'What tools (functions/packages/programs) do you use to create long-term spectrograms (LTSA) of .wav recordings? [closed]
I have 72 (1 hour long) continuous acoustic recordings (.wav files) that I would like to merge into a single .wav file. Any suggestions on how to achieve this?
Solution 1:[1]
If you have access to Matlab, the Triton software add-on published by UCSD builds LTSAs, and includes tools to zoom, highlight, and some analysis. It also does not require knowledge of how to program in Matlab to use. :)
Solution 2:[2]
It can be done in sox - http://sox.sourceforge.net/
It's available for most platforms. If your individual wav files were file1, file2, etc, then the command would be:
$ sox file1.wav file2.wav file3.wav ... final.wav
The last file (final.wav) would be the resulting combination of wav files and you can create a normal spectrogram.
You can also use wildcards, since you have so many:
$ sox file* final.wav
Be careful with the wildcards though (i.e. make sure you are only grabbing what you want). Sox is a nice toolkit to have around and it's free/open source.
