Feature Showcase
App Feature Details
From waveform selection to fine-tuning frequency, every interface in FreqForge is designed with precision and efficiency in mind.
FreqForge generates exact frequencies from 20 Hz to 20 kHz across four waveforms — built for musicians, audio engineers, and anyone who needs a tone they can trust.
From a quick reference pitch to a full acoustic sweep, FreqForge covers the range professionals expect.
Sine, square, triangle, and sawtooth — each rendered with clean, alias-free synthesis.
20 Hz to 20,000 Hz with a logarithmic slider that feels natural to the ear.
Glide between any two frequencies, linear or logarithmic, over 1–60 seconds.
Run two independent channels at once — ideal for binaural and intermodulation testing.
Real-time waveform rendering gives instant visual feedback as you play.
Ten built-in frequencies — A4, 1 kHz, 528 Hz and more — plus unlimited custom saves.
From sub-bass rumble to the edge of human hearing — dial in any frequency to two decimal places.
FreqForge runs entirely offline. No accounts, no analytics, no third-party SDKs.
Custom presets are saved on your device alone, never uploaded anywhere.
Every feature, including sweep and dual tone, works fully offline.
Zero advertising or analytics libraries are bundled with the app.
