AudioAnalyser is a lightweight software application designed as a real-time frequency analyzer for audio signals. It can be used with multisine, an audio signal generator, in case your soundcard supports the full duplex mode.
The GUI looks easy and easy to work with. The utility shows a spectrum analyzer directly in the main window which processes the information in real time.
In addition, you can easily start or stop the analyzing process and work with the built-in PPM (peak program meter) instrument in order to check out the level of an audio signal.
There’s no support for a help manual so experimenting with the built-in features is your only chance in order to understand how the tool works.
AudioAnalyser configuration settings
AudioAnalyser offers you the possibility to adjust the sampling rate, FFT size, frequency axis (linear or logarithmic), number of channels, as well as set up two markers. What’s more, the utility comes with support for stereo and mono mode, maximum hold mode, five different windows (Hanning, Blackman, Blackman Harris, Rectangular), as well as vector scope for stereo width and phase analysis.
Tests have shown that the application carries out a task quickly. It doesn’t eat up a lot of CPU and memory, so the performance of your computer is not hampered.
- The sampling rate of 8000 Hz to 96 kHz.
- FFT length 1024 to 32768 points.
- Stereo and Mono mode.
- Averaging mode (1-20).
- Max hold mode.
- 5 different windows (Hanning, Hamming, Blackman, Blackman Harris, Rectangular).
- Linear and logarithmic frequency axis.
- Vector Scope for stereo width and phase analysis.
- Real PPM Meter.
- 2 markers (Deltamarker) available.

- Level Correction value.
All things considered, AudioAnalyser provides a user-friendly layout and several handy audio settings for helping you work with a real-time frequency analyzer. The intuitive feature pack makes it suitable for rookies and professionals alike. On the downside, it hasn’t been updated for a while so you can make use of its capabilities especially if you are the owner of an old operating system, such as Windows 2K, XP, Vista, and 7.
