Generator vs auGEN X

A high-quality audio Signal Generator for the iPhone. Now you can have a professional grade signal generator for your iPhone. Create sine waves, square waves, white noise, and pink noise. Don't let the well-worn look of this classic audio must-have fool you, Generator is accurate, reliable, precise, and clean. ** NEW! Now supports remote control over WiFi from our AudioTools app. Connect an iOS device running Generator to your audio system, link to AudioTools on another device, and control Generator from AudioTools as you are free to move around. Requires that both devices be on the same LAN. In sine and square wave mode, you can select between 20Hz and 20kHz using a controller that has three resolutions: octave, 1/3 octave, and fine. Frequency selection is controlled by smooth-gliding interlocking control wheels. Just spin to change frequency, by octaves, 1/3 octaves, or select fine mode to sweep through any value. *** NEW: Tap the frequency screen to pop up a keyboard so that you can enter any exact frequency. *** NEW: Tap the Wobble button to create a warble-tone signal for acoustics work. Doubles as an emergency siren! When you are generating pink noise and white noise, you can select full band (20Hz-20kHz), or octave band limited noise for acoustical testing. All waveforms are laboratory accurate, and use ANSI / IEC spec filters where appropriate. The frequency sweeps smoothly, with no glitches. The mute is soft, to prevent loud impulses when mute or turning on a lower-frequency signal. This signal can be sent to both channels (stereo), just the right or left channel, or the right channel output phase can be inverted for pseudo-balanced mode. This mode can be used with our iPhone Balanced Cable Adapter to get a balanced signal from your iPhone. See our web site for more information. On an iPhone 3G, we have measured distortion at .006% THD at 1000Hz at full volume (+6.5dBu balanced). See our web site for more level details. Note that digital square waves suffer from aliasing problems, and sound very strange above about 1500Hz. Future versions will have options to select different skins.

auGEN X bridges the creative musical world of artists with the exacting scientific world of audio engineers. What started as a precision audio test utility has grown into a fun experimental sound design instrument. On one end use auGEN X to help set up, test, calibrate, and optimize your audio system. On the other use it to create a wide variety of interesting sounds. auGEN X has a full-featured audio oscillator, a high quality noise generator, and an impulse generator. The simple yet powerful user interface is designed for fast, precise, intuitive control over your signals. auGEN X works both as a Stand-Alone App and as an AUv3 Audio Unit Extension responding to MIDI In and BPM Sync from Hosts. I started making this app because as an audio electronics engineer I could not find a single audio generator that does everything that I require AND is an AUv3 Audio Unit. auGEN X has expanded into a musical tool for exploring and learning sound design. Our goal is for auGEN X to be an Essential in your audio toolbox. We hope you enjoy it and we’re excited to hear the cool things that you do with auGEN X!
