Precise Hz, White Noise, Multi-tone Gen. Essential tool with WAV & CSV support
ā FNam Frequency,Noise Generator Engineers need tools that are ready to use ā anytime, anywhere. FNam Frequency,Noise Generator is the ultimate signal source tool designed for audio engineers, developers, and general users who demand professional-grade performance from a smartphone alone. From precise audio testing to white noise for focus and concentration, it delivers every signal waveform you need. High-quality 16-bit 44.1kHz PCM synthesis / Core signal generation runs entirely on-device / User-generated audio data is never uploaded externally. ā New Feature 1. Ensemble Control (Multi-Device Sound Control) - Remotely control multiple devices over Wi-Fi. - Control each device individually or run synchronized pattern sequences (Pattern Control). 2. Frequency Response Preview (requires the FNam FFT Spectrogram Analyzer app) - Connect FNam FFT Spectrogram Analyzer and FNam Freq, Noise Generator over Wi-Fi. - Measure frequency response or impulse response using the configured noise signal. - Review FIR modeling results and Bode plots directly in FNam Analyzer. ā Key Features ⢠Single Tone Generator - Generates Sine, Square, Triangle, Sawtooth, and PWM waveforms. - Frequency range: 20Hz to 20,000Hz (Precise Hz control). - Modulation modes: Chirp (Sweep), Log Chirp, and Burst signals. - Harmonics synthesis for rich tone generation. - Noisy mode to test SNR performance. ⢠Multi Tone Generator - Mix up to 50 simultaneous waveforms (Sine, Square, etc.). - Perfect for intermodulation distortion (IMD) testing and complex sound synthesis. - Individual control of Frequency, Amplitude, and Phase per tone. (Premium) ⢠Colored Noise Generator - Generate White, Pink, Brown, Blue, and Violet noise. - Adjustable Low-cut and High-cut filters to shape the noise spectrum. - Real-time FFT spectrum preview. ⢠Noise Maker - Advanced sound design tool with LFO (Low Frequency Oscillator). - Dual Band and Notch filter support with Resonance (Q) control. - Phase Invert function for ANC (Active Noise Cancellation) testing. ⢠Impulse Generator - Generates precise Dirac Delta spikes. - Essential for testing Impulse Response (IR) and room acoustics. ⢠External Data Load - Load and play WAV files. - Import CSV data to convert numerical data into audio waveforms. (Premium) - Playback speed control and Sample Rate adjustment. ⢠Ensemble Control (Multi-device sound control) - Remotely control multiple devices over Wi-Fi for multi-device testing, advanced field evaluation setups, and synchronized audio experiments. - Provides Pattern Control to individually or simultaneously control multiple devices with custom sequences. ⢠Frequency Response Preview(requires the FNam FFT Spectrogram Analyzer app) - Remotely output the configured test noise and record the response on the Analyzer. - Review frequency response, impulse response, FIR modeling results, and Bode plots. ā» Measurement accuracy may vary depending on device performance, latency, speaker, microphone, and room conditions. ā Convenience & Professional Tools - Off Timer: Automatically stops playback after a set duration. - Fade Out: Smoothly decreases volume before stopping. - Background Playback: Keep generating signals even when the screen is off. - Screen Saver Mode: Keep a clean, low-distraction display during long playback sessions. - Preset System: Save and load your frequency settings instantly. ā Use Cases - Audio Equipment Test: Test speakers, headphones, and subwoofers. - Impulse or Frequency Response Test. - Hearing Test: Check your audible frequency range. - Sound Masking: Use Pink/Brown noise for sleep, study, and relaxation. - Engineering: Signal processing analysis and educational demonstrations.
