Avisoft  動物聲音分析軟體

Avisoft-SASLab Pro is a powerful Windows application (compatible to Windows XP/Vista/7/8) for investigating animal acoustic communication. It provides a broad range of processing and analysis tools that can greatly increase the efficiency in extensive sound analysis projects.

Avisoft-SASLab Pro is compatible:
Supports all common soundcards and USB audio interfaces
Opens .wav and .bwf files that have been recorded by any solid state / hard
     disk field recorder
Imports soundfiles that have been recorded with third-party sound
     recording/processing tools (.WAV .BWF .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
Exports georeferenced field survey data by means of .txt, .kml or .gpx files into
    GIS applications (including Google Maps / Google Earth)
The software can be configured for touch screen operation in order to facilitate
     its use on tablet PC's.
　

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
Heterodyned payback of (full-spectrum) ultrasound recordings
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 (also referred to as geocoding, geolocating or geotagging) .wav
     files that have been recorded with a digital field recorder by using GPS track
     log data (see the Bird Species Map and SONY PCM-M10 samples)
Creating field survey maps from labeled or renamed (with filenames containing
     species prefixes) .wav files that can be easily imorted into GIS applications,
     including Google Maps or Google Earth (see the Avisoft Bat Survey sample).
Synchronizing audio and video recordings by using SMPTE or LANC time
     code information (both reading and writing)
Advanced metadata management capabilities including user-defined database
    fields that can be collected into a virtual (XML-formatted) metadatabase, which
    can subsequently be queried within the Avisoft-SASLab Pro software.
Batch and real-time processing for managing large numbers of sound files.
　

System Requirements
Avisoft-SASLab Pro is compatible with any PC running Windows XP, Vista, 7 or 8 including Intel-based Apple Macintosh running Boot Camp, Parallels or similar virtualization software.

Automatically measuring sound parameters on the spectrogram:

A dedicated Puls Train Analysis option supports the temporal analysis of amplitude envelope patterns. Both complex pulse group analysis and simple counting of vocalizations is supported:
