Audio Tone Generator Lite 6.1

"Audio Tone Generator Lite" is a sophisticated audio signal generation application designed for iPhone, suitable for professional and hobbyist audio testing. It provides precise tools for evaluating audio equipment, loudspeakers, listening environments, room acoustics, and hearing function.

The app offers the ability to generate key audio reference signals including Sinewave, Sinewave Sweep, White Noise, and Pink Noise. These signals are most effective when used alongside external measurement devices such as spectrum analyzers or sound level meters.

Key features include:

• Sinewave signal generation with preset frequencies: 500Hz, 1kHz, 4kHz, 16kHz
• Frequency sweep capability with presets: 200Hz - 4000Hz and 20Hz - 20000Hz
• Manual frequency input via keyboard with 1Hz precision
• White Noise and Pink Noise generation
• Frequency range support from 20Hz to 20,000Hz
• Output gain control
• CD-quality audio output

Potential applications encompass:

• Loudspeaker and headphone testing
• Tuning audio amplifiers, equalizers, and other audio equipment
• Acoustic environment analysis
• Frequency response measurement using noise signals
• Sound masking solutions
• Mediation and relaxation utilizing broadband noise (Pink Noise)
• Hearing threshold assessments to determine the maximum audible frequency
• Generating mosquito sounds aimed at teenagers

Important notes:

• After entering a numeric frequency value on the keyboard, press the Return key to confirm your input. In Sinewave Sweep mode, enter two numeric values consecutively and press Return after each.
• Caution should be exercised when producing high-frequency signals at high volumes to prevent potential damage to loudspeakers, even if the sound remains inaudible to the human ear.
• Using this app with wireless connections such as Bluetooth or AirPlay may result in limitations such as reduced frequency response fidelity, lowered output levels, or irregular noise due to environmental interference. Such issues are outside the scope of the app's guaranteed performance.
