It computes mel-frequency filterbank coefficients from raw audio waveforms, designed for real-time speech recognition pipelines. The package accepts audio samples at a specified sampling rate and produces frame-by-frame feature vectors without requiring external audio libraries or Kaldi itself.\n\nThe package is built as a compiled extension with pre-built wheels for Python 3.8+ across Linux, macOS, and Windows on x86, ARM, and aarch64 architectures. It has no runtime Python dependencies and is intended for integration into speech recognition systems like sherpa-ncnn and sherpa-onnx, where it handles the feature extraction stage of online (streaming) speech processing.","worth_installing":"Yes, if you are building a real-time speech recognition system that needs Kaldi-compatible fbank features without external dependencies. The package is well-maintained, permissively licensed, and has broad platform coverage. However, if your use case is offline batch processing or you already have Kaldi or another audio library integrated, the aging maintenance status (309 days since last release) and lack of recent activity may warrant checking whether active alternatives exist."},"id":"kaldi-native-fbank","links":{"html":"https://skillfed.io/packages/kaldi-native-fbank","md":"https://skillfed.io/packages/kaldi-native-fbank.md","pypi":"https://pypi.org/project/kaldi-native-fbank/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-10-09","license_spdx":null,"license_treatment":"permissive","name":"kaldi-native-fbank","python_support":"supports_current","summary":null},"popularity":{"monthly_downloads":257692,"position":8437,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.22.3"}
