Audio / Spectrum Analyzer vs Fine Tuner

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 - Spectrum average - 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 the audio signal (Sine, Triangle, Squire, Saw) - Generates the noise signal (white noise, pink noise) - 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. Spectrum Average 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. Generates the audio signal : Set the audio signal to be generated. - There are 4 types of waveform. (Sine, Triangle, Squire, Saw) - It can set the value of the frequency in 20Hz - 20000Hz. 10. Generates the noise signal : Set the noise signal to be generated. - There are 2 types of noise. (White noise, pink noise) [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).

Fine Tuner – A precise chromatic tuner for your string instruments Key Features Fine Tuner is a chromatic tuner designed first and foremost for string instruments: guitar (classical, electric, acoustic), bass (4 and 5 strings), violin, viola, cello, double bass, ukulele, mandolin, banjo and harp. Its chromatic detection also tunes many other instruments, including wind instruments. It offers both standard and alternative tunings (drop D, drop C, open tunings…), especially for guitars and basses. A chromatic mode allows automatic detection of all played notes. New: discover the Circle of Notes — an interactive tool that lets you tune your string instrument by ear! Listen to notes from octaves 1 to 7 with different instrument sounds, or explore major, minor, and many other chords. Made for string instruments Whether you play violin, viola, cello or double bass, Fine Tuner shows the note and the deviation in cents for accurate tuning, both arco and pizzicato. Guitarists, bassists, ukulele, mandolin, banjo and harp players: tune every string quickly, even in a noisy environment. Operating Modes • Automatic mode: Detects notes automatically within the selected tuning range. • Manual mode: Allows manual selection of the note to tune using the note selector. • Circle of Notes: Play and listen to notes and chords to tune by ear. Display Modes • Precision view: Default precision range of ±50 cents, with a needle indicating the position relative to the target frequency. • Graphical view: Default precision range of ±500 cents, with a graph to track tuning adjustments. • Expanded view: Displays a wider range up to ±1000 cents, ideal for visualizing large deviations. • Spectrum: Analytical view displaying the frequency spectrum in real time, allowing detailed observation of harmonics and sound distribution. Customization Options • Reference frequency: Adjustable between 400 Hz and 480 Hz, with a default value of 440 Hz. • Temperament selection: Choose between Equal Temperament, Pythagorean, or Meantone according to your musical style and instrument. • Deviation tolerance: Adjustable to set the desired tuning precision. • Note display type: Choose between standard or Latin notation. • Gain adjustment: Microphone sensitivity calibration for optimal note detection. • Accidental display: Option to show sharps (#) or flats (b). Custom Tunings • Create custom tunings with your own note frequencies. • Manually define each note for advanced tuning control. • Support up to 99 notes per tuning. Note Display The main detected note is displayed centrally, along with adjacent semitones for better reference. Shows the target and current frequency, as well as the difference in cents for precise tuning. An Ergonomic Tuner Fine Tuner adapts to your preferences, whether you use portrait or landscape mode. A Free and Accessible Tuner Fine Tuner is available for free with non-intrusive ads to support development. You can also remove ads through an in-app purchase for a completely clean experience.
