    Frequency Detect Software. ToneDet - Tone Detector v.1.0. ToneDet is used to monitor an audio signal a for specific frequency tone or multiple tones. Although it can detect any audio frequency, ToneDet is usually used to detect very low frequency tones that cannot be heard by humans. Typical Applications include Radio Network Broadcasts (to automatically trigger commercial …

Audio Frequency Detector - Arduino Project Hub

    https://create.arduino.cc/projecthub/lbf20012001/audio-frequency-detector-617856
    This Arduino project displays the approximate frequency of the loudest sound detected by a sound detection module. For this project, the analog output from the sound module detector sends the analog audio signal detected to A0 of the Arduino Uno. The analog signal is sampled and quantized (digitized). A Fast Fourier Transform (FFT) is then performed on the …

7 Best Free Audio Spectrum Analyzer Software For …

    Frequency Analyzer is another free audio spectrum analyzer software for Windows. It is a simple and easy to use software with minimal options available at its interface. Like other software, it also generates frequency spectrum in real time. For that purpose, you need to either connect a microphone or provide input as WAV or Bitmap file.

software - App for audio feedback frequency detection ...

    https://sound.stackexchange.com/questions/25118/app-for-audio-feedback-frequency-detection
    So feedback detection is often a matter of working out the harmonics rather than a specific frequency. This is to say that after a short while, the dominant feedback frequencies may be 1K and 2.5K, but the engineer may actually pull down 500Hz based on noticing this low frequency just when the feedback started.
