The official CLI tool to manage your Amplitude projects, local resources, and licenses.

• Rust (Edition 2024, requires Rust 1.85+) - Install via rustup
• Amplitude Audio SDK - Required at build time for FlatBuffer schema code generation
  • Clone from: https://github.com/AmplitudeAudio/sdk
  • Set the AM_SDK_PATH environment variable to point to the SDK root directory

# Clone the repository and the Amplitude SDK
git clone https://github.com/AmplitudeAudio/cli.git
git clone https://github.com/AmplitudeAudio/sdk.git

# Set AM_SDK_PATH to the absolute path of the cloned SDK
export AM_SDK_PATH="$(pwd)/sdk"

# Build and test
cd cli
cargo build
cargo test

# Clone the repository and the Amplitude SDK
git clone https://github.com/AmplitudeAudio/cli.git
git clone https://github.com/AmplitudeAudio/sdk.git

# Set AM_SDK_PATH to the absolute path of the cloned SDK
$env:AM_SDK_PATH = (Resolve-Path sdk).Path

# Build and test
cd cli
cargo build
cargo test

cargo fmt              # Format code
cargo clippy           # Run linter
cargo test             # Run all tests
cargo run -- --verbose # Run with debug logging
cargo run -- --help    # Show available commands

Tests use priority tags (P0 = critical, P1 = high, P2 = medium, P3 = low) for selective execution during local development:

cargo test p0          # Critical tests only (fastest)
cargo test p1          # High priority tests

Every SDK asset type can be created, listed, updated and deleted through am asset:

Each type has create, list, update and delete (bus-file has no update); run am asset <type> --help for the flags. Examples:

am asset sound create explosion --file audio/explosion.wav --bus sfx
am asset sound update explosion --gain 0.5
am asset sound delete explosion --force   # --yes is an alias
am asset rtpc create wind --min-value 0 --max-value 10
am asset attenuation create room --max-distance 50 --shape sphere --inner-radius 5 --outer-radius 10 --curve-part 0,1,1,0,Linear
am project validate --rtpc-only

Every update keeps the keys it does not know about, so hand-edited files are safe. References between assets (buses, attenuations, effects, switch groups, event targets, soundbank entries) are strict: they must exist, and delete refuses to remove an asset that is still referenced. Soundbank entries use runtime extensions; effects are compiled to .amfx.

am project validate checks every asset type plus the bus and engine config files. --sounds-only, --collections-only, --effects-only, --switches-only, --switch-containers-only, --events-only, --soundbanks-only, --attenuations-only, --rtpc-only, --pipelines-only, --buses-only and --engine-configs-only narrow the check. The RTPC rules (min_value < max_value, default_value inside the range) are stricter than the SDK, which clamps or yields NaN; they are reported as errors.

Tests change the working directory, so run them single-threaded and point AM_SDK_PATH at the SDK:

AM_SDK_PATH=../sdk cargo test --no-fail-fast -- --test-threads=1

Release notes are generated from commit messages, so the behavioural changes that affect scripts, agents and CI are listed here.

• An asset reference of ID 0 and a reference to an asset that does not exist are now validation errors (ERR_VALIDATION_REFERENCE, ERR_VALIDATION_EMPTY_REFERENCE) in create, update and project validate. Reference flags accept names or numeric IDs.
• --bus is required when creating a sound, a collection or a switch container (no prompt in --json or non-interactive runs; the error names the flag).
• am asset switch-container create requires --switch-group.
• am asset effect create requires --effect-type.
• A hand-written collection with a non-empty sounds list and no sounds_type no longer parses.
• update commands preserve unknown top-level keys of the file instead of dropping them.
• delete refuses an asset that is still referenced (ERR_ASSET_IN_USE, naming the assets, soundbanks or engine configs that use it). --force / --yes do not override it.
• am build writes effects as .amfx (previously .amenv); soundbank effect entries use .amfx.
• Switch state IDs are preserved across edits instead of being renumbered.
• Soundbanks always carry all eight asset lists, and an empty soundbank is valid.
• Files written by the previous CLI that the SDK could never load (bus ID 0, a bus without fader, null fade blocks) now fail update until they are repaired; the error names the fix.
• am project validate now also checks attenuations, RTPCs, pipelines, *.buses.json and *.config.json files, so projects that passed before can report new errors. am asset sound delete is new.
