Avisoft-SASLab Pro 聲音分析綜合軟體

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, .htm, .xml, .sql), 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
     
  • Octave and Third-Octave Analysis for noise level measurements
     
  • 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
  • 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)
     
  • Georeferencing .wav files that have been recorded with a digital field recorder by using GPS track log data
     
  • and much more ...


 

System Requirements



Avisoft-SASLab Pro is compatible with any PC running Windows 98, ME, 2000, XP, Vista or 7 including Intel-based Apple Macintosh running Parallels or Boot Camp.

 

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."
Jon Russ: Review in the newsletter of the UK National Bat Monitoring Programme, Bat Monitoring Post, edition December 2002.
