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.

  • Frequency shifting, blurring, and filtering
  • Internal tone generator and MIDI input
  • Up to eight voices of polyphony
  • Detailed control over resonance parameters
  • Interactive 3D spectrogram visualization
  • Freeze and Kill controls
Read full description

By converting audio into the spectral domain, BLEASS Spectral Resonator can shift, blur, filter, and restructure the frequency content of any sound before generating resonances. When blended with the source signal, this adds a controllable layer of pitch and timbre. Used fully wet, it produces rich and complex spectral textures. Resonances can be generated from an internal four-voice tone generator or directly from incoming MIDI notes. With up to eight voices of polyphony, glide, pitch bend, and up to 256 harmonics per voice, BLEASS Spectral Resonator can be played from MIDI to create tuned harmonic resonances and evolving spectral textures. Intuitive controls provide detailed manipulation of the resonator behaviour, including unison, detuning, harmonic stretching, density, damping, decay, and harmonic filtering. Harmonics can be restricted to even or odd series, while spectral shifting and blurring further reshape the resulting resonances. A spectral-domain filter lets you select the frequency range used to excite the resonators. The interactive 3D spectrogram visualises resonator activity over time while also providing direct control over the spectral filter. BLEASS Spectral Resonator also includes Freeze and Kill controls for holding or clearing active resonances. Designed to combine deep spectral processing with an accessible interface, it opens new possibilities for harmonic, rhythmic, and dynamic sound design, including inharmonic or atonal material such as drums. BLEASS Spectral Resonator is also available for Desktop. Find more information here: http://www.bleass.com/spectral-resonator
