tacost allows you to test and characterise the accuracy of your acoustic tracking system. It allows you to create audio recordings to simulate sound emission from known points of your choice, and uncover the maximum expected accuracy of your acoustic tracking system.
If you're reading this on PyPi - then see detailed documentation at: itsfm.rtfd.io
- Creates audio files which simulate sound arrival at each microphone in an array from user-specified points
- Allows customisation of multiple parameters that may affect acoustic tracking accuracy
- Perform the actual acoustic tracking. You need to use a separate system (eg. Sound Finder, TOADSuite, Batalef, or the tracking system of your choice)
- Simulate complex sound propagation (reflection, reverberation,etc). Sound is assumed to travel in straight line paths. In version 0.0.1 there's no spherical spreading too!
The two T's in the logo are tristar arrays (shaped like T's) with four microphones each on them (blue dots). The red dots are positions from where sound was emitted. In this case, I like to imagine it to be a bat's calls as it flew past two arrays!
Creating an audio file to test your system is as simple as opening up your shell/command line and typing:
python -m tacost -run_exampleThe command above will generate a four channel WAV file with 500 kHz sampling rate based on the default array geometry and source positions. See the page on default array geometry and source position.
Update: tacost is currently on PyPi and so you can now pip install tacost!
However if you want the latest version, you can also use tacost with a local install. Head here https://github.com/thejasvibr/tacost and download the repo. From the downloaded
repo open up a shell/prompt and type pip install ./ .
