FAQ

Frequently Asked Questions

Will this make my USB or phone mic sound like a Shure SM7B?

While it cannot change the physical capsule of your microphone, it applies the exact same acoustic processing chain (low-end cleanup, vocal presence boost, gentle compression, and de-reverberation) that top audio engineers use on broadcast microphones.

Does it support remote interview recordings (Zoom, Riverside, Zencastr)?

Yes! Remote interviews often suffer from uneven volume, internet compression artifacts, and inconsistent room acoustics. Our leveler balances speaker levels while stripping background hum.

Are long podcast episodes (1 to 2 hours) supported?

Yes. Because all processing happens client-side using WebAssembly and Web Audio hardware acceleration, long files process directly without server timeouts or file size limits.

Does my episode audio leave my computer?

Never. All decoding, neural cleaning, and WAV export happens entirely inside your browser. No audio is ever uploaded to any server.
