Hi,


We are pleased to announce availability of AQuA version 7!


AQuA is capable to work with audio files represented in WAV format. Audio files should have the following parameters depending on the version one uses:

















AQuASample rateBits per sampleCompressionsChannels
Voice8kHz8, 16, 24, 32Uncompressed, a-law, u-lawMono
WB8kHz – 192kHz8, 16, 24, 32Uncompressed, a-law, u-lawNot limited (16 channels max)

Main advantages of AQuA perceptual model are:


  • Language independent

  • Capable of predicting MOS score for short sequence of speech (less than 4 seconds)

  • Capable of predicting MOS score for long sequence of speech (longer than 30 seconds)

  • Capable of evaluating different types of audio: various bit depth, sampling frequency, Mono, Stereo

This version has extended report on reasons for voice quality degradation providing additional metrics, which you can find in bold in sample report below:


Duration distortion.


Audio stretching corresponds to 1.41 percent.


Delay of audio signal activity.


Signal delayed by    100 ms.


Corrupted signal spectrum.


Overall spectral energy distortion approaches 61.58 %


Vibration along the whole spectrum [-14.31, 47.27] %


Significant distortion in low frequencies band.


Energy distortion approaches 31.47 %


Spectrum vibration in low frequency band [-12.52, 18.95] %


Significant distortion in medium frequencies band.


Energy distortion approaches 27.22 %


Amplification approaches 25.42 %
