Play/pause function is independent of gain settings.
Frequency sweep time extended from 0.2 to 60 seconds.
Noise source can be set to correlated (mono) or uncorrelated (stereo).
Frequency range boundaries conform to ISO frequencies.截图应用描述Signal Generator is an app that produces audio test tones. The basic app produces sine waves, and it can be extended and customized (via in-app purchases) to produce white noise, pink noise, frequency sweeps, and (on iPhone 4 and better) square waves, sawtooth waves, and triangle waves.
• Free Tone Generator. The app includes a free sine wave generator that generates signals from 20 Hz to 20 kHz, with a 48 kHz sample rate, 16-bit samples, and 96 dB of dynamic range. Frequency control via logarithmic knob or keyboard input.
• Pro Tone Generator. (Optional in-app purchase). Extends the frequency range down to 1 Hz, and adds stereo control and buttons to increment the frequency in steps. Anti-aliased square waves, sawtooth waves, and triangle waves are generated with aliasing kept to -54 dB or less.
• Noise Generator. (Optional in-app purchase). Produces white noise, pink noise, and brown noise. Pink noise falls off at 3 dB per octave (±1 dB). Brown noise falls off at 6 dB per octave. Option for stereo uncorrelated noise, or mono correlated noise.
• Frequency Sweeps. (Optional in-app purchase). Adjustable start and stop frequencies. Linear or logarithmic sine wave frequency sweeps. Single shot sweeps, repeating upward sweeps, and upward/downward sweeps.
This app can be used to:
• Test Speakers and Headphones
• Balance your Home Theater System
• Tune Your Car Audio System
• Mask Environmental Noise
• Burn In Headphones
• Tune Musical Instruments - 版本: 1.7.32015-07-08更新日志
Fixed a crash that would occur during start up under certain conditions. Fixed the sweep mode button forgetting its last state.
