Mac
Professional SMPTE timecode generator for Apple Silicon Macs. Generate up to 99 files in batch operations for film, broadcast, and audio production.
Retro LTC Pro generates SMPTE compliant Linear Timecode files and provides real-time LTC output for professional film, broadcast, and audio production workflows on Apple Silicon Macs.
The application features powerful batch generation capabilities, allowing you to create up to 99 LTC files in a single operation. Configure start timecode, file length, and offset between files to generate complete timecode series for multi camera shoots, extended productions, or equipment calibration workflows. Batch files are automatically compressed into zip archives for efficient transfer and storage management.
Create precise LTC audio files with all standard frame rates including 24, 25, 23.976, 29.97 Drop Frame, 29.97 Non Drop Frame, and 30 frames per second. Configure start timecode, duration, and professional options including 2-pop sync tones, reference audio, and 14kHz low pass filtering for equipment compatibility.
Files are saved using your selected sample rate (48 kHz or 44.1 kHz) and bit depth (24/16/8-bit) as mono WAV, with smart file naming that encodes all parameters for organization and workflow integration. Individual files or complete batch series can be generated with progress tracking and resource management.
Live LTC output requests your selected sample rate and falls back to the interface hardware rate if the device rejects the request; the realtime path runs at 16-bit and the UI shows the actual format in use. Custom Live LTC mode allows user defined start and end times with full transport controls including play, pause, resume, stop, and loop functions. The cue list feature lets you build and manage multiple timecode ranges: add cues with custom names, reorder by drag-and-drop, delete or clear all, and export individual cues with cue names prefixed in filenames. Playback is cached to prevent glitches, auto-advances with a 1-second gap between cues to eliminate audio thumps, and background rendering shows a spinner indicator while cues are being prepared.
The application is optimized for Apple Silicon Macs, taking advantage of the performance capabilities of M series processors for fast generation of large batch series and extended duration files. The native Mac interface provides efficient workflow integration with standard macOS file management and sharing capabilities, including an "Audio Output" picker in the app menu for selecting your interface.
Technical specifications include SMPTE 12M compliant LTC generation, support for all standard broadcast frame rates, file durations up to 3 hours per file, and real time progress tracking. The application manages system resources efficiently when generating large batch series. A macOS menu "Audio Output" picker shows and selects the actual interface and format; format selection is disabled during live playback to prevent conflicts. Enhanced file export reliability and compatibility improvements ensure robust operation with the latest macOS versions, including improved validation, retry logic for transient errors, and enhanced error handling.
Retro LTC Pro is used by film crews, broadcast engineers, and audio professionals for reliable timecode generation in production environments, equipment testing, and post production workflows. The ability to generate up to 99 files in a single batch operation makes it ideal for complex multi camera productions and extended recording sessions.
One-time purchase with no in-app purchases or subscription fees. Once you buy it, you own it completely with all features included.

Version 2.3
- **Cue List Feature**: Build and manage multiple timecode ranges in Custom Live LTC. Add cues with custom names, reorder by drag-and-drop, delete or clear all, and export individual cues with cue names prefixed in filenames. Cached playback prevents glitches, auto-advance includes a 1-second gap between cues to eliminate audio thumps, and background rendering shows a spinner while cues are being prepared.
- **Enhanced File Export Reliability**: Improved compatibility with latest macOS versions including enhanced file validation, retry logic for transient file system errors, improved directory validation for batch operations, and better error handling with user feedback. These improvements ensure reliable file export operations across all macOS versions.
- **UI Improvements**: Clock added to the top header for quick time reference. CRT bezel can be disabled for diagnostics when needed.
Version 2.0
Batch generation allows creating up to 99 LTC files in a single operation, making it ideal for complex multi camera productions and extended recording sessions. Configure start timecode, file length, and offset between files to generate complete timecode series automatically.
Automatic compression creates zip archives of batch files for efficient transfer and storage management. Individual WAV files are automatically removed after compression to conserve disk space.
Enhanced performance optimizations take full advantage of Apple Silicon processors for faster generation times when creating large batch series or extended duration files.
Improved file management includes smart naming conventions that include all parameters for organization and workflow integration. Progress tracking provides real time feedback during batch generation operations.
Resource management features monitor system capabilities and provide appropriate feedback when generating large batch series or extended duration files.
