App Description
All frequency sound generator tools in one app! Tone generation, sound tests, musical tuning and many more. This app helps if you are looking for generating sounds in different frequencies, analyzing sound and making sound tests which produce sound waves based on the desired tone.
Frequency sound generator includes user-friendly and very high-quality tone generation tools:
• Single frequency generator
• Multiple frequency tone generation.
• Musical notes presets
• Binaural beats
• SFX sound generator
• Sweep generator.
• Bass/Subwoofer sound test
• DTMF tones
• Metronome
• Noise generator
Features:
• Play sound in background: Play your frequency generation sounds in the background while your app is minimized or your screen is off.
• Export all generated sounds to an audio file that you can share.
• Animated wave in the single oscillator tool.
• Frequency generator effects such as Vibrato (FM), Tremolo (AM), Ring Modulation (RM) and also Pulse Width Modulation (PWM) - for square wave only.
• Noise generator effects such as auto-pan and breathing effect.
• Play up to 15 oscillators at once in the multi oscillator tool.
• Play up to 15 sweep oscillators at once.
• Tap your tempo in metronome.
