I am currently working on anthropogenic effects on the vocalisation of howler monkeys in the urban environment.
I record the vocalisations with a TASCAM DR-07MKii and I want to extract acoustic measurement such as frequency, pitch, rates and lengths of vocalisations.
Which program is easiest to use for a beginner to extract these variables?
I currently have: Sound Analysis Pro, Praat and Audacity.
All tips and additional information are very welcome
If you want to perform an acoustic analysis, Audacity is not a good idea. It is designed for music edition and you don't need that.
Praat is a good option: you'll find a lot of tutorials and video-tutorials on the internet and you can easily get pitch or intensity, but is optimized for human voice. You may have to change some of the visualization options in order to better see your sounds (or find the pitch).
I work with human voice and I have never used Sound Analysis Pro .
Hello,
I would recommend praat as this tool offers all you need and has additional features which may help in doing your analysis. Praat offers also the opportunity to extract the file-data into excel - it is a little bit tricky but it works and therefore allows further analysis of the date
I agree that Audacity is of no use-- it's primarily an editing program, not for measurement. Praat and SAP would both probably work for the simple measurements you described. I believe Praat (which was developed for work on speech) has some tools for measuring speech-related features such as formants, which might be useful for nonhuman primate vocalizations. Raven Pro (http://ravensoundsoftware.com/) has (I'm told) an easier learning curve than Praat and includes basic time, frequency, and relative power measurements (though no formant measurements). Measurements and annotations are easily exportable to Excel or stats programs via tab-delimited text files There's also a set of freely available tutorial videos available (see "Training" on the Raven website).
I recommend RavenPro for analysis and measurements of animal vocalizations. Currently myself learning how to work with Raven, but it seems very reasonable and practical software.
I agree that Audacity is a little developed software to make measurements and structurally characterize the vocalizations. I would recommend the use of RavenPro (http://ravensoundsoftware.com/); Adobe Audition (something more complex and less intuitive than Raven); and if you are familiar with the R platform, Seewave can be a very good option (see https://marce10.github.io/)
Best regard, Pablo
Hi.
I am using at the moment a very similar TASCAM model to obtain bird sound registrations in the Canary Islands, and I agree with some views expressed here about that Audacity is not the ideal program to do a full and more in-deep anaylisis of the sounds. It is good to cut parts of an extended registration and to do other things, but it has limited functions.
Best regards, and good luck in your work.
