--- license: mit tags: - coreml - audio - speech-enhancement --- # Clarity transient network (Core ML, FP16) Finds clicks, knocks and other short noises in speech for Clarity Sound Studio, a free, open-source macOS app. It runs after noise reduction and gives a keep mask per STFT bin and an event probability per frame. | | | | --- | --- | | Files | `TransientNet-v1-fp16.mlmodelc` (mask and events) and `TransientNet-v1-fp16-event.mlmodelc` (the same checkpoint, event output only); compiled ML Programs, FP16, macOS 14+ | | Model | 1.1 M parameters over log power spectrum frames | | Training | Speech from the CSTR VCTK Corpus mixed with sound events and backgrounds from FSD50K (speakers p232 and p257 held out) | ## Licence The model is released under the MIT licence; see `LICENSE`.
