See your voice, music or test your audio equipment. See whatever your microphone can hear!
This real-time spectrum analyzer (RTA) / audio visualizer features:
- 256 high-quality frequency bands [20Hz to 24kHz]
- Logarithmic frequency scale to match human perception
- Low latency for high responsiveness
- High frame rate to see smooth frequency and amplitude movements
- Low battery drain due to high performance code
- Fast graphics using OpenGL ES 2.0
- FFT window size 4096 @ 60 frames per second
- changed sampling rate to 48 kHz, improving the support for iPhone 6s and iPhone 7, and improving the quality in general
- uses the measurement mode, minimizing the amount of system-supplied signal processing
- should now have a flat frequency response curve (influenced by microphone characteristics)
Ratings and Reviews
Everything I need. Thank you for including the frequencies at the bottom of the graph! Better than others and less expensive? Sign me up!
Doesn't work IOS7.1 - black screen
Just bought. Does not seem to work. Just a black screen. Sent inquiry, got answer quick (IOS setting) and works great. Using to get used to special hearing aid.
A lot smoother then other frequency analyzers. The simplicity of it also helps. I think there should be a "How to use this" page, explaining what the user is seeing though.
