Separate Speakers (MossFormer2)

Speech separation that splits overlapping voices in an AudioFrame into a [AudioFrame] list with one 16 kHz mono frame per separated speaker. Use it ahead of transcription or capture so each voice is processed on its own clean stream.

Denoise Audio (ClearerVoice Studio)

ClearVoice speech enhancement. Accepts AudioFrame (flattened to mono), resamples to model_name native rate (16 or 48 kHz), and emits a denoised AudioFrame. Use upstream of ASR, VAD, or diarisation when quality matters more than latency.

Denoise Audio (FRCRN)

FRCRN speech denoiser (ClearerVoice-Studio): mixes each in_0 AudioFrame to mono, resamples to 16 kHz, and emits a denoised 16 kHz mono AudioFrame on out_0. Use ahead of narrowband ASR or VAD.

Upscale Audio (MossFormer2)

MossFormer2 speech super-resolution. Mixes each AudioFrame to mono, resamples up into a 48 kHz container, and runs MossFormer2_SR_48K to restore the high band lost to low-rate capture, emitting one mono 48 kHz AudioFrame per input.

Denoise Audio (MossFormer2)

Full-band MossFormer2 speech denoiser. Mixes each AudioFrame to mono, resamples to 48 kHz, denoises with the MossFormer2_SE_48K checkpoint, and emits one mono 48 kHz AudioFrame per input. Pick for offline batch cleanup where enhancement quality outweighs latency.
