App summary
Caustic Mastering is a premium mobile mastering app from Single Cell Software that brings professional finishing tools to phones and tablets. It’s designed for artists and producers who want to polish mixes and prepare final masters without being tied to a desktop workstation.
What it offers
- Six-band parametric EQ for surgical frequency control.
- A 10-band graphic EQ for broad tonal shaping.
- Stereo image enhancement and an audio exciter to add width and presence.
- RMS and three-band compression to even out levels and glue mixes.
- A signal clipper and a look-ahead limiter to tame peaks and prevent distortion.
File compatibility and formats
The app handles common delivery formats, including 32-bit WAV, OGG, MP3, and FLAC (availability depends on the source). This range helps maintain compatibility with other DAWs, apps, and streaming/upload platforms.
Workflow and use case
Mobile devices have become powerful enough to support mixing and mastering on the go, and Caustic Mastering is a practical choice if you need to finish tracks away from a laptop. Its controls are focused on final-stage processing: EQ, dynamics, stereo work, and peak control—everything needed to prepare a master for export.
Known shortcomings
One limitation to be aware of is the lack of support for higher sampling rates such as 96 kHz or 192 kHz, which some users and high-end workflows require. Otherwise, the app covers most typical mastering needs for mobile use.
Alternatives to consider
- Caustic 3 Free — a related option that may fit hands-on production and sketching needs.
- BandLab — a cloud-based alternative with collaborative features and integrated tools.
Recommendation
If you need a capable, mobile-first mastering tool with a wide set of processors and format support, Caustic Mastering is worth trying. It won’t replace high-end desktop suites for every scenario, but for most mobile workflows it provides the essential tools to clean up and finalize tracks. Give it a test run to see how it fits your process.
