What the experts say

"I find Avisoft is a joy to use. The facility and speed with which the user can assess long recordings using the real-time display, prepare and print sonograms and other spectra quickly or export them to other Windows applications, while in full control of the analysis and display parameters, makes this an invaluable programme for bioacoustic research and education."
Richard Ranft, National Sound Archive London: Review in Bioacoustics 1995, Vol. 6, No 3

"Iíve been looking for a number of years for a software package that allows the user to simply rub out superfluous portions of the sonogram and with SASLab Pro I have finally found one."

Examples of Avisoft-SASLab Pro measurement and classification facilities

Power spectrum with automatically generated labels showing peak frequency and relative amplitude

Spectrogram with Automatic Parameter Measurements showing start frequency, end frequency and maximum peak frequency for each element.

Numeric display of the Automatic Parameter Measurements of the spectrogram shown above.

Histogram of the distribution of start frequencies (resolution=200Hz, n=13)

Parameter measurements imported into an Excel spreadsheet (by pasting from clipboard or by automatic DDE transfer).

Element classification based on start frequency and element duration.

Element type sequence and element type statistics pasted from clipboard.

3D-Scatterplot showing automatically classified elements together with the boundaries used for classification. Classification is based on peak frequency at start, frequency change from start to end (parameter named 'derived1') and element duration.

Examples of Avisoft-SASLab Pro Graphic Output

Automatic Response Option

Synthesizer

The integrated Graphic Synthesizer is able to generate artificial sounds and to modify natural sounds:


Spectrogram of a natural nightingale song

Spectrogram of the re-synthesized song with some modifications (a harmonic has been added to the second element and a frequency modulation has been applied to the third element).

Fundamental frequency and amplitude envelope taken from the natural song spectrogram were used to re-synthesize the song.

Spectrogram of a natural penguin song.

Spectrogram of the re-synthesized penguin song with the amplitude of the second harmonic decreased and the third harmonic increased.

Multichannel Analysis

SASLab Pro can process multi-channel files containing up to 8 channels. These files may have been recorded by Avisoft-RECORDER or by other third-party recording equipment (RAW multichannel files can be imported into SASLab Pro)


4-channel file display

Multichannel cross-correlation analysis showing the points of maximum correlation between all 4 channels (for time of arrivial measurements)
