Node-based batch audio processing

A visual batch processor for serious audio workflows.

Build visual DSP and plugin chains, audition the processed result, then render repeatable jobs across large file sets.

Batchy Workspace
macOS + Windows GUI + CLI VST3 AU (macOS)

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 without building a DAW session first.

Built for repeatable audio work

For audio teams who need one approved chain applied consistently across albums, game assets, episodes, stems, and delivery folders.

One approved chain Entire folders Clean naming CLI handoff
Mastering Albums, refs, revisions

Lock the chain, then render the release.

Dial in EQ, dynamics, loudness, and output formats once, then apply the approved chain to masters, instrumentals, client refs, and revision passes without rebuilding the session.

  • Keep tone and loudness consistent across every track
  • Generate master, instrumental, and preview deliverables from one preset
Game Audio Assets, loudness, naming

Turn asset drops into shippable files.

Point Batchy at UI sounds, ambiences, weapons, VO, or music stingers and run cleanup, loudness, naming, and format passes without writing a custom script for every delivery.

  • Render folders in parallel 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

Make every episode land at the same standard.

Build a cleanup chain with gating, compression, EQ, and LUFS normalization, then run it across new episodes or a full back catalog without opening each project by hand.

  • Normalize stereo and mono episodes to platform-ready loudness targets
  • Apply the same cleanup pass across seasons in parallel
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 stems, apply room matching, and render format-specific deliverables across a scene, reel, or full asset folder without babysitting every export.

  • 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.

No credit card. No commitment. Full access for 30 days.

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 exact chain in every run

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 Create every deliverable in one run

Use multiple output nodes for masters, stems, and previews, then override format or bit depth per output when a delivery needs variants.

Master.wav | Stems/*.flac | Preview.mp3
Naming Control Keep folders and filenames predictable

Use filename templates and metadata tokens so project, client, version, and deliverable names land in the right folder without manual renaming.

$project/$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 Hit delivery specs without a second pass

Set LUFS, peak, or RMS targets alongside bit depth, dither, tail rendering, and output format controls before exporting WAV, AIFF, FLAC, MP3, or OGG.

-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 from real delivery work

Batchy started as an internal tool for a working audio engineer who needed to normalize, reformat, and verify thousands of game audio assets without rebuilding the same chains every milestone.

Common questions

Trial What happens after the 30-day free trial?

After 30 days you can still open Batchy, browse presets, and view your processing chains. Batch processing and file export lock until you purchase a license. Your presets and settings are never deleted.

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 11+ (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, OGG, M4A, WMA, CAF. Output: WAV (16/24/32-bit), AIFF, FLAC, MP3, OGG. 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.

Try the full workflow for 30 days

No credit card. After 30 days, you can still open and view presets. Purchase to unlock processing and export.

What Batchy can replace
