Sound Analysis and Synthesis Software
Avisoft-SASLab Pro
Avisoft-SASLab Pro is a powerful Windows application (compatible to Windows 98/2000/XP/Vista) for investigating animal sound communication. It provides a broad range of processing and analysis tools that can dramatically increase the efficiency in extensive sound analysis projects.
Avisoft-SASLab Pro is compatible:
- Supports all common sound cards, compact flash and harddisk audio recorders
- Imports soundfiles that have been recorded with third-party sound recording/processing tools (.AIF, .SND, .AU, various binary formats and .txt)
- Exports images and measurement results as files (.wmf .bmp, .tif, .txt), via clipboard or through DDE directly into Excel
|
Avisoft-SASLab Pro is
comprehensive:
- Color-coded spectrograms (FFT size of 64 to 1024 points), high quality
spectrogram output with TrueType fonts
- Real-time spectrogram display with circular buffer recording
- Digital filtering for removing noise
- Flexible cursors for measuring spectrogram structures
- Versatile automated sound parameter measurement and
classification facilities (event detection, analysis, classification and statistics)
- Labeling option for single point and time section labels
- Magnitude- and Powerspectrum, Linear Predictive Coding (LPC), Auto- and Crosscorrelation,
Cepstrum, Histogram, 2D and 3D Scatterplot, 3D Waterfall display,
Impuls-Density-Histogram, Envelope and Instantaneous frequency using
hilbert transformation, frequency shift using FFT technique, Root
mean square, Sound similarity matrix for comparison of
spectrograms
- Synthesizer for generating artificial songs and calls by mouse
drawing of the parameter evolution (fundamental frequency, envelope,
harmonics, frequency and amplitude modulation). Listen to a few synthesized bird songs.
- Automatic harddisk recording for long term monitoring based on a
frequency selective trigger
- Automatic Response option for automated playback experiments
based on real-time classification and re-synthesis
- Automated classification of syllables by means of spectrogram
cross-correlation with templates
- A dedicated pulse train analysis tool supports the investigation of temporal patterns of both simple pulse trains or series of sound bursts (e.g. song elements)
- and much more ...

What the experts say
"The
combination of these features means that the software pretty much
lives up to the claims made in the advertising flyer that it is easy
and intuitive to use." ... "Avisoft provides cheap, powerful sound
analysis for PC's." ... "If you already have an IBM-compatible
computer of the appropriate specification, then Avisoft is a most
attractive package."
Peter K. McGregor, Nottingham University
and Jo Holland, University of Copenhagen: Review in Animal
Behaviour, 1995, Vol 50, No 10
"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
"I’ve 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."

Monitoring Programme, Bat Monitoring Post, edition December
