Audio Function Generator PRO is a Frequency (ies) a,d Noise generator including 6 distinct modules. The first: Frequency Generator. Enter a frequency in the text field (range 1.0 – 21kHz). Select one of the four waveforms: sine, rectangular, triangular or sawtooth or choose a musical note's frequency. Press the play button to start or stop playback. The frequency slider provides another alternative to the text field entry via the keyboard as well as the Fine Tune row. Just below this row, another one allows you to save your settings as a preset. (The preset setting opens a popover which allows you to customise your presets.). You can also save them in the dedicated menu. Set the volume via the volume slider or via the vol+/vol- buttons on your iPhone or iPad. Tapping on the Master Volume button opens a popover so you can enter the volume directly (not just via the volume slider). The selectable range is either 0-100 or -60dB to 0dB if you prefer using dB entry. The maximum volume is determined by the respective value configured on the Settings page. A Beats-per-minute setting allows you to pulse the audio at a custom on/off timing. The Beats-per-minute menu allows you to generate a pulsed audio signal. You can pulse the generated audio within a range of 1 – 600 BPM. The waveform with currently selected frequency and amplitude is shown right above the Master Volume button. You can Pan the signal to the L or R output of your iDevice and and change the phase of the generated audio for the left and right channel individually. The second: Sweep Frequency or volume In sweep mode, the function generator runs in both directions, min => max frequency and max => min frequency within the specified time. In Volume Sweep mode, the amplitude is increased from 0-100% within the specified time. If the Repeat button is selected, the sweep will repeat in a loop. If you enable the Siren Mode (Setting menu), the sweep function increments from min to max and then decrements to min again. Then it repeats from min to max and so on. Select a start frequency by entering a value in the text field or set the frequency via the frequency slider. Then tap on “Set Start”. This sets the sweep start frequency. Do the same for a stop frequency. The sweep time can be set via the sweep time slider. Its max value can be configured in the Settings menu. The current sweep time is indicated by the sweep timer. Third: Noise There are 6 types of noise that can be played: White Noise, Pink Noise, Violet Noise, Grey Noise, Brown Noise and Blue Noise. Fourth: Dual Frequency Generator The dual frequency generator provides means for outputting a different frequency per each channel – left or right individually. You can even output different waveforms per channel. Say you want to play 440Hz sine on the left channel, and 1000Hz saw-tooth on the right channel Also the volume and phase of each channel can be controlled individually. Fifth: Multitone Generator (available as an Audiobus App) The MultiTone Generator provides means to create and play up to 8 completely individual tone combinations in parallel from the 4 describe above. The frequency and the volume of each tab can be set individually. The last module is a Click Tracks generator Set the pause between the Click tracks and it's Amplitube. To conclude: This App is awesome. Can be use by Sound Engineers, Technicians and even Musicians. Despite the technical side of this App, it is fun. 4 of these modules can be used as Drone. The latest Click Tracks like a metronome. But the fifth: The Multitone Generator is a Drone in its own right! For this reason the developer had the judicious idea to make it a full-fledged Audiobus compatible App!I will post his review very soon! I love this App. Very well thought out, very well done... Nothing to say. A Killer App! A Must Have!!!!! Price $2.99 Author Thomas Gruner Tool | Noise & Frequency Generator, Drone version 3.5.0 The App Store descriptionThis is the highly recommended and praised Function Generator App - an amazingly great and powerful tone generator. Enriched with a vast amount of features yet it is extremely intuitive and designed for simplicity.
Get to know this great App now! It is very well maintained and has received considerable upgrades over the past years. So, … what can you do with this App? • PLAY TEST TONES Sine, Rectangular, Triangular and Sawtooth. • PLAY FREQUENCY SWEEP TEST TONES in both directions (minimum to maximum frequency and maximum to minimum frequency). • PLAY VOLUME SWEEPS (from minimum to maximum volume). • Try the SWEEP REPEAT / WOBBLE function. • Try the MUSIC TONES PLAYBACK. • Experiment with the huge FINE TUNE SELECTON, PRESETS SELECTION! • Or create your own CUSTOM PRESETS! • And SAVE an endless amount of CONFIGURATIONS (Frequency, Sweep, Noise) for later quick access and direct playback function. • Even play back different kinds of NOISE – White, Pink, Violet, Grey, Brown, Blue is also supported. The Function Generator is AMAZINGLY INTUITIVE and SIMPLE! AND THESE ARE THE ADVANCED SETTINGS/FEATURES: => Extending The Frequency Range => Extending The Sweep Times => Changing Min/Max Slider Frequency Ranges => Changing Max Sweep Time Slider Range => Changing Signal Amplitude => Enabling Of The Sweep Repeat / Wobble Function => Frequency Slider Setting to Linear or Logarithmic => Left/Right Channel Individual Selection => Permanently Saving Custom Presets => Saving Of Endless Number Of Audio Configurations => Phase Out Setting (custom phase shift of the generated signal) => BPM (Beats per Minute) Feature => Dual Function Generator => MultiTone Generator (playback of up to eight individual tones) => Click Track Generator => Background Theme Selection (Light/Dark) Check out the new Tutorial page: www.ee-toolkit.com/audio-function-generator
