TinyTone is a full-featured synthesizer sound source for iPhone sound design, stage performance, and recording. Using the on-screen controllers and a MIDI keyboard, you can design and monitor professional synth patches in real time. In addition to standalone app use, ToneEditor can also be loaded as an AUv3 Audio Unit into DAWs such as GarageBand and used as a sound source. It also works as a sound editor for its sister app, TinyTone, allowing you to reproduce consistent sounds with the same sound engine. <Features> ・Powerful Synthesizer Engine Equipped with dual oscillators, envelopes, filters, modulation, delay, limiter, and more. Enables complex sound design. Dual Oscillators with FM Synthesis, switch between Mix and Chain modes for rich tonal possibilities. ・Real-Time Audition Play single notes, chords, and transposition using touch pads. Hear sound changes instantly as you adjust sliders. External input via MIDI keyboard is also supported. ・Preset Management Unlimited user patch storage. ・JSON Export / Import Export patches as JSON. Share via Files app or clipboard. ・AUv3 Support Can be embedded as an AU instrument in DAWs like GarageBand. Reproduces consistent sounds with the same synthesis engine. <How to Use> 【Standalone】 1. Select a preset or start creating from a new patch. 2. Play sounds using the test pad at the bottom of the screen; adjust parameters with sliders to confirm real-time sound changes. 3. Save your created patch to a user slot. 【Using with DAWs (GarageBand, etc.)】 1. Add TinyTone (AU) to a track. 2. Select a factory preset or saved patch from the AU preset selection screen. 3. Play the DAW keyboard to output sound. <Important> ・When using simultaneously with camera or audio apps, noise may occur depending on your environment. Please be careful with output volume. ・Listening to loud audio for extended periods can affect your hearing. When using headphones or speakers, always check your surroundings and volume level. ・Some DAWs (e.g. Ableton Live 11) may not detect iOS-app AUv3 plug-ins. Logic Pro, MainStage, and GarageBand are recommended. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://flicker-jp.com/privacy
Audio Spectrum Pro
Read full descriptionHide full description
A professional audio toolkit for live sound engineers. Audio Spectrum Pro is a complete measurement suite on your iPhone: spectrum analyzer, chromatic tuner, oscilloscope, loudness meter, test-signal generator, and RT60 reverberation time measurement. Everything in one app, with a dark interface built for the stage and the concert hall. SPECTRUM ANALYZER Real-time spectrum from 50 Hz to 16 kHz on a logarithmic scale. Automatic peak detection highlights problem frequencies instantly. The "EQ Suggestions" panel tells you which band to cut and by how many decibels - before feedback ever happens. CHROMATIC TUNER High-precision pitch detection accurate to hundredths of a cent. Supports guitar, bass, violin, viola, cello, ukulele, mandolin, banjo, and a chromatic mode. Adjustable A4 reference, capo support, and a noise gate to reject bleed from the PA. OSCILLOSCOPE Real-time waveform display for signal-integrity checks, phase inspection, and clipping detection. The first thing you reach for when something sounds wrong. LOUDNESS METER Simultaneous RMS and true-peak readout with a scrolling history graph (120 frames). Watch your average level and catch peak spikes before they slam your limiters. TEST-SIGNAL GENERATOR Pink noise, white noise, a logarithmic sine sweep (20 Hz to 20 kHz), or a fixed tone from 50 Hz to 8 kHz - all played through the speaker while the mic keeps analyzing. Tune PA systems, ring out monitor wedges, and find room resonances without a separate signal generator. RT60 REVERBERATION ANALYSIS Tap Start, make an impulse (a clap, a click, or a sine sweep) - the app records the decay, computes T20, and extrapolates RT60. Size up a room's acoustics in seconds and know whether they're working for you or against you. BUILT FOR THE FIELD - Mic gain control with the volume buttons - one hand, while the other stays on the console - Fully dark interface - readable under stage lighting, easy on your night vision - Landscape orientation - lay it on the meter bridge or a side table - Three interface languages: English, Russian, Ukrainian Microphone access is required. A speaker or headphones are needed to play test signals.
