# 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) |
