Audio Codec Algorithms
Decoding and encoding for few basic audio codecs implemented in Rust:
Features:
- supports no_std
- no heap memory allocations
- no unsafe code
- no panicking
- only dependencies for testing: no-panic and criterion
Running the example
Try out decoding and encoding values:
cargo run --example codec-tester decode ulaw 3 130 221
cargo run --example codec-tester encode alaw 10 -5430 3263
cargo run --example codec-tester encode adpcm_ima 25 40 60 80 100 160 220
cargo run --example codec-tester decode adpcm_ima 7 7 2 2 2 7 5
Running tests
Run:
# run the tests
cargo test
# ensure good code quality
cargo clippy
# ensure that the release build never panics
cargo test --release --features internal-no-panic
Performance testing:
cargo bench
There is a GitHub Action called "Cross-platform tests" (cross-test.yml), which automatically
runs cargo test for little-endian 64-bit x64_86 and big-endian 32-bit PowerPC.
