spectrogram, and processed views before committing
Podcasting Cleanup, levels, seasons
Process an episode batch with your saved chain.
Build a chain with gating, compression, and EQ. Audition representative recordings, then save the graph with your loudness and output settings for new episodes or a back catalog.
- Set loudness targets to match your delivery brief
- Reuse saved processing and naming across a season or back catalog
Automation GUI presets, CLI jobs
Design in the app, render in the pipeline.
Build and verify a preset visually, then hand the same graph to command-line jobs, scripted render sessions, or watch-folder workflows when the work needs to repeat.
- Use JSON render reports and fail-fast options in automation
- Keep one preset structure across manual and headless runs
Film & Post Stems, surround, deliverables
Move from mix assets to delivery formats.
Convert channels, prep supplied stems, apply room matching, and render format-specific outputs across a scene, reel, or full asset folder. Check the exports against the delivery brief.
- Handle spatial panning and channel conversion up to 7.1.4
- Use convolution reverb IRs to match rooms across scenes
Run it on your own file set.

The full toolkit
Build one graph, audition the processed result, then reuse the same .batchyfx preset in the app, in batch jobs, or from the command line.
Saved Signal Chains Reuse the saved chain across runs
Save drag-and-drop processing graphs as .batchyfx presets you can reopen, share, and run across macOS, Windows, batch folders, and CLI jobs.
my-chain.batchyfx
Live / Processed Preview Check the processed result before export
Flip between live playback and the processed preview so waveform and spectrogram changes are visible before you commit the export.
Live | Processed | Waveform | Spectrogram
Multi-Output Presets Render several named outputs in one batch
Use multiple output nodes for the versions you need, then set format or bit depth per output when a delivery needs variants.
Mix_44k.wav | Mix_48k.flac | Archive.aiff
Naming Control Keep folders and filenames predictable
Use filename templates and metadata tokens to keep project, client, version, and deliverable names predictable.
$project/$deliverable/$filename_$version
Plugin + DSP Hybrid Mix native DSP with your plugins
Combine external VST3/AU processors with built-in EQ, dynamics, distortion, pitch shift, delay, convolution, reverb, and routing in the same graph.
VST3/AU + EQ + dynamics + routing
Loudness + Delivery Set loudness, formats, and filenames before rendering
Set LUFS, peak, or RMS targets alongside bit depth, dither, tail rendering, and output format controls before exporting your files. Check the rendered files against your delivery brief.
-14 LUFS | 16-bit WAV | dither | tail render
CLI + Automation Run the same preset from scripts
Use the same preset in terminal, CI, remote render, and watch-folder workflows with JSON reports, dry runs, fail-fast behavior, and per-output overrides.
batchy --batch-process --input ./audio --preset delivery.batchyfx --render-report out.json
Made for sound design, too
Chain pitch shifting, convolution reverb, distortion, band splitting, and filtering into reusable treatments. Audition them in real time on one file, compare waveform and spectrogram views, then render the same chain across the full source set.
Built on 20+ years of sound design experience
Batchy was created to solve the recurring processing and delivery challenges its developer has encountered over more than 20 years as a professional sound designer.
Common questions
Buy Is there a free trial?
No. Batchy does not offer a free trial to new users. The macOS and Windows installers are free to download, but a purchased license is required before you can use the app. Install it, then enter the license key from your purchase email on first launch. Every purchase is backed by a 30-day money-back guarantee, so you can buy with confidence.
Owners I bought Batchy — where do I download and activate?
Your purchase email from Lemon Squeezy includes your license key and the download link. Visit the Downloads page for the macOS or Windows installer and activation steps, then enter your key on first launch. One license covers two machines (macOS + Windows).
Plugins Can I use my existing VST3 and AU plugins?
Yes. Batchy hosts VST3 plugins on macOS and Windows, plus Audio Unit (AU) plugins on macOS. Your plugins appear in a separate Plugins tab, and you can mix them with Batchy's native audio nodes in the same graph.
System What are the system requirements?
macOS 12+ (Intel and Apple Silicon) or Windows 10/11 (64-bit). Any machine that can run a modern DAW will run Batchy comfortably. Batch processing scales across all available CPU cores.
License How many computers can I install it on?
One license covers two machines — for example, a studio desktop and a laptop. Both macOS and Windows are included. No dongles or hardware keys.
Pricing Is this a subscription?
No. One-time purchase. You pay $149 once and get the full application plus free updates within the current version. No recurring fees, no annual renewals, no feature tiers.
Commercial Can I use Batchy for commercial and client work?
Yes. Your license covers personal and commercial use. No royalties on processed output, no per-project fees, and no restrictions on how you use the files Batchy produces.
Formats What audio formats are supported?
Input: WAV, AIFF, FLAC, MP3, and OGG, plus platform codecs where available. Output: WAV (16/24/32-bit), AIFF, and FLAC. MP3 and OGG output availability depends on your installed version. Sample rates from 8 kHz to 192 kHz.
Security Is Batchy safe to download?
Batchy is code-signed and notarized by Apple on macOS, and signed with Microsoft Azure Trusted Signing on Windows. Every release is submitted to VirusTotal and ships with SHA256 checksums.
