## プロジェクトの歴史と使われ方

ltc-tools is a small collection of command-line programs for generating, dumping, converting, and triggering against linear timecode.

### プロジェクトの歴史

The official README is deliberately short: it identifies the project as command-line tools for linear timecode and notes that it requires x42/libltc. The repository contents show C sources and roff man pages for tools such as `ltcgen`, `ltcdump`, `jltcgen`, `jltcdump`, `jltc2mtc`, `jltcntp`, and `jltctrigger`.

### 採用の歴史

Adoption evidence is niche but real: the supplied package-manager facts list Homebrew, MacPorts, and Nix packages, and GitHub shows about 91 stars, 23 forks, 200 commits, and a v0.7.0 release. This is consistent with a specialist audio/video utility rather than a general-purpose media application.

### 使われ方

Users install the package to get focused CLI tools for LTC workflows. The executable names map directly to package-nerd use cases: generate LTC, dump or inspect LTC, bridge JACK-oriented LTC to MIDI timecode, and perform trigger or NTP-related timecode tasks.

### パッケージ好きにとっての重要性

ltc-tools matters in package histories because it exposes pro-audio synchronization primitives as simple Unix commands. It is the sort of package that rarely appears in broad developer tooling discussions but is important in audio, broadcast, and measurement setups where linear timecode must be inspected or synthesized without a large DAW.

### タイムライン

- 2019: GitHub lists v0.7.0 as the latest release, with statically linked `ltcdump` binaries included.
- 2020s: Homebrew, MacPorts, and Nix package the toolset for command-line LTC workflows.

### Related projects

- x42/libltc is the required LTC library named by the README.
- MIDI timecode is related through the `jltc2mtc` executable.
- JACK-oriented tooling is implied by the `jltc*` executable family.
