Frequently Asked Questions (FAQs)
Q: How does the bass booster prevent distortion and crackling?
A: Our tool incorporates a dynamic range compressor and soft-limiter node. When heavy bass creates high amplitude spikes, the limiter smooths the peaks to avoid digital clipping and crackle.
Q: What is the best frequency setting for deep 808 bass?
A: For deep 808 rumbles, choose 60 Hz or 100 Hz with +8dB to +12dB gain. For punchy rock and pop drums, 150 Hz to 200 Hz gives great punch and body.
Q: Are my songs uploaded to an external server?
A: No! All audio decoding, equalizing, and encoding occur 100% locally on your computer or phone. Zero audio data is transferred over the internet.
