iAudioApps brings their Voice Analyzer over to iOS as a Universal app. While most music apps for vocalists tend to be either effects or karaoke, this one hopes to improve your singing through informative formant spectograms.
Voice Analyzer iTunes Description:
Voice Analyzer is a real-time spectrum and spectrogram analyzer. It gives you a visual representation of your voice. You can also analyze the sounds of musical instruments, identify spoken words phonetically, or picture the calls of different animals. Generally speaking, the power of the Voice Analyzer is enormous.
The Singer’s Formant is a tonal ‘ring’ produced by a singer. It is visible on the sound spectrum of trained singers (around 2500 to 3500 Hz). This formant is absent in speech or in the spectrum of untrained singers. Its frequency strongly depends on the voice type.
- Fast Fourier Transform (FFT)
- Spectrogram analyzer (color, black and white, fast response)
- Spectrum analyzer
- Zoom and pan
- Measure values
- Move back analysis (just tap on the spectrogram)
- PIP (picture-in-picture), allows the simultaneous analysis on the Spectrogram chart and Spectrum
- Audio input can be supplied via built-in microphone and an external microphone (via the headphone jack, USB audio interface or through the iPhone/iPad dock connector - many Core Audio compliant devices)
- Sharing charts (through mail, social networks, clipboard)
- Frequency scale: linear and logarithmic
- Amplitude scale: linear and logarithmic SPL/RMS (dBFS)
- FFT window sizes: 1024, 2048, 4096, 8192, 16384
Here's an excellent demo, with a male vocalist absolutely nailing the scales.
