About

Waveform Sound Generator

Generate custom sound waves with a single oscillator. Control wave shape, peak characteristics, and frequency to explore the physics of sound and human perception. Ideal for education in physics, music, and sound.

Highlights
  • Customizable waveform generation
  • Single oscillator
  • Control peak number, direction, amplitude, and sharpness
  • Explore sound physics and perception
  • Frequency range 0.2Hz - 20KHz
  • Arbitrary waveform with up to 10 peak control points

Read full description

This is a sound or signal generator with one oscillator. It can play customisable wave form so you control the number, direction, amplitude and sharpness of the peaks. This instrument clearly demonstrates the physics of the sound and most importantly you can see that humans do not hear frequencies but amplitude acceleration (or peak sharpness). Also the peak position or direction inside the sound wave has no impact of human perception for the sound. You can even hear 0.2Hz sound of the peak is sharp enough and the frequency (self repetitiveness) of the signal is not actually meaningful for our ears. In nature there are no perfectly repeated waves and the sound has more free wave nature so what is important fo our sound recognition abilities is the peaks sharpness and the number and amplitude of those peaks :) Frequency domain and FFT for music can’t be more wrong and misleading. So work in time domain and handle those peaks to move the science and music ahead! The app can be used for physics, music or sound, education or what ever. Oscillator range 0.2Hz - 20KHz Arbitrary waveform with up to 10 peak control points. Peak width and possible peak vibration Stop using FFT for sound - it is CPU expensive and dead wrong :)

About

Pitch Scope

Analyze sound in real time by visualizing its pitch, waveform, and spectrum. Explore the acoustic differences in voices and musical instruments. Understand how different sounds are represented visually.

Highlights
  • Real-time pitch measurement
  • Waveform display
  • Spectrum analysis
  • Voice and instrument sound analysis
  • Visual comparison of sounds
Features
Read full description

The pitch scope app measures sound from the microphone and displays its pitch(frequency), waveform, and spectrum in real time. Use this app to analyze voices and instrument sounds. Why do vowels U O A E I sound like U O A E I? You can see and check the waveform and spectrum of each vowel.  When you hear someone says “this guitar sounds brightly and that one sounds heavy”, what is the difference? For such a question, you can check it with this app.

Verdict

The call

The clearest difference is review sentiment: Waveform Sound Generator at 75% against Pitch Scope's 0%. Waveform Sound Generator also leads on price ($1.99 vs $2.99) and iOS requirement (10.0 vs 17.6). Pitch Scope's advantage is update cadence (every 3 months vs every 8 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
