It's an incredible tool for all audio engineers and musicians ... My mixing has improved by leaps and bounds after just a few weeks with Quiztones.” — Austin M. “I love this app. Has taken my ability to hear frequencies to heights I never imagined was possible at this point in my career. This app is a game changer. Be consistent with it and it will change the way you hear music.” — JayAllDay “This is fantastic. I’m a bit of a workaholic, and blind, audio engineer. This is like the holy grail of an iOS game for me. It’s simultaneously fun and productive. I can play on the go to have better ideas of what I’m hearing on my phone for later correction in Pro Tools, or plug into one of my monitor sets at home to test my instinct... and it’s a game, with categories and scores. Much respect.” — justmikeaf “Trained me up well! This app helped me become MUCH faster with EQ, and helped me know with greater precision what I'm hearing all around .” — MarkBvllock ===== Quiztones Terms: https://theproaudiofiles.com/quiztones/terms/ Apple Standard EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

This RTA app supports simultaneous display of "Audio Waveform", as well as the FFT-based "Amplitude Spectrum" (frequency magnitude) and "Spectrogram" (frequency distribution over time), for audio signals input from a microphone. (FFT: Fast Fourier Transform, RTA: Real Time Analyzer) [Features] - Supports simultaneous display of Waveform / Spectrum / Spectrogram - Supports orientation both portrait and landscape - FFT size - Window function - Time Averaging (FFT Frames) - Spectrum Tilt - Frequency weighting (Flat, dBA, dBC) - The type of expressing the frequency of Spectrum / Spectrogram (Linear, Log) - Displays the peak level and its frequency of the spectrum - Peak Hold (displays the results of holding past peak values ​​of the spectrum) - Octave Analysis (displays the spectrum divided into octave bands) - Generates Basic Waveforms (Sine, Triangle, Squire, Saw) - Generates Measurement Signals (Noise, Sweep, TSP) - Pitch meter display The Pro version offers Ad-Free Viewing and High-Resolution Analysis (FFT size: 16384, 32768, Spectrum Average: 4, 8). [Setting items] 1. Screen structure : Select the display screen configuration. View Num : 1, 2 View Type : - 1 screen : Wave (Waveform) / 1D (Spectrum) / 2D (Spectrogram) - 2 screens : W+1D / W+2D / 1D+2D Layout : Vertical / Horizon 2. Frequency Axis Scale Type : Selectable the type of expressing the X direction (frequency) of Spectrum / Spectrogram. - Linear: Distributed at equal intervals - Log: The intervals increase logarithmically 3-1. FFT size : 1024, 2048, 4096, 8192, 16384, 32768 (* 16384, 32768 is available in the Pro version.) 3-2. Window function : Hanning, Hamming, Blackman, No window 4. Time Averaging (FFT Frames) : Number of spectrum average for a display of spectrum. 1, 2, 4, 8 (init value: 1) (* 4 and 8 are available in the Pro version.) Higher value will make the spectrum less noisy and more smooth, at the cost of lower time resolution. 5. Spectrum Tilt : Compensates the visual slope of the spectrum around a 1 kHz pivot. -6.0 to +6.0 dB/oct in 0.5 dB/oct steps (0 means no tilt). 6. Frequency Weighting : Selectable frequency weighting. - Flat: No frequency weighting is applied. - dB(A): Frequency response that takes into account human hearing. - dB(C): Relatively flat response. 7. Peak Hold : Displays the results of holding the past maximum values ​​(peak values) of the spectrum. 8. Octave Analysis : Displays the results of classifying the spectrum into octave bands. Division method: - FFT: Spectral display - 1/24, 1/12, 1/6, 1/3, 1 octave: Display divided into octave bands Calc method: - Max: Displays the maximum spectrum value in each band - Average: Displays the average spectrum value in each band 9. Basic Waveforms : - There are 4 types of waveform. (Sine, Triangle, Squire, Saw) - It can set the value of the frequency in 20Hz - 20000Hz. 10. Measurement Signals : - There are multiple types of noise. (White noise, Pink noise, MLS, Sweep, TSP) [Other] - Background color: Black, White - WaveForm: Line Color (Green, Yellow, Invert), Line Width (1.0 ~ 6.0 px) - Spectrum: Bar color (Green, Yellow, Color patterns) - Spectrogram: Colormap, Display range (-150 ~ -60 dB), Display time (4 ~ 60 sec), Apply Spectrum Tilt - Bluetooth connection policy selection (disabled, HFP, A2DP). - Scaling of Waveform / Spectrum display in the Y direction (magnification: 0.5 - 2.0). - Scaling of Spectrum / Spectrogram display in the X direction (magnification: 1.0 - 16.0).
