Oscillator is a simple and rough audio generator application which has the following functions. You can use it as a test tone and play it as a strange musical instrument. - Four waveforms. (i.e. sine wave, square wave, saw wave and white noise.) - Exponential Frequency control using the slider. - Frequency numeric input using the software keyboard. - Equal distance panning control using the slider. - dB style amplitude control using the slider. - Sound output on/off button. - All sliders and buttons are multi-touch controlled. Please note the limitations below before you purchase/use this application. - The frequency control is not effective with the white noise oscillator. - The panning control is not effective with an iPhone internal speaker because it is monophonic. Use headphones or stereo speakers. - The audio output might be interrupted on a keyboard input, a view change and so on. - The accuracy of the audio output is not very high but it is reasonable.

Your Fingertips Create New Sounds OscDrax is an innovative iOS waveform synthesizer that enables professional sound design through intuitive touch controls. Simply draw waveforms with your finger to instantly create original tones. Combine four independent tracks to build complex, rich soundscapes. Unleash Creativity with the Waveform Editor Our waveform drawing system maximizes the potential of touchscreen technology. With 512-point high resolution, accurately reproduce any waveform you imagine. Classic waveforms like sine, triangle, square, and sawtooth are also available at a single tap. Designed for everyone from beginners to professionals. 4-Track Multi-Timbral Synthesis Each track operates completely independently with its own waveform, frequency, and volume settings. Layer multiple tracks simultaneously to create thick, complex tones impossible with a single oscillator. Professional Controls Frequency Adjustment (20Hz-20kHz) Full coverage of human hearing range. Logarithmic scale slider provides musically natural control from bass to treble. Portamento Function (0-1000ms) Smooth glide effect between pitches. Faithfully reproduces the warm expression of analog synthesizers. Individual Volume Control Fine-tune each track's volume from 0-100%. Achieve ideal balance with precision mixing.
