Description

Audio Analyzer is a real-time spectrum, spectrogram, oscilloscope and octave RTA analyzer. It gives you a visual representation of an acoustic signal. It can be used to analyze the sounds of musical instruments, to identify spoken words phonetically, to measure the frequency response of audio equipment, or to picture the calls of different animals. You can also check “The Singer’s Formant”, the most important measure for every opera singer.

Features

- Spectrogram analyzer (color, black and white)
- Spectrum analyzer
- Oscilloscope (full FFT window size)
- Octave RTA analyzer: bands - full, 1/3, 1/6, 1/12 (RMS values)
- SPL Meter (dBFS)
- Recording trigger (triggered by frequencies in the specified frequency band)
- Fast real-time response
- Sampling rates: 44.1kHz, 48kHz, 96kHz*
- Fast Fourier Transform (FFT)
- Window sizes: 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536
- Variable frequency resolution of the spectrogram
- Variable between FFT computations time interval (time resolution)
- Max/min Octave RTA values
- Zoom and pan all charts
- Measure values in all charts
- Play back analysis (just tap on the spectrogram and play)
- PIP (picture-in-picture), allows the simultaneous analysis on the spectrogram chart and Second chart: Octave RTA, Spectrum or Oscilloscope
- Audio input can be supplied via the built-in microphone, and an external microphone* (via the earphone jack, via the USB camera adapter, or through the iPhone/iPad dock connector – Core Audio compliant devices). External devices are shown in the application only when connected (e.g. external mic connected via the earphone jack)
- Sharing charts and audio recordings (through mail, social networks, clipboard)
- Exporting to the iOS Document Browser (supports iCloud): audio recordings (wav) and image charts (png)
- Importing audio files from another application or from the iOS Document Browser (supports iCloud)
- Many formats supported for audio file import
- Automatic conversion from other sampling rates for imported files
- Frequency scale: linear and logarithmic
- Amplitude scale: linear and logarithmic SPL/RMS (dBFS)
- SPL meter weighting: dBZ - linear


Make sure you use the latest iOS update.

*For 96kHz analysis use an external microphone with such capabilities through a USB camera adapter or through the iPhone/iPad dock connector (internal mic or external mic connected via the earphone jack can only be used for 44.1kHz or 48kHz analysis) You can also import files recorded on an external device.

My "Go To" App for Live Sound

MioMC

When I want to know what I am missing in a mix or to find a problem frequency, Audio Analyzer tells me and takes the guess work out of making needed adjustments to the mix at our church. ID ringing frequencies with the RTA or spectrograph or double-check your EQ at a glance. Intuitive to use and definitely worth the $4.99! Thank you for making such a great app!!!

So far, awesome

Exactly what I need to ring out FOH and monitor wedges. Waiting for micW i436 to arrive. 5 stars will stick if the app performs with the external mmm microphone.

my favorite spectrum analyzer

OregonCoast2

I practice playing a Bb trumpet using this spectrum analyzer, chromatic tuner, metronome, and audio recorder. Studying my sound in the frequency and time domains helps improve my playing.

I would suggest the following feature to be added: Allow the user to preset the range of frequency and time. The current version allows the user to zoom in or out using 2-finger gestures. Because the region of interest for me is between 0 and 3 kHz, and because I need to view that region in detail, I need to adjust the frequency scale every time I use or reset the app. Furthermore, the 2-finger gesture sometimes bounces the scale such that the origin is not 0 kHz 0 seconds. Allowing the user to select the default range of frequency and time would save lots of time.

Thanks for a nice product.
