AudioAnalyser is a realtime frequency analyser for audio signals.

You can combine the "AudioAnalyser" with my other application "Multisine", if your soundcard supports the full duplex mode (only very old soundcards don't). With this combination you have a full equipped audio suite for your measurements.

1. Samplingrate 8000 Hz ... 96 kHz
2. FFT length 1024 ... 32768 points
3. Stereo and Mono mode
4. Averaging mode (1-20)
5. Max hold mode
6. 5 different windows (Hanning, Hamming, Blackman, Blackman Harris, Rectangular)
7. Linear and logarithmic frequency axis
8. Vector Scope for stereo width and phase analysis
9. Real PPM Meter
10. 2 markers (Deltamarker) available
11. Variable axis settings
12. Level Correction value
