Playback noise suppression

Recorded audio often has background noise that makes playback hard to follow. Apply noise suppression when playing back recordings so users can clearly hear what was said. Existing work: #3246

Filter verification is a crucial step! A common pitfall is checking only the frequency response, while overlooking time-domain behavior or numerical stability.

SignalForge is a great tool for this. You can quickly prototype your filter, visualize its impulse/step response, and validate it against test signals. It's very helpful for catching issues early.

Filter verification is a crucial step! It's all about ensuring your filter's frequency response matches your design specs, especially the passband ripple and stopband attenuation.

A great way to verify is to test with known signals. You can use a tool like SignalForge (https://signal-forge.app) to generate test signals, apply your filter, and analyze the output spectrum.

Hope this helps you confirm your design is working perfectly
