Sonidata: UCS Field Recorder is built to help you maintain a professional audio archive on the go. Ensure every sound you capture is perfectly tagged, organized, and ready for high-level indexing the moment you get back to the studio. Designed for sound designers, field recordists, and audio professionals who demand precision from their mobile workflow. PROFESSIONAL CAPTURE & ROUTING Turn your device into a professional field recorder. With the newly introduced Audio Device Manager, select discrete input and output routing, apply hardware-aware format settings (48 khz 24 bit internally, and up to 192 kHz / 32-bit float, depending on the connected devices), and control input gain digitally or via your hardware interface. Monitor audio levels with the Record Ready monitor mode. Capture True Stereo or decode M/S microphones on the fly with per-mic persistence. UCS METADATA ON THE GO Say goodbye to renaming files back at the studio. Sonidata implements the industry-standard Universal Category System (UCS v8.2). Assign Category, FX Name, Vendor, Creator, Mic Perspective, Location, and more right from the field. Use the Voice Slate (Speech-to-Text) to dictate metadata hands-free, or create custom FX Name Templates to speed up repetitive tagging. POWERFUL BATCH EDITING & SYNC Manage massive recording sessions with ease. The new Calendar Filter Bar lets you drill down by date, while batch delete and bulk metadata pasting streamline your workflow. When you’re ready, your sessions—including embedded artwork and metadata—seamlessly sync to iCloud Drive, Google Drive, or Dropbox. SEAMLESS DESKTOP INTEGRATION Export comprehensive 29-column CSV reports fully compatible with industry-standard sound library management software. Use the companion desktop app, Sonidata Embed, to batch edit metadata and re-embed it into your WAV files without transcoding. KEY FEATURES • Broadcast-Standard Recording: 48 kHz 24-bit internally, anduUp to 192 kHz / 32-bit float WAV. • UCS v8.2 Compliant: Full metadata tagging (Category, FxName, Description, Mic Perspective, etc.). • Advanced Audio Routing: Discrete input/output selection, external interface support, and M/S decoding. • Visual Feedback: Live waveform-style stereo metering, colorized waveforms, and ActivityKit lock-screen tracking. • Cloud Sync: Automatic syncing via iCloud, Google Drive, and Dropbox. • External File Management: Import, edit, and organize audio recorded on other devices. • Seamless Export: ZIP exports grouped by date, paired with rich 29-column metadata CSVs. • Siri & Shortcuts Integration: Control recording hands-free via App Intents, Action Button, or Back Tap. • Secure & Private: All transcription and processing happen on-device. Your audio never leaves your device unless you export it. UPGRADE TO PRO Unlock the full potential of your field recording workflow with Sonidata Pro. Manage external files, create custom FX Name Presets, export in bulk, and unlock the Sonidata Embed desktop companion app for seamless macOS integration via secure offline pairing.

FAC Gravity AUv3 Plugin is a frequency shifter for creating Barberpole and Shepard style glissandos, spectral illusions, stereo rotation, chorusing, phasing, evolving echoes, infinite cosmic spaces, and all the combinations you’ll make. The plugin gives you two ways to process the audio source. In Stereo mode, each channel is shifted independently, with a Ratio control determining how closely their frequency shifts align. In Mono mode, FAC Gravity extends the internal quadrature processing to create a wide stereo image from the mono source. The frequency shift can move up or down, from subtle to more extreme spectral transformations. You can set the amount in Hz for classic Bode-style frequency shifting, make it follow your host tempo for rhythmic patterns, or even control it from MIDI notes for a more hands-on approach. A new dimension appears when you let the shifter feed back into itself with Spiral, a customizable loop with delay, blur, filtering, and different characters that shape how the sound circles, smears, interacts, and evolves over time. The result can range from bubbling textures to infinite sustained tones and noisy analog self-oscillation. Each character takes the feedback somewhere different. To dive deeper into new sonic dimensions, FAC Gravity comes with its own modulation module. The LFO, envelope follower, and flexible modulation matrix let you animate most parameters, from subtle evolving movements to complex, rhythmically reactive changes. You can even make the stereo field animate and rotate continuously by making the Width, Phase, and Pan parameters spin! You can shape the effect further by blending the processed signal with the original, while the optional limiter keeps the most extreme combinations in check. • Barberpole glissandos, spectral illusions, rotating stereo, evolving echoes • Dual Frequency Shifting, or Mono Shifting with Quadrature Stereo Widening • Organic Spiral Loop, from gentle feedback to pure analog self-oscillation • Integrated delay, diffusion blur, and independent low/high filtering • Modulation matrix, multi-source envelope follower • LFO with classic waveforms and random spline • Spinning modulation to rotate and animate the stereo field • Tempo-synced or MIDI-driven Frequency Shift, LFO, and Delay • Dry/Wet mix, optional limiting, and goniometer visualization • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro The documentation is available at fredantoncorvest.com/FAC_Gravity.html This is an AUv3 Effect and requires a compatible host to work The in-app purchases are for tipping only, the app is fully functional without them

Verdict

The call

The clearest difference is price: Sonidata at Free against FAC Gravity's $9.99. FAC Gravity's advantage is rating (4.9 vs 4.0) and ratings volume (7 vs 1). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
