"Audio Frequency Analyzer" is a powerful real-time audio analyzer (RTA) app for iPhone. With its simple operation, you can easily measure and evaluate your sound environment. This app measures the frequency response in 30 split band scale of 1/3 octave in real time. It can also display the FFT analysis results. It supports calibration for 1/3-octave bands. By adjusting the characteristics to match not only the built-in microphone but also your external microphone, it achieves high measurement accuracy. "Audio Frequency Analyzer" can be used for various applications, including sound room tuning, speaker settings, audio equipment testing, stage setup measurement, sound mixing environment evaluation and noise environment investigation. Features: - Frequency spectrum response measurement of 1/3 octave unit, 30 bands. (OCT) - FFT Analyzer (FFT) - Observation frequency range: 20 - 23000 Hz - Logarithmic amplitude display. - Touch-scroll function to adjust visible amplitude ranges. - Display the measured value of 1/3 oct bands at OCT mode. (dB@OCT) - Function to change the graph slope at FFT mode. (Slope): -3dB/oct (less than 1kHz), +3dB/oct (1kHz or higher) - Peak hold function. (Hold) - Average display function. (Avg): Time linear averaging. Fast-2.56sec, Slow-12.8 sec - Display response control. (Fast/Slow) - Reset of Measurement display position. (Scroll) - Snapshot of Measurement display. (Snap) - Calibration function in OCT mode. (Calibrate): 1/3 octave band offset and total offset setting. - Supports built-in microphone, headset microphone, and external digital audio connection. Note: The first time you access your microphone and photos after installing the app, the iOS system will ask you for permission to access them. If you have not enabled this setting, the app will not be able to access them due to iOS system privacy restrictions. Please enable the access permission in the iOS setting "Settings > Privacy & Security > Photos or Microphone". Please visit our iOS app support page for more information about this app.

Are you producing? Want to sound test your speakers or tune your instruments? Or simply, do you want to generate sounds and listen to the generated sounds in different frequencies? Well, then you need a frequency sound generator to produce sound waves in different frequencies. Introducing Frequency Sound Generator! Frequency: Generator Sound player lets you generate a sine, square, sawtooth or triangle sound wave with a frequency between 1Hz and 22000Hz (Hertz). It produces accurate tone & soundwaves while being simple and easy to use. Additionally, pick from a wide variety of notes by taping the notes icon. No matter if you need to sound test and generate high frequency sounds or low frequency sounds, our frequency tone generator is your #1 best solution. EASY CONTROL Frequency: Sound Generator allows you to easily change the soundwaves from the main menu. Simply tap on the sound wave icon and pick between sine, square, sawtooth or triangle. ANIMATED SOUND WAVE You’ll love the animated sound wave function which visually represents the sound for a given frequency. You can change waveform by clicking on a round button at the left side and get a different sound and animated wave. ADJUST FREQUENCY & VOLUME Adjust the sound generating frequency easily by dragging the yellow dot. Make use of the - & + buttons for added adjusting precision. Additionally, control the volume of the generated sounds from 0-100%. NUMEROUS USES: This sound generating app can be used in multiple use cases: - Test your hearing. A human being is capable of hearing frequencies in the average range of 20Hz-20000Hz. This range is getting smaller by age, so it’s interesting to sound test your hearing capabilities. - Test speakers and headphones for the high end (treble) and low end (bass) tones. - Use this app as an instrument tuner when playing or producing. - Cleaning water from the speaker. Since sound is making small vibrations it can help to shake off unwanted water from your speakers. - Find your tinnitus frequency. NOTE: Since mobile phones are not high-quality audio sources and in-built speakers may vary in quality, sometimes users can hear sounds at very low or high frequencies even beyond the scope of human hearing. That noise is not sound of a given frequency but static or “parasite” noise generated by your mobile device. For the best experience use a pair of good quality headphones.

Verdict

The call

The clearest difference is price: Frequency at Free against Audio Frequency Analyzer's $9.99. Frequency also leads on rating (4.7 vs 3.7) and update cadence (fortnightly vs every 8 months). Audio Frequency Analyzer's advantage is ads (none vs shown). On in-app purchases and device support there is nothing between them.
