This Skill helps improve the quality of audio input for transcription by allowing users to tune various audio pre-processing filters, such as highpass and lowpass filters, de-emphasis, and automatic gain control (AGC).
Use the wavecap-filters skill to adjust the highpass cutoff frequency to 350 Hz and the lowpass cutoff frequency to 3500 Hz.

To improve audio transcription clarity, adjust highpass and lowpass cutoff frequencies to remove rumble and hiss, and enable automatic gain control to normalize speech levels in noisy environments.
Automatic gain control normalizes incoming audio levels to ensure speech is consistently audible without clipping, preventing transcriptions from missing words caused by quiet audio inputs.
Configure audio pre-processing filters by updating cutoff frequencies, de-emphasis time constants, and AGC target RMS values in the state/config.yaml file, then restart the transcription service.
Use de-emphasis adjustment when processing weak radio signals or processed web streams to compensate for pre-emphasis applied during transmission and normalize treble frequencies for clearer speech transcription.
Audio transcription misses words during quiet speech because input levels are too low; configuring automatic gain control with an appropriate target RMS normalizes audio volume to resolve this issue.
Yes, audio filter tuning supports various input sources by allowing you to adjust highpass and lowpass cutoffs alongside AGC settings to optimize transcription quality for clean studio feeds, weak radio signals, or noisy environments.
